Question and Advice
      #6203483 - 11/19/13 10:55 AM

Good Morning,

I hope that I don't get killed for this post. The last Time I asked a question about Questars on the Classic Forum, I created a firestorm. What is it about these scopes that cause quite a stir?

I have heard so many good things about Questars and am excited that I might be able to buy one. I have been in astronomy for about one year and own an Orion 8XT Dobsonian. I have a good assortement of eyepieces. I enjoy using it but sometimes I just don't feel like lugging it out of my garage. I am looking at buying an older Questar (3.5) and was thinking about using it as a grab n go telescope. Would this scope make a good "garb n go? I have only seen pictures of them so I don't know what to expect.

I heard that the optics are good. What about eyepieces? Can you use any type or do you need to buy special ones? Any help, advice or opinions would be greatly appreciated.

Thanks,
Jack

Excellent grab n go on its supplied legs for tabletop use, or with a tripod. Resolution and light grasp won't compare with your eight-inch Dob, but a Questar is very compact, very light (about seven pounds), and of superb optical and mechanical quality. Built-in Barlow, and the finder is accessible through the main eyepiece with the flip of a lever. Wonderfully smooth slow motion controls, no collimation necessary, and unparalleled support from a company that's been making scopes in the USA since the mid-1950s.

Plus, it tracks (at both sidereal and lunar rates if equipped with Powerglide II), so you won't have to constantly nudge it along to keep object in the eyepiece.

I'm with Hank. Questar has to be something like the original "grab-n'-go," designed and launched when the typical telescope was the 3" or 4" refractor on a less-than-wieldy equatorial mount. I have two other scopes, one larger and one smaller than the Q, but the Questar is the one I use the most precisely because it is so easy to set up and use.

As far as eyepieces: the newer Questars accept both threaded Brandons and standard 1-1/4" eyepieces. To use 1-1/4" eyepieces in an older model, you will need an adapter such as the one TeleVue sells. I don't know what year Questar made the change, but someone will know. My Questar is an '06 model and accepts both types of eyepieces.

"My home observing is primarily Questar-based, utilizing an aluminum pier that can be removed for mowing and replaced without losing polar alignment." These words are from RRavenberg. They were from the Ravenberg Scope Gallery before he passed on. He made telescops from 17" dobs to much smaller refractors on very unique mounts. But at home he used a 3.5" Quester. There is now a Ravenberg Memorial Scope Gallery but the Questar section with the all the photo's of how he used his Questar is missing. I would like to see that part restored. I feel that showing how Ravenberg had access to all kinds of telescopes, but that the Questar had a unique place at his home, would show the complete Ravenberg and help others make a decision on owning a Questar. I'm really glad I saved that thread and many others from CN on my computer. Hope this helps Copernicus1473

It literally takes minutes to set up and break down. Not to mention if you're using the supplied legs on a table top (I use a hefty picnic table) you can do it all comfortably sitting down. Atlases, iPad, etc. all within easy reach on the table! The viewing experience is so seamless and effortless.

Wonderfully crisp views. Only 3.5 in, yes, but I can count on one hand the number of times seeing provided me with optimal 8 in views with my C8.

Of course the C8 beats it on clusters and galaxies but once again my city skies are so light polluted that lunar, planetary, and double star viewing is what I do anyway. Q rocks here.

I must say I have never yet taken the little Q to a really, really dark site. I'm curious how it performs there.

Jack,
The Q's have tremendous versatility. One day last summer - with my duplex - (1) imaged damselflies landing on cattails in the pond at 25' distance and able to resolve the critter's compound eye structure (2) later inspected the coaxial cable attachment to my ham radio antenna @ 50' on a tower while sitting on the deck (3) Put it on the tristand to check out the "night's best".

Brent,

The 1994 model was the last year that the Diopter Adapter would only work with the Brandon EPs. In 1995 they started to produce the Diopter Adapter that will accept all EPs (a copy of the TV adapter). Questar can supply their adapter to pre-1995 Qs (I think they are about $85) and you just screw out the old one and replace it with the new one.

Thank you for your posts and encouraging words. Looking forward to getting the scope and will post some pictures once I get it. That is if I can figure out how to do it? The weight, portability and ease to setup and take down is what I am looking for (sounds like an ideal grab n go scope). I live in a dark sky area which will only enhance the viewing.

I heard good things about the company and their customer service, and the fact the they are located in the United States and has been in business for awhile is a big plus. Glad to hear that you can buy an adapter so that you can use other EPs. I have been looking on the internet and the Brandon EPs are expensive.

Thanks again for your input. It is greatly appreciated!

Jack

Call Questar for the manual. They'll also be able to tell you the age of the scope from the serial number that's on the bottom of the base. Enjoy the scope.

Questar's diopter adapter will accept all 1.25" eyepieces starting in around 1972, but in 1995 they added a couple of nylon setscrews to hold the eyepiece in place. Before '95, you could just drop the eyepieces in. If you need to replace the diopter adapter, TeleVue also sells one, but get the one from Questar, it's really much nicer.

Hello Jack,

I recently purchased an older 3 1/2" Standard which came with the earlier eyepieces that have a built in focuser. They uses a smaller 1 3/16" adapter tube as seen in the left of the photo.

A Tele Vue 1 1/4" adapter was also included, but like the adapter for the early version of the Questar eyepieces, has no provision for focusing an eyepiece for finder use (photo center).

I contacted Jim Reichert at Questar for a current focuser diopter adapter. It fit perfectly, (right of photo) and enables the use of threaded Questar Brandons, non threaded Brandons, and other 1 1/4" eyepieces. The price was $85 plus shipping, well worth it in my opinion.

Note that not all eyepieces will come to focus with the Questar "finder". There is a list of those that do, but I don't recall where at the moment; perhaps someone will chime in with a link. Hope this is helpfull.

Thank you you for all of your help. I will be picking it up today and will call Questar Monday morning. I was going to try it out today or tonight but will wait a few days. Hopefully it will get a little warmer. Right now 10 degreesa and wind gusts to 35 miles per hour.

I will probably have a few more questions once I get it and start to use it. You are all a great group of people and from reading the posts very knowledgeable. Thanks for sharing!

Have a great day.

Jack,

You have a very very early one. It was 55th Questar to come off the production line (I understand the first production Q has the serial number 50). The R stands for modified or reworked, remanufactured, replaced or revised at a later date (Questar could probably tell you what was done). The 8 is the last digit of the year it probably was reworked.

You are a lucky man, Bill

Bill,

I did not know that you could tell so much about the scope based on its serial number. I do feel very lucky and fortunate about getting it. I have heard so many great things about Questar telescopes. Though I am not sure that I totally understand about how lucky I am. Is there much difference between the older and newer scopes? I figured that the older scopes would not be as good in optical quality due to all of the advancements in astronomical equipment over the years.

Jack,

There have been small modifications over the years but all of the Qs have the same general outside look. I think that the first 100 to 200 were the same but minor internal changes were made after that (different mirror maker, prisim and base plate). That makes yours a collectors type scope (much fewer in number than later designs). The mirror in your scope was made by one of the best in the business and I think another mirror maker came after the first 100 to 200 so the optics in yours are probably better than later ones. I think yours is probably worth $500 to $1000 more than a Q made after the first 100 (to a true Q collector).

That does not mean you should not use your Q. That is what they are for and you need to really enjoy it. These ladies enjoy being taken on a date.

Bill

Bill,

I never would have thought that about the mirror and optics being better. I do plan on using it and can't wait. It seems like a good compliment to my 8-inch Dob. It probably could use a cleaning so I will contact Questar ansd send it to them in January. Usually I don't get a chance to do much viewing in January (I live in New Hampshire) due to the cold. Though those clear cold nights are very tempting as long as I dress appropriately. There are also no bugs

Best Regards,
Jack

Congratulations on finding that early Q!

The early scopes have been discussed extensively over the years. It is generally thought that the optics for very roughly the first 900-1000 were made by Cave. Since then the optics have been made by Cumberland Optics. It is further generally thought that modern optics are better than earlier Q's, and that is true of modern Q's verses, say, 1960s Q's.

You should be aware that if you send it in for a full cleaning that Questar will replace any parts, including cosmetic parts, that they deem necessary. For example, the Logo disks, especially the one at the center of the RA drum, may be replaced as a general rule since removing them may damage them. Those logo disks have changed over the years, and old disks are very distinctive.

Did you get the old English Leather case? That case is very distinctive, the hinge of the front door being integral to the leather. Original units with good working hinges are rare, just due to the ravages of time and the tendency of leather to crack.

People that buy very old Q's, like yours, often will not have them "routinely serviced" because it starts you down a path of modernization that conflicts with the idea of keeping it truly "unmolested" and true to the era PURELY for collectable reasons. From a functional point of view, the factory will restore the unit to modern performance standards, and that is their objective if you don't specifically talk to them about preserving things.

You may not care at all about collectability, but others may, and that scope has collectable value. It has always seemed to me that it does not make a lot of sense to buy a very early Q purely for functional use, for the reasons I am struggling to explain here

If you were to effectively "swap" it, in some way, with a more modern scope it may cost less in the long run (depending on what happens on the next service of either scope) and you don't have to struggle through the collectable issue.

I am NOT suggesting you sell it and do what I just suggested. I am trying to give you a feel for the choices that seem to be inevitably made when a service is done, and what might make the most sense purely from a functional point of view.

And, no, I don't have the spare bagels to buy your Q, although if I did I would. And never service it unless absolutely necessary, and after careful consultation with the factory as to exactly what they plan to do with it.

The early Q's, the collectable aspects, and "renovation issues" have been discussed extensively over the years in the yahoo group list. You might start there with a search for "Cave" or other search terms. ANd, of course, start here, but I know some interesting stuff has been posted over the years on the Yahoo group.

I also meant to add to the above that all those collectable issues may be a moot point since the serial number seems to imply it has already been renovated. So your first course of action would be to contact Questar and see what they did.

It is my understanding that if the serial number was changed, then the base plate was replaced, and it would have been replaced with a metal bottom plate. The earliest Q's had a synthane base, and yours probably did too.

The Yahoo group archives includes a spreadsheet file listing a number of differences between units of various eras, according to data and serial numbers provided by members. It is a very good resource in order to start to understand the changes made over the years. For example, which units had that synthane base (and synthane tube too).

Neil,

Thank you for the information and PM. I will need to do some additonal checking on this Q. I had been looking for a Q for about 6 months to use as a "grab n go." I really liked the portability aspect and the great ruputation and optics.

I saw an ad and contacted the seller immediately. I was probably very lucky because I was local and they did not want to ship it. Being a novice to Q, I didn't think or know to ask about the serial number. The original owner of the scope was Cyrus Fernald of Wilton, Maine. I think that I will need to do some more research on this Q. This is really fascinating and I think finding out more about this Q is going to be great learning experience. I will also check out the other location that you mentioned.

Best Regards,
Jack

Alright, so now I own an early Q. I still haven't had a chance to use it due to the weather...figures. I now feel torn about getting it cleaned and serviced versus keeping it in its current condition. When I was trying to purchase the scope I wasn't even thinking about it as being a collectable; my sole purpose was to use it.

Any words of advice?

What if you upgrade the components that YOU think increase the useability for the way YOU want to use it, but keep the old parts? Not that all parts are user-replaceable, but I think this would keep more options open for yourself and for future owners.

Use it. Get educated. First do no harm. No rush unless you have compelling issues. You can always send it in "next week" but you can never undo a service/renovation/update.

The most common reason to send the scope in is slipping dec or RA clutches. If you scope responds to the controls without slipping then you are good to go. Next would be dirty optics. Unless they are grossly dirty it isn't a problem and they really should not be cleaned more than absolutely necessary.

You should call the Mother Ship and see what was done to warrant that "8" in the serial#. If it was already modernized then your decision was already made by a prior owner. Find out the date it was serviced. If it was in the last 10 years, then there may not be much reason to send it in just for the sake of sprucing it up.

And also post images here! The scope, accessories and case. Close ups are helpful. Everyone likes to see pix of older scopes.

It is interesting that you fell into this by accident. A mixed blessing, eh? Probably rare.

@minirocks... two problems, one is that you might not get them back, for whatever reason.

The second, and more likely, that some very important parts, from a collectability point of view, are more or less destroyed (or damaged) in the process. I am thinking about those logo'd disks on the DEC arms. They are glued on and they may bend or crease on removal. I am not positive about that but it would be the first question I asked.

Most of the controls are obvious when you use them, but you might not be familiar with setting circles.
Questars have nice big (and therefore accurate and useable) setting circles. If you haven't used used these before then you should learn. With practice they can be astonishingly accurate.
Are they Retro? You bet, but utterly useful. Learning to use them is like finding a treasure of ancient wisdom.
It's like finding out what the aperture ring on a camera does to the depth-of-field in the photo.
It's like finding out that an old slide rule with a BI scale is a parallel processor that can, with a single setting, simultaneously calculate the magnification of every possible eyepiece with your scope.
You, too, can become part of the elite priesthood, my young grasshopper.

I will not send the scope out until I get a chance to try it out first. There seems to be a lot to learn about the Q. I contacted the "Mother Ship" to see what was reworked/revised and they said that the records for that scope was archived off-site.

In talking with the seller, she said that the scope belonged to her great uncle Cyrus. Unfortunately he died in 1979 and the scope was in storage until now. So any modifications had to have taken place prior to 1979. I will take some pictures and try and post them tomorrow morning. Hopefully, I can make them small enough. The case appears to be leather and looked to be hand-stitched. The case is not in very good condition. There are also other pieces that I have no idea what to do with them or what they are. Any information onthem would be a big help. I can take other pictures if these aren't detailed enough.

Thanks to all of you for your help!

You could buy a modern manual from the factory. That manual has good instructions for doing polar alignments and using the circles.

Basically you need to get the polar axis aimed at the North Celestial Pole. Then acquire a known bright star reasonably close to the celestial equator (at least well away from the pole) in the eyepiece and set the RA dial to match the known RA of the star. Now you can find an object by dialing in RA and Dec.

The simplest (but less accurate) way to get the polar axis aligned is to set Dec to 90 degrees and then, without changing Dec, get the North Star centered in the eyepiece.

The North Star is actually 3/4 degree away from the true pole. The manual has a nifty way to adjust for that.

Here is an old thread about "painless polar alignment".

It is usually best to get very familiar with the Q during daytime before you try things like polar alignment at night. Try birding

Did you get a dew shield with the star map? If you did, a nice clear photo would be nice.

Photo of the rear control box, and the underside diagonal mirror. Photo of the bottom of the mount. Photo of any other accessories, such as additional eyepieces (should be two EPs).

A couple notes on differences with modern versions...

1. The eyepiece appears to be one of two "Japanese" eyepieces supplied, a Konig and an Erfle. That was later changed to the current Brandon EPs, with threaded barrels. I think it is possible to mod (replace) the EP adapter to work with the new screw in types, as well as standard EP's.

2. The diagonal that diverts the image to the top EP port is an Amici prism, thought to be WW2 surplus. Some people upgrade to modern because it is said to be a little better. If your top port view shows a correct image, left to right, then it is an original Amici. If the view is reversed left to right, then you already have a modern replacement.

3. No solar filter on your finder view. That tiny solar filter covers the port on the bottom of the OTA, and fully protects the Q. Be very careful using the solar filter you posted! If you are looking through the EP and flip the wrong lever you will get a nasty surprise. Supposedly Johnny Carson (of the old Tonight Show) owned a Q and got a brief blast, and complained. Thus the finder EP was invented and installed on all newer Q's.

I would think it could be much more difficult to find the sun without a protected finder view, but I never had to try.

This is such a huge eye safety issue that if you intend to do a lot of solar viewing you should maybe consider it, even if it means "devaluing" the collectable value. And one reason I previously suggested the old scopes are not ideal for use as a primary scope, but better as a secondary collectable kind of thing. Where it gets taken out for a ride every now and then like a classic car, but not used as a sole "daily driver". I have an original owner and still very stock '85 Mazda RX-7 GLS-SE, so I understand and think about that concept a lot

4. Your legs are push fit. Around 1982 they went to screw in. The old push fits are said to be more elegant, but supposedly they required hand matching to the mount because the tolerances are very tight. As a result, they might be very difficult to replace. Aside from the fact that replacements may not be onhand at the factory???

5. The cases now have real hinges, avoiding the problem you likely have that the "hinge" is brittle and weak, and may not take a lot of use now before it splits completely (??).

6. Your solar filter does not appear to be an off-axis design, but nor does it seem to be a full solar filter. I don't recall anything about that- just noticed yours looks different than mine and don't recall "almost full filters".

7. Contrary to what I said, checking some notes from the Yahoo group, your tube might be aluminum or synthane. Synthane may have been used from 1957-58 on some, not all of those years- one of those things that is unsettled due to lack of data on specific samples. Not sure from the pics you posted but I think aluminum??

8. Your dew shield is, or was, hand etched with the stars. Moderns dew shields have the star map silk screened on, with no etching.

9. There are a total of 4 different logo disks known, plus the 50th anniversary model disk. You appear to have the 3rd disk, which was generally put into use around 1962-3. Various 1955 models have been reported with disk #1 and 2, but I think there could be some uncertainty about possible replacements at some point in time?? (that was why these things were studied quite a while back on the yahoo group). But it suggests your unit is not fully pristine, as best I understand those things. You could spend a few evenings searching the yahoo group for discussions about all these differences, and the relative confidence anyone has in deciphering them.

10. Your OTA is a bit shorter than modern OTAs because the central silvered spot is on the outside of the corrector, where modern optics have the spot on the inside. The change resulted in a longer tube, which creates issues with dew shields and the case in the rare event that the optics are replaced. Also requires a new tube, of course. It is thought that the original spot location had to do with avoiding patent infringement, which later expired, allowing the supposedly slightly more optimum inside location.

There may be other differences, but the one resource I have handy lists the above.

I do not ever recall anyone having trouble getting their repair history... being told it is "archived offsite". Interesting. You might want to press them to retrieve it because I think it is important to know before you even start planning to service it.

P.S. #11 - modern Q's did not come with a cat

Edit, on a more serious note, from memory, another difference is that the finder mirror mount for the very early Q's may have been different maybe not quite as robust as modern Q's. I seem to recall the early Q finder mounts were just bent by hand to align it to the optical axis? (don't try that now, just thinking out loud). If you can get sharp closeups you might try photographing that.

A 12th difference... early Q's have a narrower field of view and a correspondingly smaller rear port. My memory is bad on this, but the increased FOV may have been coincident with the move of the spot to the inside of the corrector.

This is important to know because any accessories you buy that thread to the rear port, such as camera coupling plumbing, would have to be threaded for the old style narrower port.

The narrower FOV *might* also adversely affect the use of wider angle eyepieces, such as the 32mm Brandon EPs, or even something wider, should you ever get the top eyepiece port adapter updated. (Might vignette) But you would have to research that because my memory is not clear on these details.

You appear to have a "spare" eyepiece adapter. If so, the installed adapter may accommodate Brandon EP's and/or standard 1.25", although you do not appear to have set screws in the EP adapter to hold a standard EP. I am not familiar enough with the various EP adapters to figure it out from the various images.

You have a modern base, not synthane, which makes sense with the serial# change. Most likely drive motor parts were replaced?

Maybe someone with an older scope with push-fit legs can answer this, but I think there should be a set of plugs for the base, to plug the holes for the two tripod legs that fit into the side of the base when the legs are removed? Not necessary but I was curious about that. The images I've seen of early Q's with push fit legs appear to have a very different plug than my 1996 with modern screw in legs.

You have a pair of "thumb screws" in the image- any idea what they fit? OR maybe they are the base plugs?

You seem to have two solar filters, one off axis, and the other filter in the box, which I assume is a slightly less than full solar filter?

Not sure what the large round flat thingy is on the left of your accessory image. Unless it is a lens cap? I recall the earliest OTAs were not threaded for a lens cap so it did not come with the modern screw on metal lens cap. But again my memory is failing me on that accessory.

You should have a 2 pin power cord that plugs into the base. If not, Q can sell you one, or it is said to be a fairly standard plug in AC cord.

Your last image appears to have a finder solar filter, which was probably added during a service. And the new finder mount, which I think would be required for the finder solar filter. As I recall, Questar really wants the old scopes updated with the finder solar filter, for liability reasons (and I suspect they really care about your eyes).

So you have likely had a number of updates already done to the scope, which mitigates most reasons I can think of for not sending it in for a service (unless it just doesn't need it, which is why you need the details on the service).

Looks like you've got a full-aperture solar filter (the large "mirrored" filter) in its own protective box - both good. Probably best to store the close-focussing diaphram separately so it doesn't scratch the solar filter.

It looks like the metal may have been painted with enamel but I am not 100% sure about that. I do have the cord to plug into the scope. I have two eye pieces that came with it. A 40X and 80X which screw into the the scope. Near the bottom of each eye piece, there are gradations (2, + 0, - 2). I have never seen this before but I don't have much experience. The two thumb screws, screw into the bottom of the scope and may hold the legs in more securely. I have several wooden pegs that fit into the legs. Pretty neat looking.

I suggest putting some leather treatment on the outside of the case. In the UK I'd recommend Leatherfood (which is a paste) but not sure if that is available in the USA. Does anyone know what the company recommend? You want something not too oily because you don't want the oil or it's vapours to creep onto the scope. In the early cases the leather forms the hinge so make sure you treat that area especially well.

Edit: That's Chelsea Leather Food. Looks like it is also available in the USA.

Jack,

Where do you live in Maine? There is a major collector of Questars that lives in Maine. He has what is believed to be the largest collection of Qs in the world. He is also the person that has composed most of the papers on Questars and his reports are a major part of the Yahoo Questar Group's files. He opens his website in December for about a week for viewing. You need to join the Yahoo Questar Group so you can access these items. There is an odd thing about your serial number. The first production Q SN was 50 and the first year of production was 1954. Yours is serial number 104 (that means yours is number 55th Q that was made) and Questar told you it's poduction date was 7/1/1955. I wonder what the orginal serial number was before the rework serial number was placed on the bottom of your Q. The orginal bottom was black and would have had a serial number of 5-104 if it was made in 1955. I have seen a list that may show serial number 104 was made in 1954 and would have had 4-104 on the orginal black bottom plate. It also shows that SN 104 may have been the last one made in 1954. This might mean they made a production run of 55 Qs in the first year and did not sell yours until 7/1/55 (this has happened in a number of years). When you call Questar for the information on what the R on your SN means ask them for the orginal SN. The reason this information is stored off site is that Questar is now owned by a larger CNN company that is in another state.

The last picture appears to show a finder solar filter control knob. I wonder if the finder or maybe the whole control box was replaced.

To NeilR: remember that the solar filter on the early Qs is not a screw-on and the rear axial port was a smaller size (.95" -v- 1.2").

I have some photos of SN 114, which is 9 after yours, and appears to be pristine in all ways. In excellent shape and no indication (to me) that it was ever modified. It has the type 1 earliest logo covering the Dec bearings.

That scope has a bare metal control box. The image suggests the control box is "rough", meaning obvious, but I think it was shot with flash in a way that exaggerates that. It may look much smoother in normal light.

If the control box is painted enamel, then it was probably replaced when it was serviced. I recall that the early Q control boxes were not painted. But like many of these changes, it is not clear to me when the painted enamel started.

Comparing the images, I see that the installed EP adapters of your scope and #114 are similar if not identical.

Do the two "thumb screws" have O rings around the wide end? I think they also serve as plugs in the two leg holes. Try it. The O rings should keep them in place. When screwed into the base they act as car window holders. Some early ads show a Q hanging on a car window OUTSIDE the car. That feature was dropped, I guess when they went to screw in legs and changed the plugs.

Could you post an image of the 3 legs, as close as possible to the end that inserts into the base? I've never seen an image of that end of the push fit legs.

I think the silver cylinder coupler in your accessory image is an old camera adapter, sans the extension tube. Probably original. The black adapter may be a later camera coupler? Do both of those adapters have the same threading size on the narrow (resting on the table in your image above)? Does either thread into the optical tube rear port?

Bill,

I live in New Hampshire near the Maine border. I have sent a request to the group but the membership is still pending. Hopefully, it will get approved so I can look at his material. I will contact Questar again and see if I can get additional information on the scope. You have all been such a big help and I really appreciate it.

Jack

NeilR,

I will take some additional pictures tonight of the control box and 3 legs. I will also check out the "thumb screws" and see if they fit into the leg holes.

Oh, before I forget, the cat loves the case. Every time I get the scope out he jumps inside and makes himself at home

Are you kidding me about the ads showing a Q hanging on a car window OUTSIDE the car? Wow...now that is a confidence or a "leap of faith" that the scope won't fall off. You have provided such a wealth of information.

Best Regards,
Jack

I have a photo of the bottom plate of #114. The S/N is indicated as "#114". It is my recollection that the year digit was not incorporated in SNs of the earliest Q's. So in this case the '8' is sort of a Red Herring.

The original synthane base plate of #114 has "#114" above the central polar axis leg hole, and below the hole 3 patent numbers are listed, and below that "115V. 60~ A.C.". This is why I am quite sure Jack's base plate is a later update, aside from the fact that it is aluminum and not synthane.

The year was probably added to all SNs sometime in 1957. The earliest record I have is 7-349. SN 246 does not have a date. SN 284 is inscribed "R-2-284" with a notation that it was rebuilt in 1962. It still has an AC motor.

SN 198 and 246 apparently has no year in the SN but both now have a solar filter, 198 was added in 2005. So adding a solar filter did not warrant a "rebuild" added to the SN.

SN 123 was retrofitted with a Power Guide I in 1995, but the list has no indication that the SN was changed (which could be an omission!). I have a PGII in my 1996 Questar, an early version of PGII, and my Q has a flat base. Later versions of PGII require a bevelled baseplate to accommodate a slight increase in size of the drive motor.

If I ever needed a replacement motor I would have to have the base plate replaced, and also would need a new case. I actually have a strange problem with my PGII but I put up with it because I never wanted to go through the expense of all that. But the point is that *I THINK* some of these remanufactured SNs have something to do with base plate replacements required for drive motor repairs and updates. But maybe/probably (?) not all. Most of this is all in the Yahoo archives but I am too lazy to start down that road right now

I am aware that the earliest Q's do not have a threaded barrel, but I have never had such an old Q in my hands and don't know quite how they dealt with filters and caps. I assume it is some sort of press fit.

I previously mentioned that the finder solar filter appeared to be installed. It is my understanding that that can be added to the existing solar filter mount. My original suggestion that the finder cage was substantially different is likely incorrect, due to what I see on photos of #114.

I think the control box was changed because Jack's photo vaguely suggests it is enameled and I think he is confirming it. If it was changed, it is possible that it is the same control box used on modern "wide field" Questars and has that 1.2" port. It is very possible that the owner that had it updated also ended up with two camera couplers, which is why I asked about the diameters.

Jack could help get to the bottom of this by unscrewing the rear port cap and measuring the diameter of the port hole. And also measure the diameter of the narrow threaded end of what I think are two camera couplers.

My most recent "list" is the current list from the Yahoo group, listing slightly over 100 Questars, with SNs and major evolutionary features and options that the group was interested in. Plus 6 field models. There are five "1955" models, or at least that is the year indicated, the first being 114 and the last 230. the next SN is 246, indicated as 1957. I would assume that the years came from inquiries to Questar as to manufacture or sales date, or maybe paperwork that often accompanies older scopes. Over the years there have been discussions of other older Q's, many listed on eBay but unfortunately I did not download images and take notes. At times like this I wish I had! Your "list" seems to be different and I would be curious of the source. I'm not familiar with anything as specific as you mention. A search of the Yahoo archives might be fruitful. I also have the complete archives of the major-domo group that preceded the Yahoo group.

Jack- I was not kidding about hanging the Q on a car window. The 1960 Questar "White Book" is a very extensive 35 page marketing booklet that is almost, but not quite, a manual in itself. Page 9 includes a photo of a Q hanging on the outside of a car window, with the door open, with the following caption:

"It takes but a minute to attach your Questar to the great mass of your car. Just pull out the two front leg plug holes, screw them into the base casting, and hook their wide heads over the lowered glass. Many modern cars are so flat on front and rear decks that Questar may be used from them without attachment"

The car window is cracked only 2 inches or so. From the early years, Questar has stressed the utility of the Questar for birding. I am a birder myself, and have used mine on occasion, although I shoot with a 500/4 lens and tripod and don't usually further complicate my birding with a spotting scope. Plus I am too cheap to buy an erecting prism

I got the pdf for that booklet from the same gentleman Jack mentions. Among other treasures is an image of 18 Questars (14 fully mounted astros), all set up, on a desk top. And that was shot almost 7 years ago. It is a sight to behold . If you do not get accepted into the group within a week, let us know and we will try to tap a shoulder or two.

In following this thread, I was surprised that that the thumb screws/plugs were also to be used for hanging the telescope on a vehicle window, so I had a look on our older 1971 model Q. I noted that indeed the leg holes were threaded, but the coresponding holes in the base plate were not lined up. Perhaps this was intentionally done for safety reasons when the scope was serviced prior to our acquisition ?

Here are a couple of photos.

Mike- I just want to be very clear that I am not advocating using that "feature" (for Jack's benefit). It is clear that the feature was abandoned at some point, certainly by the time screw in legs were introduced, but I don't recall any discussion of why. Not that my memory is the final arbiter of 15 years of forum threads.


(1981 is the last year, on that 100 scope inventory, where push-in legs were reported. The first screw-in leg was reported in 1980. And one odd-ball in 1978 bought from Questar used, and may have been a bit of a Frankenstein. There are often transition years for features where old stock was partially used up, or whatever reason)

I do think it is helpful to understand the historical implications of these things. Caveat Emptor.

That probably just illustrates my intuitive grasp of the obvious, but just in case

Your observation is very interesting. However, I have to ask- was it that way when you bought the scope, and were you the original owner and/or certain you were the first to get it serviced?

I ask because it is not clear to me how that could be changed without replacing the plate. The two "window mount holes", and the various base attachment holes, and the AC plug hole all have to align just so and could not be changed without drilling new holes and leaving others uncovered. And that brings up the issue... are bottom plates ever replaced with the same identical serial# re-inscribed to the new one? I ony vaguely recall this issue coming up a long time ago.

What I am saying is that it is *possible* that the scope came that way from the factory, and by 1971 the factory might have decided not to support that feature. Perhaps in response to receiving too many dropped Q's? But in any event raises the question of why the "useless" holes would even be put into any plate if the intent was to eliminate window mounting. IOW I am confused

If would be interesting to hear from others that have later push fit legs to see if their holes line up. Especially any scopes that are known never to have been back for a service (which may indeed be rare 40+ years later).

Hi Neil,

I would not advocate using "that" feature either. I understand we are the third owner of our Questar. It came with the old style 40x-80x and 80x-160x marked eyepieces, so I contacted Mr. Reichert to order a new diopter adjustable eyepiece holder. He told me that the scope had been serviced in November of 2010. The base plate was in its present position when we acquired it.

The four screws holding the base plate on are equidistant, so in our case, rotating the baseplate 90* would line the holes with the leg openings; of course, I have no intention to do so.

Hi Neil,

The four screws holding the base plate on are equidistant, so in our case, rotating the baseplate 90* would line the holes with the leg openings; of course, I have no intention to do so.




But would that not place the oval shaped hole over the AC adapter in the wrong place? As I mentioned, that is why I thought it was not just an "assembly option" that a user could change by reorienting the plate, or an assembly mistake.

Not sure, as I have never taken the base off .

You don't have to do it. Just think about what happens if you rotate the plate 90 degrees. The AC adapter is now sitting under solid metal and unusable, and the oval AC adapter hole is over top of some useless place

It's what makes this strange, and why I was asking if anyone else with a similar era Q has the same alignment. The only thing that makes sense is that the holes were drilled in the wrong place and the assembler missed it since "window mounting" may not be something they are thinking about.

With a sample size of 1 we can only speculate...

I see there is a photo on page 22 of the Questar instruction book, showing that the AC adapter hole is located between the legs, the same location as in the photo of the Questar belonging to Jack.

That suggests that your drive motor is misaligned by 90 degrees, because your bottom plate and Jack's bottom plate appear to me to have the same alignment of all the holes.

Never having disassembled a Q, or even taken the bottom off mine, and not even having the same setup (I have PGII) I can ony assume that the internal parts can be aligned anywhere inside, more or less? Maybe someone who has can answer that question.

Is that really a solar filter in the wood solar filter box? It is labeled "variable aperture" and "use at less than 25 ft" and looks to be in a state of decay.

I Have both # 198 and #7-349 and the early Questar had no year indicator. If fact at least # 198 does not have a way to attach a tripod easily. I bought a separate plate to mount on the bottom of the base of the Questar so I could attach the Questar to the tripod. The early off-axis sun filters did not screw in I am told.

We've covered this already, and decided that it's a close-focusing diaphragm currently in the process of scratching the full-aperture solar filter behind it. Read the bit of paper in the box.

State of decay? The solar filter has a reflective coating. I see a state of decay when I look in the mirror in the morning, too, but it's not the mirror!

The screws visible on either side of the AC connector indicate to me that is attached to the bottom plate, so will rotate with the bottom plate. To find out if the other innards (wires, motor, etc.) will allow you to do this, you'll have to talk to a man with a screwdriver.

...or a hacksaw. Here's a pic from the cutaway thread.(Thank you Darren Drake.) The motor is bolted to the ceiling of the base. The power connector (missing from the cutaway but you can see the holes) is bolted to the floor of the base. Looks to me like you can put the base plate in 2 or 3 positions without the electrical connector interfering with the motor.

NeilR,

The two "thumb screws" have O-rings around the wide end and do fit into the two leg holes. The silver cylinder coupler and black adapter have the same thread size and thread into the optical tube rear port. I still have to take the pictures of the 3 legs and hope to post the pictures later today. I contacted the "Mother Ship" again about the service records and Jim stated that "I do not have any way to excess the old files." Also I asked about the serial number and Jim said that the number should have always been the same except of the "R" was added later.

Strange, that is at odds with the image I have of #114 and what I have read otherwise over the years.

I don't think a single negative result from an enquiry marks the end of an era. In the single instance that I've dealt with Jim R. at Questar he was very helpful. The posts in this forum imply that he has been so helpful for so long that it is almost taken for granted that he will do the running around, gratis, when asked to do so. However, the Q records go back 60 years, and some of those for the older models might be archived offsite or otherwise require extra time to dig up. It is a great courtesy of Jim to supply the information he does, but I don't think he should be expected to automatically research the service records of every used Q that gets sold. Can you imagine what your local car dealer would say if you asked him to find and give you, for free, the service records of a car that you just bought from someone else?

The socket head screws on our O-ring plugs looked unfinished, so it was simple enough squeeze on some plastic caps such as bobs knobs uses to make the plugs easier to grip, and add a nicer appearance.

Jack, the tubing on your tripod legs appears to have a much heavier wall thickness compared to our 1971 model.

Edit: Ahh, that appears to be a camera issue, my camera seems to enhance the actual size also; please disregard this post.

Thanks, Jack. It cleared up some confusion I had as to the design.

Somewhere on the Yahoo group there is a discussion about the assembly of the push fit legs. Supposedly someone had a pile of legs in front of them. For each mount different legs were picked from the pile to see which fit the best.

If that is true, then each leg would have to go in a specific leg hole, since the tolerance would vary by leg hole? I'd have to go back and find that thread to see if that was addressed. Just a factoid from a long ago discussion.

Hi Robert,

Thank you. I didn't know very much about Q's until getting this one. I have enjoyed looking into the night sky for most of my life (naked eye or cheap pair of binoculars). I showed my children most of the major constellations and even convinced one of my daughter's to take an astronomy class in high school. Unfortunately, she didn't enjoy the class too much. Most of the class focused on "theory or book knowledge" instead of taking them outside to learn the constellations and how to use a telescope. To redeem myself (when she comes to visit), I have taken out my Dob and shown her Jupiter and Saturn.

Yes, learning the history of the scope and the previous owner has been very fascinating and educational. I haven't had the chance to use it yet. Either work has gotten in the way or the weather has been very uncooperative. I must say that I am looking forward to using it. Have a great day and clear skies to you. Merry Christmas!

Best Regards,
Jack

Lol.... that's how it is with kids. When Jupiter was visible in the morning, my daughters would want to look before school. It was nice. Our youngest is 11 TODAY! She's having a party.
Yes, I was imagining what it would be like to buy something and then find out it and the owners history. It would be quite interesting.
Good luck and Merry Christmas!

Kids...they certainly know how to make us laught! I hope that your youngest had a great birthday party! Once I get a chance to use it I will post my first impressions on the scope. I will also take the advice of some of the posters and use it during the day to get my feet wet. Learning to do the polar alignment might prove to be an interesting exercise

Bill,

I just ordered one of the adapters from Questar. They are indeed $85, as you said. I forgot to ask when I ordered the adapter, will I be able to use the Brandon screw in eyepieces with the adapter(circa 1978)?

Thanks, Tim

It literally takes minutes to set up and break down. Not to mention if you're using the supplied legs on a table top (I use a hefty picnic table) you can do it all comfortably sitting down. Atlases, iPad, etc. all within easy reach on the table! The viewing experience is so seamless and effortless.

Wonderfully crisp views. Only 3.5 in, yes, but I can count on one hand the number of times seeing provided me with optimal 8 in views with my C8.

Of course the C8 beats it on clusters and galaxies but once again my city skies are so light polluted that lunar, planetary, and double star viewing is what I do anyway. Q rocks here.

I must say I have never yet taken the little Q to a really, really dark site. I'm curious how it performs there.




One of the darker sites I've experienced was at the edge of the Everglades in an undeveloped real estate development, formerly used by the SW Florida Astronomical Society for their star parties. Observing M46 one night, I spotted the planetary nebula NGC 2438 (confirmed by other observers at the site). This planetary is rated at magnitude 10.8.
