TASCO 7TE-5 Refractor
      #1613911 - 05/19/07 06:40 PM

Hi All!I have one of the best 60mm Refractors ever produced by TASCO.I was out last evening with the Model 7TE-5 ,and while looking at Jupiter I was amazed to see the disks of the four largest moons,Ganymede,Europa,and Callisto.This instrument has a focal length of 1000mm and I viewed using an 8mm Televue Plossl eyepiece.This is the first time ever seeing this with a 60mm.Is this telescope as good or better than a comparable Unitron?

At f/16.6 that little Tasco should be the equal or better for sharpness and CA than many other 60mm scopes including Unitrons.

Welcome to CN.

Actually, I'm surprised you've never seen the Galilean moons with other 2.4" refractors. I've seen them in very small binoculars and my grandmother's vision was such that she could see them naked eye (positions verified with telescope after she drew out where she saw them). What brands were you using before this 7TE?

If I can be so bold to sum everyone's opinions here, the consensus seems to be that mechanically (design, fit and finish) the Unitrons are superior to the Sears and Tascos of the day, with exceptions. Optically, being a Royal Astro product, the Tascos were comparable. In general, the 7TEs have a good, solid reputation.

Collectability, there is no comparison...2.4" Unitrons go for 2, 3 and 4 times what 2.4" Tascos go for. (I would not consider them that much better, though.)

Yes, when my Dad first discovered this interesting fact about his Mom, he was showing her Jupiter through his little telescope. He was about 11 or 12 at the time. She kept looking at Jupiter through the eyepiece and then looking straight up, then back to the eyepiece again, all the time with this confused look on her face. Finally she said that there must be something wrong with his telescope, because the moons were backwards in it.

I've read several accounts of "nekid" eye view of Jupiter's moons. One technique is to use the edge of a wall or building to mask the disk revealing the moon(s).

All these scopes from the late 60s and 70s have good and bad lenses I have one Tasco 60mm that is very good, Clean star tests and sees pretty good Compared to a 4 or 5" scope. Then I have another that is also very clean glass and it sucks. There both culminated and set up right but I think the second ones lens is turned at the edge because if I reduce the aperture it gets way better. After getting the 1958 50mm Nikon and looking thru it last night all these mass produced scopes fell to this scopes optics they are incredible. A friend over mine has an 80mm Nikon and said it is the best glass he has ever seen and he has 5 observatories in his back yard and over 70 scopes. This same friend sold me a 1954 2.4 alt. az. Unitron and he said its optics are perfect. It is coming Tuesday I will let you know if it is as good as the good late 60s Tasco 7TE-5 But being from the early 50s I bet it is better!

So I wonder how many 2.4 unitrons you have laying around that you dont use because your Taco seven is so much better.




If I may, I don't think Barabino was saying his Tasco was better than a Unitron, merely that he liked what he saw, and was wondering how it matched up to a Unitron.

I must say that the earlier the optics the better the scope. Thats the case with the old Selsi maybe aka unitron in my avatar. Even with the dirty optics it is far superior to my Tasco. But I feel alot of this has to do with the accessories used that come with the scope, like excellent eyepieces or more modern high end Televues that some purchase to give better results. Also technique and sky conditions can play a big part.
I have always had luck water metal detecting. I was asked by several people why I produce 3 times the gold finds with a basic water unit in comparison to people who use extremely high end equipment.
My answer is always patience, knowing your equipment and how to modify things to produce the best results.

I agree with John Siple's July 2003 review where he says the 7te-5 is "One of the finest 60mm. telescopes
ever conceived of."

I take it you meant that the moons were not just visible but visible as "disks" ? That would be a significant visual achievement.

So you have a winner !

Hi BarabinoSr,

These venerable Tascos were often very good scopes. Your experiences are frequently shared by others of us who are blessed by owning one of these fine scopes!

I think this telescope made by ASTRO OPTICAL IND.CO.,LTD, Japan.
TASCO, SWIFT .etc.Those companies were trading merchant, sold Japanese telescopes around 1960-1980.
I'm japanese telescope's mania.

Well, hello Stranger. Welcome to CN.

Yup, from what we've been able to determine here, the genesis of the 60mm and 76mm Tascos was indeed Astro Optical. There is a PDF version of Astro's catalog floating around amongst the members here, but your post looks like its straight from Japan. Do you have a copy/PDF of this?

Good to meet you and thanks for the post.

Hello trainsktg.
yes. From Japan direct
I am a beginner in this system.
In addition, I am not good at English.
I came over in this site becouse I wanted information of vintage telescopes.
I have old telescopes and catalogs.
But I do not like that data become too popular by the reason of a copyright.
I want you to forgive me.
I will offer information to this site in future.

I used a spray carpet cleaner to remove the yellowing on the tube. I also use a product called Ballistol to lube mechanical moving parts. Its bio-degradable no carcinogens no buildup. Try it. Another fine German product safe to use on anything including plastics, wood, steel. Invented before 1900 for use on firearms.

Your Tasco 2.4-inch equatorial refractor has an objective lens supplied by Carton Optical Co. of Tokyo, Japan. Unitron also used Carton Optical as a subcontractor for many of their 60mm objectives during the 1960s and 70s. Therefore comparing Unitron against Tasco is essentially comparing Carton's 900mm focal length objectives (Unitron) against other Carton objectives with a longer focal length of 1000mm (Tasco).

However, Tasco's 1000mm focal length objectives were some of the best ever made for small refractors by that Japanese company. Optically figuring is consistently good to perfect, so an owner of any vintage Tasco Model #7TE-5 is virtually guaranteed to get a superb performer.

Apogee, Inc. of Union, Illinois had a huge surplus stock of 1990s 2.4-inch Carton objectives with a focal length of 1000mm. They were selling these in an aluminum cell for about $20 several years ago. I bought three or four of them for testing. The coatings on the older stock #7TE-5 objectives were slightly better, plus the metal foil spacers between the crown and flint elements were of a higher professional quality on the old stock used in the Tasco refractors.

As an experiment I took the crown element from the newer 1990s Apogee stock Carton lens and directly substituted this for a crown element on a spare 1960s Tasco #7TE-5 objective. Star testing showed absolutely no change in optical peformance. Alternatively, I took the flint element from the newer 1990s Apogee stock Carton lens and substituted this for a flint element on a 1960s Tasco #7TE-5 objective. Again, no change in the diffraction image, contrast, etc.!

This indicates consistent quality in optical figuring from the 1960s through the 1990s; extreme quality control! I don't know if Apogee, Inc. has any more of these Carton/Tasco 2.4-inch diameter, 1000mm focal length objectives--many schools and individuals were purchasing large lots of them for solar scopes because of the longer focal length and superior performance.

Great replacement objectives for that damaged Tasco lens!

What is the R number for the Tasco Model #7TE-5 equatorial refractor as displayed in your Japanese telescope advertisement? Royal Astro Optical Industries Co., Ltd. identified all of their refractor telescopes with an R number in their catalogues. Based on objective lens diameter, it should be R-60, 61, 62, 63,...etc.? Many Tasco collectors would love to know this number!!!

Hi Gary!

Thanx for starting this thread. I am waiting for the second 7TE-5 to arrive so I can piece together the best from both scopes.

Observing with this scope is very impressive. I did not think I would get such high magnification (240x) with a 60mm lens (Saturn was amazing). This has been a real turn around for me about my opinion of long refractors. I'm hooked!

I just hope I don't end up like everyone else here spending lots of money on old dusty scopes. Well gotta go - I have to bid on a dusty old scope on Ebay....

Your knowledg for japanese telescope are splendid.
Information of Tasco admires over our far.
I think tripod and draw-tube are style that Astro optics uses well.
Mount style is used by carton and others, We say this style, kojima-siki, designed by syusuke kojima, he is founder of Astro optics.

Galakuma,
Welcome to the Classic Telescopes forum! I hope you visit here often as I think we could learn alot of information from you. I also hope that you can learn from us as well. Don't worry about your English. It is better than my Japanese! Please ask others in Japan to visit here as well.

Dear Sir:

We graciously thank you for the excellent image of the 60mm refractor telescope (what is the R designation for the instrument with the 1000mm focal length?). Does your literature show the 90mm version (focal length 1400mm) of the same refractor? Please look at the listing in the classic scopes forum posted on 05/15/07 by Habsburg8. It is titled "Rare Sears 90mm from 1970-72."

If you can locate the catalogue image of this rare 90mm refractor can you present it for our group to view? Please place/post any information that you might have about the 90mm equatorial refractor in your catalogue literature to the "Rare Sears 90mm from 1970-72" discussion.

This refractor should have an R-90, 91,..., etc. designation by Royal Astro Optical Industries Co., Ltd. How rare is this particular 90mm refractor telescope in Japan? It was imported by Sears and sold in the United States for only a few short years.

Just a note to inform all that I have seen the satellites of Jupiter hundreds of times down through the years.I am the records keeper for the Vega Sky Center which dates back to August 1970,as compiled yearly in our annual VSC Astronomical Journals.But the fact is I have seen the discs during previous observing sessions its just that the satellites' discs were easier to see in this particular scope.BTW I also viewed two of my personal favorite double stars on last evening:Albireo(Beta Cygni)and Epsilon Lyrae .The color contrast between Albireo's component stars is very pronounced -yellow and bluish white,and both stars in Epsilon Lyrae were resolved-colors white.Just enjoyed the views.Gary

Ah, the key word...'discs'. I should have known. That is a pretty good feat in a 60mm regardless. Your latitude helps some, I suppose. This chump chose a house at 46N, under the jet stream, near a volcano, yada, yada.

Thank you so much For this information, again Galakuma!!!! My 1961 60mm Swift model 839 was also designed by Mr. Kojima, but other than that, I could not find out who manufactured for Swift. You are very generous to share your knowlege with us.Thank you again!


Bam, that is one glorious Tasco!
....and Preston, welcome to the club!

How about if we started a thread to compare photos of Kojima-siki refractors. It would be interesting to see the evolution of this fine family

Hi Bill!

How does this product work in very cold temperatures?

Do you also use it on your GEM mount?

Gary,
That is a Tasco made clock drive that was designed for the 7TE-5. The motor is the same as the 10TE/15TE but the attachment brackets are different. Have not seen many of these and esp. not the 7TE-5 bracket....

Well,

I now have both 7TE-5s in my possesion. The first mount is totally dissasembled on my work table and going through a 100% refurb. I did a quick regrease and new felt with the second mount and at least I can take this one with me to Texas if I don't get the time to finish the refurb on the first mount.

I'm very pleased with the objectives of both scopes. The first objective got a small clamshell chip when it was shipped to me but it does not affect viewing. I learned my lesson and made a special objective cell box that I constructed and shipped to the seller of the second scope. She was kind enough to send the objective seperately surrounded by LOTS of styrofoam inside the box.

Does anyone understand the serial number sequence for these Tascos? I want to find out exactly when these two scopes were made.

Here's a picture of the scope I'm using now:

I have a chance at picking up a 7TE-5 for $50.00. It is in ok shape though no where near great shape and only comes with one eyepiece. The rest along with the rest of the accessories were lost with the case. Still, mount and tube assembly appear to be good though dirty. How much are these worth? I know they are excellent scopes but would it be worth my waiting for another to come along? Keep in mind I will likely have to drive about 100 miles to get it. Thanks and feel free to PM me on this if you prefer.

They seem to be going in the $200 range at the high end. As long as the one you are looking at is straight and needs just a little cleanup, $50 is very reasonable, even missing all of the extra goodies.

Hi Darren,

I would recommend getting it.

In my case, I purchased two for around $100 each. As a result I can pull the best components together to get a really nice scope. There are always the hidden items that pop up. Focuser gears that are worn, stripped screws, missing hardware, bad eyepieces, etc.

If you buy more than one you can always resell the parts you don't want to keep. I would strongly recommend keeping any extra objectives you get as this is one of the VERY few 60mm scopes with a 1000mm focal length. Most are 900mm or 700mm.

Or you can sell the objectives to me!

Hope you get it - it's a great scope and there are still a few sources for .965 eyepieces including those that come up for sale on Astromart.

Hi Preston!That's a great looking scope !You've done an excellent job in putting that one togather.Of late I've been performing some minor maintenance on my unit,including greasing the moving shafts on the mount and touching up work.My next improvement project is to flock the inside drawtube.I've noticed minor internal reflections especially when viewing the moon,and that can easily be corrected.Also I am still looking for a suitable clock drive unit to fit this telescope.Looks like skies might be ok around here tonight.I plan to observe.Clear Skies Gary Barabino Sr

I just won the EBay auction for this Tasco 7 TE-5 and I am now waiting for the scope to arrive. Link It looks to be in great shape and complete. Is it the TE-5 that won't accept the 1.25" screw on adapter? My Tasco 8V's drawtube is threaded to accept either the .965 or 1.25 eyepiece holders and I was hoping to be able to use the bigger eyepieces with the refractor. I hope the tripod is better than the one that came with that Towa-Moncom-Tanzutsu I put up for discussion/disection on the Classic Scopes forum a couple of months ago. Were the mounts and tripods on these Tasco scopes sourced from Royal Astro as well as the objectives?

Hi Starpoke,

A great way to use your 1.25" oculars on your 7te-5 is to get yourself a 90 degree .965 to 1.25" Hybrid Star Diagonal. AgenaAstro Products has them. The cool thing able this diagonal is that it can also be used on refractors with standard 1.25" focusers as well. The price and quality of the unit is very reasonable. Hope this will help. Look under the "Resource Links" on my website shown below for the AgenaAstro's website link. Manish (the owner) is great to work with. He is very customer conscientious.

Hey Starpoke aka Glenn,

Didn't see a first impression or first light report on your new scope. Did you get a nice one? I was also able to snag a 7te5 ten days after you, (on eBAY too), and mine appears to have not been out of the case more than twice in the last 40 years or so... (Maybe just once for the eBAY photo). A little buddy for my 10te to hang with . Mine even came with part of an article written in 2004, (most likely by John, aka Habsburg 8), extolling the virtues of vintage Tasco scopes. Lucky for me the seller evidently didn't read the article before setting the BIN price!

In 1965 and 1966, a friend from school and I would occasionally pester his dad into taking us up to some spots near the Mt Wilson Observatory, (Charleston Flats and Chalao Flats), for overnighters with our telescopes. The first excursion was to observe comet Ikeya-Seki. I had a Tasco 9te5 (60 X 700 alt/az) and Bruce had what I now realize was a 7te5. His scope was way cooler than mine. In 1966 I had graduated to an Edmund 3" equatorial refractor to bring to our mountain observation site, while Bruce had his 7te5. His scope was still way cooler than mine.

Yes Keith. Congratulations on your nice score. Mine is nice but not pristine. It actually has been in my greedy hands since Tuesday but I didn't get it set up until last night when I finally found the missing finder bracket in a misplaced piece of wrapping paper.
The sellers were very anxious to pack it well and I now have a small water tank heater size box full of popcorn, paper, foam rubber, and even Xmas tree flocking in my basement. The sscope box has laminate damage to the lid and is missing one of the lower styrofoam inserts but other than that it is, as far as I can tell, complete as originally shipped.
After I got it set up inside it was twilight and Jupiter and Venus were near the edge of a nice big sucker hole but diner had been announced so I hoped the sucker hole would stick around and went to eat. Of course solid clouds were waiting for me but nevertheless I lugged it out on the porch and pointed it over the rail at a porch light across the valley. I could not get the finder aligned and the wobble and shake as well as the darkness of late twilight made it impossible to use terrestrially. Is there a way to tighten up the legs at the base of the mount so that the whole assembly doesn't twist when you try to adjust azimuth?
I just left it out there for a bit while I started a mental list of work to do--fix the box, get the finder straight, lube the mount and adjust the focuser so I don't twist the scope out of alignment every time I try to focus.
After a bit I went out again and the moon was near the zenith and visible through thin fast moving clouds and was occasionally completely free of cloud cover. Moved to a better spot, got my observing chair out and proceeded to aim for the moon. I got a quick glace or two with the H 20mm so I went for the 0.965 adapter and the TV 26mm Plossel. At 40 power the half moon was crisp, and clear in the center of the field with reasonable detail near the terminator, probably as good as the atmosphere allowed.
Tracking was difficult as the slow motions were very stiff. I almost tipped the tripod once when I gave the dec. knob a smart twist.
The 12mm Brandon seemed sharp but I couldn't get it centered but amazingly I got a mountainous chunk of the terminator centered with my 4mm burgess planetary. Rats! I couldn't hold it in the field and focus at the same time. 250x was really soft but I don't think that is a fair indication since that was with the scope focused for the 12mm. Brandon. I think that if I can get the adjustments right and the mount steady enough that it will be rewarding to use.
I am glad this thread is still alive and being resurrected on a regular basis. I learned how the parts are supposed to be arranged and was able to reconstruct the packing for the missing styrofoam insert. I learned a lot about the scope and its quality heritage and have learn to respect at least some Tasco scopes. Now for some pictures:

Glenn,

I'm jealous, I didn't get ANY popcorn with mine. I did get a couple of really dirty boat seat floatation devices packed around the case that the seller obviously wanted to lose somewhere My wood case is delaminating as well. I think if you know stuff about wood you should start a thread on box repair. If you're not into restoration carpentry perhaps Rich (Woodsman) could jump in. So many of the cases are peeling if veneer, or cracked and split if built of "real wood". It would be great to learn how to save some of these vintage boxes.

I didn't get much time out with mine either. A little on Friday night. It was freezing foggy cold so the objective was quickly dewed/iced up. I'm surprised you were pushing this little guy to 250X already, but under my chronically poor seeing conditions 100X maybe 150X is my max. Whether I'm looking through my C-8, 102FS Tak, or a 60mm scope, images will soften and degrade long before 200X.

I think tightening the bolts that hold the mount to the legs will help with the twisting a little. Be careful not to overtighten though. The tripod wood could crack under pressure if real dry. Did you have the triangle eyepiece shelf attached, fully spread, and snug? I was pleased that the vibration seemed minimal with mine, but I wasn't trying to observe at 250X. I was also comparing the vibes to my 3" Tasco which really has the shakes.

My mount was VERY stiff in the cold, as was I. That 40 year old grease just isn't very lubricating anymore. I believe Preston wrote a "how to" on mount restoration and lubrication. Oh Preston.

You rang?

I have found the best grease to use on the 7TE-5 mounts is a synthetic from Dow Corning:

Dow Corning Molykote - Light

Use the light grease - not the medium for this application.

Expensive, but it's amazing grease.

I got a skinny "O" ring for the finder and with that jammed in the front of the finder, I was able to get it aligned with the scope.
The scope is in desperate need of major flocking I think. Before I fixed the finder when I was casting about for the moon I could tell I was getting close when I got this huge semi-circular wedge of bright light in the eyepiece field. I quickly learned to look on the convex side of the glare arc to find my target but it made a very awkward sort of finder.
Gary, this was not a minor glare. How did your flocking project go? Looking down the uncovered drawtube I can see that the inside has been blackened but it is still pretty shinny. The dew cap paint is a much flatter black on the inside. How can you uniformly blacken the inside of a drawtube? If I put black felt on the inside of the drawtube, wouldn't that vignette the view?
While I stew about that project, I can clear off the workbench and see what I can do to loosen up the focuser.
And then there is the mount. Keith, is the mount on your 10TE the same as the 7's? The dec. tangent arm is tricky on mine. It seems like when I get to the limit of travel the worm doesn't stop turning but just gets very stiff. Then when you wise up and try to back it out it just sits there for a while and then finaly moves. Backlash from Hell. Even though you can set it up as an Alt/Az mount, the limited movement in Altitude (dec.) makes it awkward to use. Setting the latitude for equatorial operation is also frustrating since the scale is so coarse and there is no stop or positive lock. I have to crank the two Latitude handles as tight as I can get them and then try to not disturb it while fighting stiff worms and shafts. Grrrrr.
All the great and convenient features available to us today really puts me in awe of those intrepid guys who routinely and successfully mastered these instruments and their quirks.
Clear skies all

Tasco 7TE-5 Mount Disassembly and Lubrication
Section 1 Dec Assembly
It has been too cold and cloudy here to do any viewing and rather than spending time lusting after stuff I can’t pay for on Ebay, Astromart and CN, I thought I would try to lube and adjust the mount for my 7TE-5. I had followed Astroboy”s instructions for de-glueing the CG5 mount and it still worked when I was done, at least for awhile, so I decided to go for it.

Thinking he first step would be to separate the tube holder from the dec axis. I peeled the felt back and tried to remove the 17mm nut. 17mm socket in hand I attacked the nut with a 3/8" ratchet. Ugggh! Nut did not want to budge. I retaliated with a ½" drive breaker bar and the tube holder in a 6" vise. Tlhat got it off, but to no purpose. The scope holder did not separate from the dec axis. I don’t know if it is a press fit, or just corroded but it was not coming off and I didn’t feel like fetching the sledge.
The other end of the dec axis looked more promising. There is a round retaining nut that is threaded for both the dec axis and the counterweight. Just like the CG5 mount there are two holes in the face of the nut for a spanner wrench.-on in this case a scrap of wood with two screws partly thru to do the job It seemed to start ok but bound up.. There is a small round hole in the housing and inspection showed that there are two set screws on opposite sides of the retainer which have to be backed off to free the shaft to unscrew from the retainer. After I got the shaft out the retainer would only come part way out Ah, the set screws were now sticking up too far so screw them back in and then the retainer drops out. After detaching the tangent arm and removing the worm from the housing I had all the declination assembly as broken down as far as it was going to get.

Section 2 R.A. Assembly

Like the Dec Axis, there is a nut on the top end and a threaded ring on the other end. The nut on top doesn’t want to come off either and can be ignored. The set screw for the ring nut on the bottom is in plain sight and when backed off, the retainer threads off . There are a number of fiber shims or washers that should be set aside to be replaced in the same order. They are apparently there to eliminate unnecessary metal to metal contact. Mine were all in good shape with only minor grease deposits.. The RA bearing and worm gear assembly come off together. To get at the RA bearing I had to remove the worm arm bolts and back off the center tension adjuster. Then the worm, ring gear and support assembly slid down the axis.
It was with some trepidation that I pulled the worm since I wasn’t sure I could get it adjusted back. I am glad I did because there was more dried and caked grease hidden there and the adjustment was straightforward.

Section 3. Final disassembly
.
The only moving parts left to investigate were the Latitude and Azimuth adjusters on the base of the mount and they were very straightforward. The latitude scale has no lock but there are two opposing handles that can clamp it reasonably tight. The latitude adjustment needs to be set at the alt/az position to fit the mount in the case and I found the adjustment for good polar alignment quite tricky.
The azimuth lock has a brass bias cut brass pin that clamps or releases the rotating surface. Only the lock and a flimsy tin plate {and gravity) secure it to the tripod head. If one mounted it upside down there might be a problem with scope security.
Fig 10. Azimuth assembly from below. The upper assembly comes off with the Latitude bolts.

4. The resurrection

The biggest challenges in putting it back together were lining up the brass sectors for the locks and adjusting the RA worm. Once the main bolts on the RA worm arms were tight, the middle tension rod seemed to control the mesh of the worm. Another adjustment would be setting the run out on the worm by loosening the worm nut and moving the adjusting screw in or out to take up any slack but that is best down with a scope on the mount. It felt nice and snug as it was.

I used some synthetic super lube that I got mail order. It is good to -40T but I am not much good below +40F so it should be thin enough for me. Actually, I have no idea how much to use so I did a light coating of all contracting surfaces.
Ah, maybe March will have clear skies and less frost.

Glenn,

Great tutorial on the Tasco mount! I happen to be surrounded by 7te5 parts at the moment, and I was just getting ready to revamp the mount next. This is great timing.

The scope I'm working on now is one I picked up on the Indy Goodwill auction last month. Although not mint like the eBAY 7te5,( I also just got), it is cleaning up very well. I think I inadvertantly paid UPS extra for shipping about 5# of good Indiana silt loam soil... mostly caked on the objective. The glass is clean now and looks fantastic.

I'm really going out to the woodshed right now for a piece of kindling to make a "spanner wrench". Thanks for documenting your trials, errors, and successes here!

Carol,

I have a 76mmX1200mm Mayflower that rides on this same mount and tripod. Exactly the same except it has a larger tube clamp, a larger counterweight, and it is painted gray. You might find yours is exactly (similar) to this one.

I got the spanner wrench idea from I believe "Astro-Boy" who published it in his tutorial on tearing down and tuning up the CG-5 mount. I actually used the same piece of wood and screws I used then. That way I only had to drill 1 hole. As for a "sticky" I intend to post something to this thread whenever it looks like it might otherwise fall to oblivion because there is such a wealth of info here on the Tasco 7's. Thanks for all the great feedback.

Well, this is my first monthly resurection of the Tasco 7TE-5 thread. I am sorry to report that I don't have a star test or even first light report to share but I just had a knee replacement surgery done and nighttime ambling is probably another month away. But the sky has been continuously socked in anyway so even if I could go out it wouldn't do any good. I am wondering what is the relation between the 7TE-5 and the 7TE? I know that the former was made by Royal Astro and the latter by Towa but did their production overlap or did the Towa made scope precede the Astro model? How do they compare optically? If anyone has both I would be interested in a your impressions of how they stack up against each other.

Congratulations, Glenn! You did a fabulous job restoring your 7te-5! I too have some work to do on the equatorial head of my 7te-5. Only problem is that it is missing a few parts. If anyone has any of the following spare parts for the 7te-5, I would be happy to purchase them:

1) 1 - two piece chrome plated Latitude lock bolt unit. (I have the one on the degrees-scaled side of the unit. But, I think they are both the same)

2) Both RA and DEC slow-motion control flex-cable adjustment arms.

3) The thumb screw that secures the counter weight along the DEC shaft.

Currently, I am using an EQ-2 to hold the 7te-5's OTA, but I want to restore the scope to its original appearance. Look forward to replies via this forum, or email (vsc-astronomers@vega-sky-center.com) regarding the parts listed above. Please let me know if further clarification is needed.

Hi Glenn,

Have not compared the images between the 7te and the 7te-5, but my instinct tells me that the 7te-5 would be the winner. But, I must say that I have a feeling the 7te would not be far behind. Since the 7te-5 (1000mm - f/16.7) has a slightly longer focal length and possibly better corrected optics as compared to the 7te (910mm - f/15), I think the 7te-5 would be a sure bet. I also own a Jason 60mm f/15 with a Towa objective. The 7te-5 has better CA correction and can handle a bit more magnification. Not to take away from any of the fore mentioned 910mm scopes, because they are true performers in their own right. But, I love the pinpoint star images, contrast, and CA correction in the 7te-5.

They also make the 7te model in the 910mm focal length. I have never seen a 1000mm 7te myself, but surely (as we all know) in the 7te-5 model.

Perhaps the 7te came in both focal length sizes. Or, the ad neglects the "-5" designation.

Hi Charles,

Yes! Although the were often advertised incorrectly.

the 7TE has:

-910mm focal length
-The focuser is a great one with a long, single tube - can take a 1,25" adapter.
-The earlier version had a collimable lens cell. Later version did not.
-The GEM mount is basically the same as the 7TE-5 but does not have setting circles (earlier versions may have had them)
-finder mount is anchored on the OTA tube.

The 7TE-5 has:
-1000mm focal length
-Collimable lens cell
-The focuser tube has two focus tubes. One draw tube and one rack and pinion focus tube.
Gem mount has setting circles.
Finder mount is anchored on top of the focuser body.

Hello all. Dawson, thanks for your kind words. I have no extra parts since when I put it back together there were none left over. (That's an unusual outcome for me) Preston, your explanation was very clear. Is it true that all the 910mm scopes were made by Towa and the 1000's by RoyalAstro? My impression is that the 7te was made before 1966 and the 7te-5 was from 1966 on.
The weather report has claimed we will have clear skies here in a couple of days coupled with mild (about 30*) temperatures so I hope to get a chance to check out the optics on the Moon, Venus, Orion Nebula, and at least one bright stat then. My hybrid star diagonal from Agena came so I can use some 1.25 eyepieces. I will report if I actually get to use it.
Clear skies all.

You most certainly deserve the kudos, Glenn! You did an awesome job on your restoration. Just wait till you put the hybrid diagonal to use with your 1.25" oculars. You are going to be pleasantly surprised. I have the same diagonal and have used an Orion 5.2mm Lanthanum (192x) on the 7te-5 with it. That's well beyond the norm when it comes to the maximum amount of power to use per inch of aperture. The view was great!

Look forward to reading your results.

Confessions of a weather wimp. There have been 3 or 4 clear skies in the last two weeks but I have only set up twice and both times I have beat a hasty retreat to the warm house after a pitifully short session. I am amazed at how little viewing and set-up skills I have retained after a short hiatus. My first attempted to polar align the mount had the RA axis running N - S but backward so that the RA axis actually ended up perpendicular to the pole. Then I couldn't align the finder with the main scope. By the time I got it pointing right Venus has dropped behind some trees and while I could make out a clear and color free crescent through the bare branches, there were a bunch of distracting spikes of glare. Imagine a 6 armed RR crossing sign squished vertically and there you have it.
By this time the first quarter moon was near the zenith so I started with a 21mm TV Plossl in the hybrid diagonal and was very pleased with the 47 power performance. The field was uniformly crisp and did not show any vignetting from the necked down diagonal. I was getting pretty uncomfortable by then but did try a 6.7mm Meade Plossl before quitting. After later looking at an atlas, I determined that I was observing the Mare Frigoris just north of Plato. There was a small scarp running diagonally in the plain that that showed very sharp and clean at about 149 power. My plans to switch to a higher power eyepiece were canceled by my body's refusal to stay out any longer, especially considering that all the stuff I had got out had to come back inside before I was done. Ah well, when I pulled the dew cap from the scope to replace the lens cover I saw the lens was already frosting over. Sure 'nuff, time to bag it for sure.
About a week later I made another attempt to do a first light report. Again, the evening started at about 30 deqrees but the temperature fell rapidly and I was chilled out before long. I did get some nice 150 power views of Venus in it's fat crescent glory. No glare and no spikes tonight. I did get my wife to come and see the planet. I looked longingly at Orion's belt but again the shivers bested my desire to observe and I hastily packed up again.
What I learned about the scope:
1. There is no false color on bright objects.
2. I haven't found the resolution limit. 149 power (about 62X/Inch) doesn't begin to challenge it.
3. Contrast is excellent. Bright mountain peaks and ink black shadows are cleanly juxtaposed with no glare.
4. The mount is reasonable stable - not rock solid but the shakes damp out in a short time.
5. Gee, I am glad I got it. Think it is a keeper.
Clear Skies and WARM SOON to all.
Glenn

Do you know what thread size that is? I might can get one from my hardware store or I might already have a spare.

Hey Glenn,

First light sounds good (and cold). I haven't been able to motivate myself to go out for long on the few clear nights lately. Clear = cold here too, although not nearly as cold as you get. My daughter lives in Bozeman now and swears that even though the temps are much lower there it feels much colder in Oregon at similar or even higher temps. You know it's not the cold, it's the humidity It will be warmer soon enough. I understand from Montana expatriates now in Oregon that summer is the second week in August there. I suppose you don't even sleep that week

I have two 7te5 scopes I'm looking forward to playing with soon. I was looking at M-42 one night last week with one, and my lens fogged/frosted over as well. Those emission/reflection nebulae are really cold!

Warmer clear skies are coming. other Keith

Hi David E!

Thanks for offering a screw to retain the counter weight on t e declination shaft on my 7te-5's mouont. I do not know what its thread size is, but I was hoping to get an original. No way would I put you out to purchase a replacement alternative when I could mosey on down to my hardware store and snag one. I really appreciate the offer.


Thanks,

Mel

Hey Mel. You can replace the latitude adjustment bolt with the proper metric cap screw and maybe a washer or too. You could even get a machinist to drill and tap some little holes in the faces of the hex head into which you could screw some hardened small hex bolts. Wouldn't it be cool to have a six spoked capstan for locking it down? Actually, the latitude adjustment on this mount is not very well thought out since if you bump the counterwight shaft in the dark you will probably move your latitude adjustment as well. I also have a problem with the legs wanting to colapse on me as well. The mount definitely requires a light touch to stay in adjustment.
I am not sure what you mean by slow motion attachment arm. If you are refering to the metal stub to which the flex cable attaches, I think that that is integral to the worm itself and you need new worms to fix it. If you need just the flex cables those are the same as the common Vixen, Meade, Celestron jobs that are often available in the classified or A-mart. Good luck in getting it together. With respect to using all original equipment, in the dark they don't know unless you tell them.
Clear skies and some HEAT PLEASE!

Hey Starpoke,

Thanks for the great idea to use a hex head bolt as an alternative to the original latitude adjustment bolt. As I mentioned earlier, I guess I was just trying to get the unit back to its original appearance. But, really I am on the same page as you and David.

When I initital received my 7te-5, I was mainly interested in the OTA. For I already knew how great the optics were. But, I discovered a myriad of issues with it. The focuser's pinion rod was bent (which I replaced with one from a total different telescope's focuser) during shipping, along with having missing parts. Nevertheless, the optics are prestine. Currently, I use it atop my Jason 313's EQ, which works fantastic.

I must apologies for referring to the flex cables as "arms". I should have known better. But, it is the flex cables that I actually need. I have checked AstroMart and various other venues and will continue to do so. They all pretty much have the same size mount fittings, so you are correct in that I can used them from other small refractor EQ's. Guess I will have to go the route of fabricating, substituting, and using components from other scopes to get the EQ head operational. Just would have loved to get OEM parts.

Thanks again,

Hey Strdst -Other Keith
Not only do I also have a daughter living in Bozeman, I also have one living out your way - in Newport, Oregon. Montana weather gets a bad rap. Only occasionally is it extreme. Some years summer weather starts in April, and then usually we get some more in May or June. July is generally dry and is often the best viewing of the year as forest fires often smudge late summer and autumn skies.
I was able to get out for a short while tonight and do a quick star test with the Tasco 7TE-5. At 167 x the out of focus star image was nearly identical both inside and outside of focus. The racked in image was a little darker between the central dot and the diffraction ring than in the racked out one and the central dot seemed to have little pinpoints of light inside the dot while in the racked out position is was more of a uniform blur. I don't have a clue what that means but I think I need to get my Optician buddy to come by and do a more controlled test. Preferably when it isn't so cold out.
I also look a look at the Pleiades and M-43. The stars were nice and sharp. There was some haziness contributing to glare but the airy disks were nice and tight. The Orion nebula was something of a disapointment. Perhaps I have been spoiled by the 94 Brandon's glorious explosion of steamers of nebulosity but in the Tasco with the TV 15mm wide field it was very muted. I could only see 3 stars of the trap as well so I wonder if there wasn't some partial cloud cover too.
Well, I am developing a routine for this drill. I set up the mount, scope, table, chair, and eyepiece case before sunset and go in. After dinner I Throw on some extra clothes and get a flashlight and a mug of hot mocha. On clear nights it cools very rapidly and I generally have to pack it in before the beverage can even get cold. Well, perhaps I will get hardier as time goes on.
Clear WARM skies all
Glenn

Hello Everyone! I'm delighted to see continuing discussion in this thread regarding the 7TE-5,and enjoying all the recent posts on this great instrument. As of late I 've been busy with some other projects nearing completion and will soon begin plans to disassemble ,lubricate and reassemble the telescope's equatorial head,including the installation of an electric clock drive unit bought from JMI .Looking forward to using the scope after the work is done.Clear Skies,Gary Barabino Sr

My very similar scope is a Carton, 60mm/1000mm. As I built it from parts, it is not entirely original, but the lens and tube are. The cell and dew shield are Towa, and the focuser is a 1.25" from Meridian (really nice all metal R&P). The finderscope (and bracket) is a nice 6x30mm from Agena Astro.
That is the scope in my avatar, and it's one of my very favorites. Exquisite view.

Yesterday I decided I was in need of a guide scope for my 6"f12 refractor.

I wanted a white tube, white dew shield, black cell, no tube mounted finder, no mounting holes in the tube, just a clean tube to use as a guide scope in a set of rings and to match my 6" in appearance.
I started with CList and found a "Tasco For Sale" looked like what I wanted, that one will do.
Went to look at it and right away I could tell this is not your average 60mm.

Air spaced lens, adjustable cell, helical focuser gears, the focuser threads into the tube, 1000mm fl, what is this?
And the mount, what a piece of work that is. Nice tall legs, what is this thing?

It didn't take me long to find out thanks to CN, and I have decided if it works half as good as it is made I won't be using it as a guide scope.

Hey Robert,

From the information you provided, it all points to possibly being a Tasco 7te-5. Was there a label attached to the focuser? There are a few other "old school" brand names that also had white 60mm x 1000mm FL refractors on the market, such as Monolux, to name one.

Yes it is a Tasco 7TE-5.

Yesterday I finished cleaning everything and star tested it last night. I have a straight thru .965-1.25 adapter so I can use my good diagonal and EP's.

It was no surprise that it had perfect in and out of focus images and I'm glad I didn't need to do any collimation.

I also tried it out in the day time terrestrial and it is a very fine scope. I do need to blacken the inside of the draw tube if I want to do much more of that.

It's a shame that Astro Optical didn't really get the credit for this marvelous instrument. Just a tiny little trade mark stamp that no one ever payed any attention to.

Robert

Awesome, Robert! Happy to know that it is a 7te-5!

A agree with you that Royal Astro Optical did not get the claim to fame it deserved for its part in making this fine instrument what it is today.

Here is a link to an old Royal Astro Optical catalog, which showcases their own line of scopes. You will be happy to see a familiar scope in the group.

Hi Mel,
Can you find out the date of that Royal Astro Catalog? I noticed that the 60mm scopes listed there are 700, 910 or 1200mm focal length while our Tasco 7TE-5. is a 1000mm instrument. I wonder if they sold that scope under their own name as well.

Hey Glenn,

You are correct! The 1000mm is not mentioned in this catalog, which is said to be from around 1970. Sorry I did not thoroughly check out the specs. I found another Royal catalog though that has a 1000mm, but the EQ is different. The OTA does appear to be quite accurate to the 7te-5, except for the camera mount attachment connected to the telescope's upper section. It is on page 8 in the catalog and is from around the same time, or perhaps a bit later. Here is the link.
