This month, very active poster to our forum,Garyth64 has provided this image of his favorite classic to start the June thread. Gary had this to say when I asked him about the scope.

msg-125173-0-99723800-1651376545.jpg

 

"I had a hard time deciding which of my telescopes to highlight here.  Although I have had many classical scopes, I have always loved the homemade ones.  I decided on my 8" f/3-f/18 Gregorian.

Why a Gregorian?  I felt that with its concave mirrors, it was something I could make.  After having many discussions with some members of the Detroit Astronomical Society, and mainly Tom Waineo, we settled on a f/3 primary.  I began grinding the 8" mirror during the summer of 1968.

 

I had trouble getting a good curve on the f/3 primary, and Tom Waineo took the mirror back to Boston with him, where it would touch it up.  Tom also generated a 2-1/2" secondary with a RoC of 11.5".  I polished the finished the secondary using a null test.

 

By 1970, the scope was done and the optics were mounted in a sonotube.  The back plate was made from 3/4" plywood.  Very crude, but it all worked, and gave some pretty good views.

 

Because of life events, the scope was dismantled and the optics were kept in a box for about 30 years.  In 2012, I remounted the optics into a aluminum tube, and made new cells for the secondary and the primary.

 

The primary mirror suffered a few chips on its edges over the years.  They weren't very large, but could easily be seen with looking into the scope.  So last December I decided to make a new primary for it.  I ground and polished another full thickness mirror and kept its f.l. within 1/2" of the original.  I've made other mirrors and they came out very good, but this f/3 curve for me started to take up too much of my time.

 

I asked Mike Lockwood if he would finish the mirror, and he said yes.  Thanks Mike.

 

So this picture shows my Gregorian in 2012 on one of my homemade mounts:"

 

Great looking build Gary.Thanks much for sharing this with us!

 

The basic guideline for this thread is to list ads and auctions for classic/vintage scopes and associated accessories that others may be interested in. Do not post your own ads or the ads of your friends, this includes items you may be trying to sell for someone else. We request that you do not post photos from ads. If you must have some reference to a photo in the post, post a link to the photo, not the photo itself. Concentrate on the item for sale, and not the seller.

Please post a live link to the item. Do not post "PM me for the link".Short discussions can take place about the items listed. When quoting a post, edit the quoted post to include only the part you are replying to. Do not post the entire ad text, or large blocks of it, without permission from the author. Keep on topic, please!

    Buyer Beware- CN is not responsible for any of the ads or auctions posted here or their content. There are some scams floating around, so do your homework before pursuing any ad.

                                                              and this note from the moderators
Let's remember everybody, there's no one place that has all the best-used scope finds just as there's no one place that never has anything. All have something. No need to beat subjective matter, whatever the topic, into the ground. For the sake of all of us who love the classic forum, please keep moving the thread forward. Remember that many of your fellow forum members are already vintage themselves. Instead of restating your opinions over and over, consider sharing something new, insightful, or otherwise constructive to the topic at hand.

That last one.  If the guy only knew what he had.

Seems like the best deals spring from:

-Relative died, estate up for sale.

-Friend gave it to clueless friend.

-Decluttering by someone who just doesn't give a hoot how it goes as long as it does.

From those photos no one knows what he has. In my opinion it's always better for an experienced astronomer to possibly get a deal than a stranger to be given a heads up he has underpriced a scope they don't know much about.

When i have fire sales i sell cheap. But the buyer has to come pick it all up in one shot. Gonna sell off stuff this weekend for 10 cents on the dollar. I am cleaning house for good and only keeping 2 scopes.

I have always loved that aluminum scope you built Gary   

 I believe for some years it was featured in your avatar which is where I believe we all have seen it

  Very nice

Asahi Pentax 85/1000 (OTA and box only) - $200 in Cedar Park, TX

 

https://www.facebook...547414606778045

 

This listing posted by jragsdale in the locked thread is a superb buy. The telescope is rare and offers nearly APO performance in a perfectly sweet sized aperture and focal ratio. Too bad it does not have the mount but the scope by itself is still very special. Here is my video about one quite memorable telescope!

An oddly good-looking C8 Tricolor, SN 623. Comes with a wedge, eyepiece, cord. Reasonable price IMO

https://www.ebay.com...00AAOSwojdil6pK

If I didn't already have a 7" Mak and Dobson's 8" I'd buy this. I am puzzled as to how the paint is in such good shape or if it'll last.

Good luck with your sale. So which two are you keeping? Hopefully that mint Vixen 4” on the GP is a keeper!

The Unitron was on Offer Up as non working decorative scope for $20. I contacted him to get it but he now wants $125.

He added photos changed the description, deleted it and relisted so it's possible someone has told him what it needs etc..

It has a very large clam on the objective but is probably still worth it to a flipper for parts.

That said, I don't need it enough to bother or have the time to drive and play games.

That's the best-condition original tricolor I've ever seen. must not have been used much.  And no, it won't last.  In a year or two, it'll look (and feel) like an overcoating of snot had been generously applied.

His FB listing was published 5 hours ago at $15, maybe he just wants it gone now?

I'd get that Uni 114 in a heartbeat if it was anywhere close to Denver Metro. 

I don't need it, not even for parts. I'm curious if the mount is the same as the one used on the 50mm Uni model 105. 

There is little info on the model 105 and I'd like the chance to do an actual mechanical side by side with a 114.

The Brandon 94 is a superior scope made by Roland Christen (later to found Astrophysics). It is a triplet APO. Though early in the universe of APO telescopes, it delivers great images. It is heavy, though. This one comes with the original counterbalanced mount. This is not the mount found on Unitron 114 telescopes and is sufficient for the scope. It also appears to have an original finder. I believe this was only offered as an additional option. All of those features make this a fairly reasonable deal in my estimation. It's a little high though, so you might be able to negotiate and get closer to $2000 which would be a great price.

 

Here is my video about such a scope. Although my scope was labeled 92mm it was actually a 94mm exactly like this one.

Yeah, that's what I figured would be the case especially here in AZ where it's quite hot.

The Vixen C102 is beyond insane sharp, so is the Meade 826. So they stay till death as well as a ST80. Just not worth shipping a ST80 so it will be used on clear fall nites with a 16mm Nagler. I don't plan to buy anything unless local and has to be something that is crazy priced or something rare i have not owned.

Soooooo, the original paint on the early tri colors melts with exposure?  The paint on Serial Number One was well worn but still solid compared to decomposed.

No it wasn't.  I saw it at one of the PATS conventions.  It looked pretty bad in person.  It was also only the OTA serial No 1, not the whole scope.  The rest of it consisted of a hodgepodge of mount parts from the mid to late 70s.

The 94mm units (as opposed to the 92mm) were lighter.  The mount is undergunned for it though.

He states it doesn't work and the front lens is cracked. He's probably gotten conflicting information from the busybody squad and now regrets even posting it.
