Brand new 9" F-18 refractor Pics
      #514124 - 07/13/05 03:15 AM Attachment (2162 downloads)

These are photos of the latest completed 9" F-18 refractor. I can not express in words how absolutely beautiful this scope is up close. These pictures don't come close to expressing it. It was completed three days ago by John Pons. When he rolled it out of the garage, I wanted to cry. Don't be fooled even though it looks like the 10" F-16 Zeiss, it's not even the same scope as you will soon see. The gorgous 2 element objective, which is going to be housed inside will all be owned by a respected Alvin Clark collector. The air spaced objective was designed by James G. Baker. For those of you not familier with this man, he is considered by Thomas Back of TMB optical to probably be the greatest optical scientist of the 20th century. I have tested a lot of BIG refractors including BIG apos and the star test on this scope is nothing short of sensational. Literally picture perfect star patterns on both sides of focus with no signs of astigmatism or spherical abberation. You could not buy a finer two element objective in this size. Before the objective was sold, we tested in Pon's 12" optical refractor tube which normally houses the 10" Zeiss. This allowed us to test the 9" F-18 objective on numerous occasions. So sad, that people do not get the opportunity to see such beautiful craftsmanship and tack sharp planetary images at these wonderful focal ratios. I will add more pics for all of my friends to enjoy. I was so bummed that Pons was letting it go and when I saw how little $$$ it went for, I really wanted to cry.

These are the knife edge baffles which John Pons designed himself. The baffles do not not intrude into the light cone, but stay just slightly outside of it. read Advanced Telescope Making. Pons is a grand master at designing his own refractors and owns a gold mind of scopes people could only can dream about. The blue prits will be up soon. When we set up these refractors during planet season, it's like being there. truly, some of the most beautiful work you'll ever see. Notice that the baffles will be slid into the tube and tightened in.

Here's a pic of some serious scopes. The larger scope is the 10" F-16 located in my profile. The smaller scope is the 9" F-18. My friend Wayne is in the back ground wearing the green shirt. Pons is in the far back ground. Notice that the 10" is slightly off white. The 6" F-15 GOTO is in the background, while the pier in the far back holds a whopping 18" Buyers gear to hold the 10" Zeiss.

More close ups. Notice the Unitron label. The focuser was taken from a historical classic. One day I actually walked into Pons house and before my eyes was an actual 4", 5" and 6" Unitron all on their orignal piers and in original condition. I nearly had a heart attack.

This illistrates how long these things actually are. Easy to see why the images are sharp.

For the Coronado, they call it the BF30. I think this would be a BF40, haha. I put the cell phone next to it for relative size just for fun.

Hello Daniel, WoW...Thanks for posting these wonderful pictures of these large refractors...it gives me new hope!!!

I just aquired an 11" f15 doublet refractor that Roger Ceragioli refigured to a .995 and was So overwhelmed by it's size, was looking for a local club with a dome to which to donate.

But seeing these wonderful instruments in his front yard, gives me new hope.

Best Regards,

Preston

Now why did you have to go and show me those scopes?

Now I have a 'Laura' complex... Lusting after the unattainable. I'm even jealous of just the blueprints.

By the way; where do you do take the beauties to observe and how do you transport them? If it's anywhere public I hope I can see them

Thanks for sharing these images Daniel ...
Some questions:
1. What are the finderscopes on these giant refractors ?
2. What is the weight of the 10 inch ?
3. Do these guys also make custom Dew Shields for smaller refractors ( e.g. 150 mm aperture ) ?

I gues the cars have to stay out of the garage there and these refractors are ch... crowd magnets on Star Parties

You know what, friends?

While these scopes are gorgeous, harkening back to the years when the long focal length doublet reigned supreme, I'm glad they are not in my charge! I applaud Daniel and his friends for carrying on the tradition and thank him for sharing the wonderful pictures.

These are MAN scopes to transport and mount, as the biceps in one image attest. Not only are they monsters, but you had better have your finder accurately aligned. By my calculation the 9" f/18 can muster little more than 1/3° of field with a 24Pan! But who cares for Mars this fall.... Where does the line start?

The finders are Zeiss.
Weight of 10" is about 200 lbs. One ton with mount.
No on the dew shields.

Thanks for all the kind words folks.

Well I guess these might become available?
Or are these on-request custom-made ?

Anyway, words fail to describe these Refraktors ... These are the real Planet Killers

Wow! These scopes are astounding! With people like Pons out there I think there needs to be a show on cable television that captures these brilliant telescope makers doing their craft. Kind of like "American Chopper" or "Rides", but with telescope gurus dishing out their philosophies on how to make magic with objectives or mirrors. Amazing.

I am also . What would be the cost to have one of those big boys made ? Not to mention the mount it would require . Being an F-18 would their still be any CA ?

Are you kidding me? Pons is a grand master with Newtonians. I learn from listening to him. There's nothing I could teach him about Newtonians, because I learned it all from him. If you think these refractors are nice, wait until you see his fully completed and upgraded 12.5" F-6 super planetary Newtonian. The mount you you saw in the photo that had the wheels on it is for the new Newt. The planets at 12.5" at F-6 using fans and a thin curved spider would make all of us cry. I nearly drowned to death in my own tears. Planets look totally aesthetic at 300, 400 and 500x. Like perfect Voyager pictures. When you see Saturn for example in any of these scopes, including the giant refractors, the rings literally reveal tiny grooves and divisions. It's just an entirely different level of observing and it's hard to describe in words sometimes. We now have a friend with a Takahashi 300 Mewlon who will be observing with us, so we should have a pretty interesting array of good performers during the next Mars run. Pons is a 53 year planetary veteran. All these guys do is crush one another if they can, it's exciting to see it in action. My 12.5" F-5 Starmaster is completed, but I wont know how it stands up for sure until we do the tests during Mars.

As far as the color correction at F-18 in a 9", it's suprisingly not bad at all. At that ratio, it really helps. It doesn't matter anyway, I just got word that the scope is now staying with us and Pons has an extra color corrector for it anyway if we want to take it up another notch. When seeing allows, the images at these long focal ratios are TACK sharp and I mean TACK!

You've got to be kidding.

That has got to be the greatest collection of scopes I have ever seen. In my life....

I can really appreciate my custom made 6"f/15 on its hydraulic pier.

Man, and I thought I had it good.

It says something of the care the man takes when the OTA stands look so well made. He is obviously a perfectionist in all things.

Well, thank you.

I just finished building the 6"f/6.5 imaging scope, and am working on the custom filter wheel.
Using it as the counterbalance was a stroke of....well, it works just fine, sine I have no tripod legs to get in the way.

Placing the EP at eye level when viewing objects at zenith is one really great benefit.

Thanks for your comments.

Funny thing, but I have few pictures of me, and the scope for perspective issues, but this one was taken just after I aquired the scope after it sat in storage for nearly 28 years.
This is before any restoration had begun.
As you can see the pier is partially elivated to get a better zenial view.

Here's a picture of my AstroPhysics 6" f/12 apo Superplanetary refractor.I'm kind of toying with the idea of selling the OTA because I just don't get out with it very much!!I didn't even bring it out once for the 2005 Mars close approach...though Mars 2003 was most awesome!!The poor baby sits in the case most of the time.The set up time and breakdown time are around a half hour.I sure would like a scope that would take a lot less time to set up and allow me more time to image the moon and planets!!Any ideas on what I should do??My heart says keep it,my brain is confused!!After seeing those gorgeous 9" refractors,it makes me want to hang onto my 6" f/12 "dreamscope" even more!!!

I understand your confusion. Here, I'll help by taking that AP OTA off your hands (heck, I'll even give you, say, $150.00, which can go towards a larger APO or whatever). Trust me: this is the only way to telescopic salvation .

Hi Robert, Keep it!!! Make a decision in haste, regret it at your leisure. I have two Unitrons, a 2.4" which is quick and easy to set up and a 4" which takes as long as yours. I sometime wish it would take less time to setup. But when my eye lines up to the eyepiece I remember why I've kept it.Cheers, John

I can't speek for the others, but, I know.
Really, that's a wonderful scope, you have.

Set up time can be used as *cool down time*.
The offer stands. My scopes would luv a new friend.

John,

Because I am one of the many, *you know your...* guys, I almost enjoy setting up as much as viewing. Set up time is like foreplay. Or something like that.

It never takes over 15 minutes to set up *Little Big Man*.
What takes the longest, is waiting for Polaris to become visible to do a polar alignment.

Robert,
Just a thought, you could probably trade for a tec140 and be pleased with the results, only .5" smaller and better DSO views, and quicker set up time, and still "portable". And you would use more often?

I came to the conclusion a long time ago, that bowing before the celestials would be an act of the heart, not of the physical knee, or the back.... Prostrate is just humiliating

Come out one dark clear night, and experience stable, firm Zenal viewing on your feet.

Which are the largest aperture Refractors widely available?
I have a 6inch but are 8inch refractors common ?

From what I gather, 6" instruments are becoming the more popular size, due to mobility, and light gathering ability.

D&G make some very nice large aperture refractors, and TMB probably makes the largest APO's in 6"-12" sizes.

Due to the light pollution issue most are dealing with, 6" appears to be the workable limit. Plus, if you have an endless bank account, 6" is about the finacial limit for most.

But lets not forget the mount that is required to run such a scope. they can be more expensive then the scope themselves.

6"-12"=$8000-$40,000 Aprox.
And mounts to put them on are,
Ap900-Paramount/Parallax=$6000-$40,000 Aprox.

So from that, it isn't hard to see how really *common* these rigs are.
You see very fiew at star parties.

Rob,

I'm putting in an offer on a friend's 8" f/12 D&G later this summer. My guess is he'll part with the OTA for $2500. Then the only challenge becomes getting it from PA to OR. 'Course then there is building a pier mount, finding room for the mount, finding room for the scope, figuring out how to make babbit bearings, finding room for the wife and kids (outside!)...other than that...no problem! I guess I could always go for the 'hand-held' option.

With the tripod it is mounted on now (which I won't get), and looking anywhere but horizon or zenith the darn objective still hovers around 12 feet off of the ground.

I can't wait! ('Course if my friend changes his mind in the end, I might be trying hard to get Robert to change his mind on his Superplanetary )

Keith,

Sounds like you have a plan. Just remember, it might be *you* who is going to live outside, after all your exploits.

Hey,, wait one minute...That means your new scope will have a focal length 6" longer than mine.

You will need a mount at least as big as mine. I hope you have been saving your Rubles.

You can always rest it on a fence...

I have to say, though, I hope you do indeed get it, and find a place for to store it, and find a nice place to mount it, and.....and..... I sure hope your family can stand the strain.

Rob(gettin an 8" scope, what's next......)

Both my six's equals 12, and that means I still win...


p.s. I hope you know, I am joking...

P.S. If you find your OTA's rolling around on the lawn one morning, I will claim complete ignorance on the whereabouts of their mount.

P.P.S. I think that's 15" in the picture, not 12"...

Pons is a grand master at designing his own refractors and owns a gold mind of scopes people could only can dream about. The blue prits will be up soon. When we set up these refractors during planet season, it's like being there. truly, some of the most beautiful work you'll ever see. Notice that the baffles will be slid into the tube and tightened in.

Well, I welcome your attempt to try to aquire it without screaming and yelling after you blow out your back trying to just remove it from the pier.

We used to use a chain hoist from the garage rafters to put it on the pier head plate.

My son and I put it on the last time with brute physical force. I will not attempt to repeat the vulgarity that escaped out lips as the attempt was made. I never knew a single piece of steel could weigh that much.

If left outside for late evening viewing, it is itselfs own anchor, and can't just be put in the back of a fleeing car.

Still, consider yourself invited to come and try.
And when you fail, we can sit back, enjoy a nice cup of blended coffee, and view, till we meet the morning.

Rob,

My parents are sending an older B&W picture and I should get it in a few days. I will post it then. The 8" lens was ground by Barry Greiner before there was a D&G. I grew up looking through it, and now that our friend is older (80+) he only takes his 6" f8 out anymore and is considering selling the bigger scope. I'd like it for sentimental reasons, plus the fact that I know it is a good instrument.

Just kidding about the mount...I'm a powerlifter and I know how quick the iron adds up. I might have to pick your brain for technical data however. I'm considering using 4" rigid piping with babbit bearings to make a hand-driven equatorial, but I'm not too sure about how to keep the hydraulics of modest proportions.

Well, first. It aint just Centimental, but *Historical*.

You get that action, and hang on to it. I'll be prayin, you do indeed get to aquire it.

As far as *pickin* my brains, you had better do that quick, for I fear I am loosing much as the days progress towards the future. I can't even find my key's any more.

Nope, won't work. I've used that excuse on just about every purchase lately. That one's just about worn out with the 'missus' and I've gotta think of something else...quick.

The other famous excuse..."this will be the last one" has been history for quite some time, so that won't work either.

Ah well, still 1 1/2 months to go until I get back to PA. I'll think of something.

I hope.

Dude, we gots to be smarter then the girls on this one.
Let's see.
OK, You need to explain that aquiring this scope will enable you. And will fill that whole that will complete who you are.

You need to make it abundently clear, that this instrument contributed to the building of your steller character. And with the knowledge of it going to another, you would expressively reduce the memory of your childhood to insignificance.

You my friend, would in essence, be irepairably psychologically altered. And subsiquently your future as well.

Rob,

Your humor is infectious.

Thanks for the ideas. (The wife was reading over my shoulder, though, so they're out as well. I shoulda looked first. If it helps, she laughed too.)

YOUR WIFE WAS READING OVER YOUR SHOULDER?

Now there is a soul that plans on never getting to be the one in the promised land saying, "neaner, neaner, neaner".

My friend, if you ever hope to aquire such a fine instrement by stealthful means, you need to learn the art of convincing your sweetheart that your *needs* are her needs. A complete commited form of communication, and listening skills can materialize instantly after such a fine instrument is resting comfortably within the walls of your garage. Then and only then, can all the dreams of marrital bliss she envisioned (before she met you) be fulfilled.

So, my friend, the way I see it, she has no real choice (if she wants marrital bliss),but to fulfill her destiny, and agree to her enchanted future.

Then again, I could be full of the makings of a raving lunatic; your wife isn't remotely buying into any of this,(cause she already had kids), or you don't want what's behind curtain #2, and you want to keep the bag of mercy your wife so generously dispences daily.

Looks like our scope gear won't be growing any time soon.

Rob(somebody shoot me)

Nope, won't work. I've used that excuse on just about every purchase lately. That one's just about worn out with the 'missus' and I've gotta think of something else...quick.

The other famous excuse..."this will be the last one" has been history for quite some time, so that won't work either.

Ah well, still 1 1/2 months to go until I get back to PA. I'll think of something.

I hope.

Keith,

Best of luck if you do get it. I've been tempted by the 8" class of achromats several times, but unless I could get two really good large flats to make a dual-fold set up it wouldn't be manageble for me at all.

Gentlemen,

Here's a pic of the 8" f12 (pre D&G) D&G refractor. Since this is a scan of a B&W copy of a B&W photo, and since alot of contrast was lost before I got it, I had to enhance the upper portion of the tube assembly with a pencil line so it could be seen. Other than that, it is unretouched.

I'm quite excited about getting it, but you know what the say about chickens....

Daniel,

It is about 25 years old, give or take a few years. I think my parents photocopied the original on an office scanner before sending it to me. The crease down the middle where it was folded to fit the envelope.

I will (hopefully) soon be joining the ranks of the big guns. (Rob, I think the wife's will is beginning to crack but massive bribery is definitely in order!)

First, I want to say, congrats, and I hope you can finalize the deal. It IS final right?

Second, I want to encourage your wife's fantastic supportive attitude. You do realize that with her support, you will be on the end of the stick that will now need to reciprocate her expression of luv, and encouragement of your hobby. I don't really know what that means, but I bet she will be more then happy to remind you of it.
Often...

In an expression, in honor of this hollowed moment, please allow us to worship, the one, who is the fulfiller of dreams, the one who who finds no sacrifice to large (when it comes to you), the very one,.. yeah, who is the..... controling stock holder in your blessed institution....yes your sweetheart.

Rob(behind every successful man, there is a wife rolling her eyes)

Hi Valery,
the only objects where I can see colour errors with higher magnificion are Venus and Sirius.
And this is okay for a semi-apo-design at F15.
Last autumn I got high quality pictures of Mars at 330x with no haze of colour errors,
using a 60°Baader-Bino, Baaader Glaswegkorrektor 1,7x and a set of two Zeiss O-10 eyepieces.
I do not want to change this scope for ever.
It,s razor sharp !
August Sonnefeld was a great optical designer
with kindly regards from germany

Gentlemen,

Well, I'm afraid there is going to be no deal on the 8" f12. Essentially, my friend wants $2500 for the scope, minus the focuser too now, and he is pretty firm on the price. Considering an 8" f12 with an AP 2.7 focuser just sold in Maryland for $1975 the other day, and a new one directly from D&G is $3400, I think I'm going to pass on this one. Options now are keeping my eyes open for a used (and complete) 8" f12 around $2k, or buy a new or used 6" f/15, which might actually be the more sensible choice. But...since 'sense' usually doesn't figure in any of my purchases...

Daniel,

I was just told that the Pons 10" f/16 Zeiss has been tri-spaced with a lens manufactured by Roland ... If true, that must be an impressive performer indeed! I was also asked to pass on to you that when you see John again, tell him Rodger (in PA) says "Hi, and great work on the 9 inch ".

How much does that puppy weigh? Do you think a CGE mount would handle it? I have a 6 inch Skywatcher, and the CGE handles it. But your 6 inch looks larger. Wondering what the weight difference would be.

Dietmar,
Thank you. This 9" objective was actually designed by James G Baker, probably the greatest optical scientist of the 20th century in Thomas Backs own words. The star tests look identical on both sides of focus. We also have a color corrector for it as well. The thing that I find most striking about these long scopes is how tack sharp they are. Very pleasing indeed.

I have to say, I am very sorry it all fell through.

In my view, it lets you know that there is something better out there for you.

One thing wonderful came from all this...

Does Pons actually use them, or does he just build them???

Plus, does he sell them???

Does he have a shop on hand to do all his handywork in, or does he ferry out the work???

Did he make the black EQ head, and pier???

Do you know his plans for these scopes???

Good Lord, with the questions

Pons designes everything and has all the blue prints to these scopes. All the drawings are his. We are currently working on two 6" F-15 D&G refractors according to his specs. He doesn't really sell scopes for a living. He's been around this for 53 years. In our group he's the grand daddy of it all but the guys are all incredible observers to say the least. We are all very fortunate to have wonderful locations and scopes to view with on the west coast. I don't know if the Zeiss will ever be sold. It's value is estimated at a quarter of a million doallars. I saw one of the finest views of Saturn with it about the size of a fifty cent piece.

A local astronomy chapter club in Vancouver used to have in a dome a superb 6" Zeiss refractor so the oldtimers say. They sold for it for a song so the story goes stateside many years ago under a great storm of controversy. Everytime I hear the story about the sale of that scope it's time to hit the blood pressure meds big time . Just the thought of what the views must have been like in that scope and it's loss to the local astro community sure put me off joining the this club to say the least.

Add on:

A plaque still exist to this day on the side of the dome commemorating the installation of the Carl Zeiss {Jena} 6" refractor . Nothing but a memory now unfortunately.

You can claim all you want regarding CA. To have a color free achromat of that aperture you need a lot more than f/18. I love the look of the scopes in a weird sort of way, but they just seem ridiculously impractical instruments. That's my humble opinion.

Actually you're correct. You would need an F-18 but even that's not enough. That's why there's a 3rd color correcting element at the back end of the OTA inside. It was fgured by Roland Christen of Astro Physics. In my refractor vs. reflector review, you can see a picture of the housing which holds it.

Sort of like the Chromacor idea then? It's just that the OTA's are so unbelieveably enormous for their aperture. By modern standards, I call it "impractical". I'm sure they'd be fun, but the mounting would be enough to make a person faint...

Perception is everything in this hobby.
*SEEM* is a very personal observation, and impracticality is still another. IMV Living in a light polluted area is impractical for good stellar viewing, and so forth. But folks still do it.

People don't collect vintage cars, or boats, because they are practicle. If CA is the only wavering issue in the light of superior resolution, and magnification a scope of this magnitude delivers, then I believe that is a short sighted view. IMV, they are awesome scopes that deliver unmatched views compared to the scopes produced for the current common market.

Again IMV a large Dob is just as impracticle, for its gainly sensativities , and the need of a tall ladder places it at the head of the line of impracticle scopes for the average aperture freek.

IMV, a scope of any design becomes impracticle for the owner when it is no longer used.

Rob(I am a fan of all scope designs, I just prefer my 6"f/15 to all the others) It was designed to be *Practicle*.

Hi Stan.
Your story reminded me of a close call our local astronomy group had...
Back in the '80s, a generous benefactor loaned the group a fully equipped 5" f/15 Brashear refractor. All-brass tube, mount, pedestal, drive, accessories, the works.
Some club members spent many, many months refurbishing the antique instrument, until it worked and looked great.
Initially, it got quite a lot of use, but as time went on, interest waned and various people came and went. A few years ago, the club (with a whole new crop of folks in charge) decided they needed a cash injection, so considered selling some of the old equipment that had been relegated to storage. Yup, the 5" Brashear was suggested as expendable!
When the decision was made, there weren't any "old timers" around to set anyone straight... but, fortunately, word leaked out via the grapevine, about what was being planned!
Not only would this have been a really DUMB thing to do, but the scope actually didn't belong to the club, so they had no right to sell it!
Calls were made, e-mails fired off and saner heads prevailed.
Phew!!!...

I did notice the word *Loan* in your post. What were these people thinking?

You know, I almost loaned my scope to a local observatory, I even called the University of Washington. They already have a nice old brass 6".

Now I keep my preserved scope out of harms way, and away from those who need to learn how to appreciate history.

Pons sets up the 10" Zeiss during planet season every year and yes, I view through it whenever it's set up. I have to get up at about 3am to view because Pons only likes to observe when the ground and air has really settled down. At dawn we then put in the Daystar h-alpha which is a .4 ang 155mm setup. The views are all very nice.

What a sight that must be...

The night wanes, dawn is only hours away. The suburban street remains quiet, though, still too early for most to rise and begin their daily tasks. Suddenly, the sound of machinery engaging. From one of the peaceful homes, a sliver of light bursts from under the garage door which begins to widen as the opener engages. The door slowly grinds it way upwards in its tracks. Suddenly, the light is split by two dark shadows, as first feet, then legs, then a torso is revealed. Finally, the face...the smiling happy face of the person standing inside. But what is this? The door has stopped now, fully open, to reveal the monster, the beast, the wonderful 10" refractor, held like a giant babe in the muscular grasp of John's arms as he slowly walks outside and lovingly places it in its cradle.

The silent stars overhead bear mute witness to it all...

OH, goodness.

*As the shadowy figure struggles to cradle the bohemouth; grins turn to sweated frowns as poorly acclimated eyes require greater illumination to adequately install the monolith to life... and precious time is eluded as dawn approaches. As the early morning collection of street refuse is underway, it soberly dawns on the now exhausted seasoned astronomer that maybe setting up last evening around *Wheel of Fortune* time, might have been a good idea*

i just found this thread and i can't believe my eyes! WOW! pons looks like he is in awesome shape, probably from all these years of working with these behemoths. how does one transport these things?
last week i visited astro physics and saw real quality and now understand why someone spends time and money on instruments of this caliber.

Daniel,

how do Mercury, Venus, Uranus and the Gallilean moons look in these telescopes? Hearing your descriptions of Jupiter and Saturn I'm probably the only one eager to know
Clear skies!

Hi Jure,
Sorry taking so long to get back. I have not used these scopes on Venus, Uranus and Mercury, but I have spent some time with it on Jupiter and Saturn. The images are really etched in hard outlines. Saturn exibits grooves in it's B ring which requires aperture and good seeing to identify. Basically it just becomes easier to detect more low contrast features with the added aperture of 9" over a typical 5" pr 6" apochromat. There is also an optional third color correcting element at the rear just like the 10" Zeiss. The 9" on it's own only exibits a little amount of color but still, the actual surface contrast on planetry globes would make any purists jaw drop. Pons own three refractors. A 10" F-16, 9" F-18 and an 8" F-20 and all of them are as perfect as an optic could be figured.

Hi Rob,

yes, I saw this very impressive picture n the big refractor vs reflector
thread from Daniel Mousey. The owner profits a lot from having a big refractor.
As you can see his muscles are well built up

Blue skies and a superb scope, what more could one desire?!

Jon reminds me of Jack LaLane..
Buffin it to the refractor press...

This scope has got to be the best example of a home brew refractor I have ever seen.. And I think mine is a superior scope.

Well I beat Pon's in that I have a hydraulic pier, and a hands free internal electric helical focuser......

Rob(Hey, I'm grabbin for anything I can.. ) It's tough out there.

Indeed, refractor heaven. Pon's aint getting any younger, so I wonder what his plans are for these big guys????

Anyone know?

I will be down in California this spring, and I can pick it up and bring it home if that is all right...

Since there will be little room in your garage if you do get it, you'll have to give me your 6" to free up some space.

I see you're quick on your feet....
However, I would let the car live outside, and take the whole of the garage.

Since I built the garage especially with large scopes in mind(10 ft door, and 12 foor ceiling), I will have plenty of room for it, along with Kerry's 16" LB, and any other scope, I will store.

Now I just need to convince Jon Pon's to let me have it.....

Jon Pons, "greatest optical scientist of the 20th century"??!! You have to be kidding. How about: Charles Townes (co-Inventor of the laser and Nobel Prize winner), Bernhard Schmidt (inventor of the Schmidt camera), or Dmitri Dmitrievich Maksutov (inventor of the Maksutov Camera), etc. I could rattle off the names of about a dozen such luminaries.

(I do agree it's a sweet scope though)

From what I gather he didn't make the lens's or the mounts, and had extensive help on the OTA's.... I could be wrong...

There's obviously been a misunderstanding. That statement was based in reference to James G. Baker, not John Pons and Pons would not say such a thing. Pons knew Baker well and Baker designed the optic in this 9" refractor and for what its worth, Pons is a genious and a 53 year veteran and designed just everything but the actual optics of this scope. Pons designed all his own lens cells. All of us consult Pons for advice, myself included. Were it not for him, the "refractor vs. reflector" forum would not have been born.

Hey Daniel, Did Jon simply design, or did he actually build/machine the elements of the scope?
Did he build the lens cell, and did he build the focusers, and most of all, isn't that a Beyers mount the 9"-10" are seen sitting on?

The reason I ask, is because I have been getting mail from some folks who appear to believe that these scopes are merely the product of others, while Jon, himself simply did designing, but not much else.

I am a bit confused. See, when I hear that someone built thier scope, I assume they actually built their scope. Because my scope was built entirely by my father, with help from me, so I know what goes into actually making a scope from design, to fabrication, to use.....Can you set me straight on this?

I've been to Jon's house and seen some of his scopes and they are beautifully designed and machined. Jon doesn't take a piece of aluminum sheet and roll it into a dew shield, he has it machined from a piece of solid aluminum tube or bar, I'm not sure which, but the result is incredible. Look at the pictures Daniel posted at the beginning of this thread, showing the focuser mount, you have to see it in person to appreciate it. Jon is a perfectionist, and it shows in his scopes. As a machinist myself I can say that whoever made Jons telescope parts is an excellent machinist, but they are ultimately parts made to Jon's design and standards. I believe some parts were CNC machined, and some were manually produced. Like Daniel said, it's sad that more of us here won't see Jon's scopes. He's the kind of guy that loves to share his equipment with anyone.

Let me ask this, how much hands on construction does Thomas Back have on all the telescope that have his name on them? Are they TMB telescopes? Does Thomas get the credit?

I wouldn't be concerned about how many pieces Jon personally machined. When I piece a telescope together from parts I consider it a telescope that I built. No, I didn't make the D&G lens, No, I didn't manufacture the aluminum tube, No, I didn't make the AP focuser, Yes, my daughter machined the backplate.

Yes, I built the telescope.

I think machining a dew shield from solid stock is the most wasteful way to do the job. But if money aint an issue,then do what you want.
On the other hand it is probably very impressive.

So from what you know, Jon didn't make the scopes himself?

I dont care if Pons collided hydrogen until he had enough aluminum to roll his own tubes, or if he got lucky and found the *exact ready to use tube down the street. These are some of the most beautiful scopes I've ever seen.

If you all look at page 1 you will see a drawing w/ Jon Pons' name on it where he designed the baffles of the tube. That at least implies part of the mechanical design of the telescope.

Hi Rob,
When I needed a dew shield for my MN86, I bought an Astrozap. I personally would not say that Jon's method of producing a dew shield or any other component is wasteful. They are his creations made his way, and they are works of art. Few people can produce every component on anything they build. The machinery required to make the parts on Jon's scope are beyond what the above average home machine shop will be equipped with. Nobody but Jon Pon's is responsible for the design, manufacture, and assembly of those telescopes. I've seen the drawings he made for various components for his scopes. The same drawings that the machinist followed when he made the parts for Jon. I've seen a few homemade scopes, and nothing compares in craftsmanship to Jon's scopes.

Hi Rob,
When I needed a dew shield for my MN86, I bought an Astrozap. I personally would not say that Jon's method of producing a dew shield or any other component is wasteful. They are his creations made his way, and they are works of art. Few people can produce every component on anything they build. The machinery required to make the parts on Jon's scope are beyond what the above average home machine shop will be equipped with. Nobody but Jon Pon's is responsible for the design, manufacture, and assembly of those telescopes. I've seen the drawings he made for various components for his scopes. The same drawings that the machinist followed when he made the parts for Jon. I've seen a few homemade scopes, and nothing compares in craftsmanship to Jon's scopes. Did Jon make these scopes himself? Absolutely.
Robert




Thanks for the forward answer.
I respect the method Jon used.

I was just askin.

Rob

I've been to Jon's house and seen some of his scopes and they are beautifully designed and machined. Jon doesn't take a piece of aluminum sheet and roll it into a dew shield, he has it machined from a piece of solid aluminum tube or bar, I'm not sure which, but the result is incredible. Look at the pictures Daniel posted at the beginning of this thread, showing the focuser mount, you have to see it in person to appreciate it. Jon is a perfectionist, and it shows in his scopes. As a machinist myself I can say that whoever made Jons telescope parts is an excellent machinist, but they are ultimately parts made to Jon's design and standards. I believe some parts were CNC machined, and some were manually produced. Like Daniel said, it's sad that more of us here won't see Jon's scopes. He's the kind of guy that loves to share his equipment with anyone.
Robert




Thank you Robert. Your words are correct and greatly appreciated and thank you to all the others who have expressed interest in this thread. What Pons will do is design the tubes and mounts to his specs and has his own personal machinest build the parts, but Pons demands nothing short of sensational quality. If anyone were able to see these scopes up close, the work is simply beyond words. With regard to the 18" Byers gear on the mount for the 10" Zeiss, that is correct, Pons did not make that. There is a set of very small gears that were actually taken from a battle ship on another part of the mount that Pons incorporated into the design.

Pons has helped me to design a 6" F-15 optical tube assembly out of wood, but I'm the one that's building it, but without his guidence, I would have had a very difficult time doing it. I was blown away when the first drafts were drawn by him in one day. He puts so much heart into it. With regard to all these refractors, I've actually seen all the drafts. Roll after roll were countless drafts of rings, tubes, mounts, gears, focusers, you name it. He even designs his own secondary Newtonian mounts. No one has ever seen anything like it. Sadly, I can not display them for public view as he prefers to keep those particular parts private, but they are the finest secondary mount I've ever seen.

He also designs his own solar wedges and there's never been a finer design from any company to date. Unfortunatley that is another part I can not display as he does not want them copied. He also designs all the elesctronics in these scopes and has the drafts he made for those as well. He's a specialist with electronics. There's just so much, it's hard to explain everything. I should also say that with regard to the quality of the optics in all the instruments, the star tests punch out the same beautiful diffraction patterns both in and out of focus and the images are tack sharp in good seeing. Most observers don't understand how difficult it is for refractors of this aperture to do that. Pons is a man of history. He has sketches of planets in Sky&Telescope dating way back. Many people have praised my dedication and sent me countless letters of thanks for many astronomical matters, but it's you guys that have inspired me to share more.

Thanks for bumping this thread, I probably would not have surfed back far enough to see it. Those big refractors are works of history, and art. Need I add, "aperture envy" I once moved a completed roof "1500 lbs" onto the top of shed walls without a crane, it didn't cost a quarter mil. I can only imagine what it takes to move those around.

You know, they call the refractor model I own a "yard cannon", but these in this thread are the ones that are! I am super amazed at the workmanship, and just in awe of the sheer size. To use one, much less own one, would be nearly heaven. I hope as I post this that you and Pons are well and still enjoying them. By the way, they are the first refractors I have liked that weren't black!

Hi, Daniel
You had show fantastic pictures
can you show something planets sketching of the both great refractors ?
Why do to sale this 9 "f18 Brandt-Refractor`? my heart is
Bob Yen has too a 10 inch f16 Zeiss-refractor,he had sale at John Pons?
my Refractor at 2001 and mount at 2006 are homemade ready.
Refractor: D&G 5inch f 2,4 mtr.(f19)in hardpaper tube;Focuser Zeiss ~1950 travel 210 mm 300 €
Objectiv ordered in Jan. 2001, arrived in Sept.2001
the Mount is my design construct the mechanic friend had it work.
my dream is a 10 inch f 20 D&G Objective, now a planned a great mount with 85 mm RA-Axis

Hi,Phil
i think, in USA D&G the best company for Double- Achromat lens-you can not make wrong with this.
you search a 7"Apo ?1 i believe ,you very happening with 8-10"f25 folded refractor is not difficult ~ in money, but very much fun
i had a 7"Astrophysics Apo in 1997, 9 month later i was without work , 1/2" year later i must sale
but today i am very happening with my D&G
for the much money in Apo you must have perfect clima
in German Zeiss is dead for amateurastronomers
for short time i had can taked 8inch AS for 3000 DM (=1500 €)in 1993 but other user came before -i am very on me
for FH you have more Aperture than Apo by money

observatoy building you need always,great mount too for both
ATM it do fun and smaller problem with money
i have made all in homemade outer the Objectiv in five years
for 10-11" Project i need 10 years?
Regards Marc

Indeed "breaking" a large ( huge ) refractor Optical Tube Assembly (OTA) in two pieces is a great idea as long as the connection bit is a tight & correct fit:

Beautiful scopes all !!! And the only one I know who makes custom refractor lenses in America is D&G Optical in Pennsylvania. Ask for Barry.
