Ok, so I'm about to become the owner of a criterion dynascope 8 inch deluxe in rough shape......I have posted it in the ebay/craigslist finds thread here....can't help myself, as I am more excited about this scope than just about any others I've acquired....im probably crazy even since I've posted so much about it and have yet to pick it up!.......anyway, I would love to hear from anyone who has one, had one, restored one, or any information I can get!......it looks to be complete, but everything will need to be restored......while I have lots of telescopes, this is my first newt.....I want to do it right, any and all advice is welcomed.....

while I'm confident I can do the resto of mount justice, I will need lots of help for the optics.....assuming the mirror is not junk, who can help with evaluating the optics, re coating etc?.........I want to do this right!.......

 

lots of rambling here....but figured I would go ahead and start the restoration thread now!

Bob, as I told you privately, I'm so happy for you!  I was happy to bow out for someone passionate about it.  It's a great scope.  As I said, I have many fond memories using one just like it.

 

i strongly suspect everything on this scope is going to simply tired, but otherwise excellent.  You may need to recoat the optics, but nothing wrong with that.  Can't wait to see it!

Don't worry about it - we're here to help :)

 

Before considering sending the mirror off for a refigure, it would be best to test out the optics first.  Chances are it may just need a recoating or nothing at all.  Depends, it'll need an inspection and star test.  Familiarize yourself with how to collimate a Newtonian.  There's good info over in the Reflector Forum. 

 

The scope will need a careful touch when you start taking it apart.  Best advice I have is to document everything and take lots of pictures (and post them in your thread!).  There have only been a couple of threads about the Criterion Dynascope 8" Newtonian here and hopefully the folks that have them will speak up with help from their experience.

Thanks George!.....you are a great example of folks working together here on this site!

I want to publicly thank you for your kindness and respect when I said I was serious about pursuing this telescope....George simply acknowledged it and said he would bow out and help me get the scope anyway he could......it just doesn't get any better than that.......

Remember seeing theses scopes back in the 60's in SKY & TELESCOPE and getting a  information about the scopes.  .  The company also made the RV-6.  Looks to be F/7 or F/8.

 Bob, Nice find! I've had a couple of these and currently have an unrestored OTA in the garage. Don't know if you're aware but if you remove the mount from the bell housing base,there should be three short legs attached, some were wood others aluminum. That's one of the scopes that I've enjoyed using the most. I remember dialing in Messier objects with the excellent setting circles it has.

A thread about my 6" model. I had many nice nights this summer with this scope...

Nice color coordination, right?

I had the 6 and 8 back around 1980 and both had super optics.

Oddly enough, when I joined the company in 1979, there were barely any traces of the Dynascope line in the shop. I think they left it all behind when they moved from the Church street location.

I did buy the last remaining 12-1/2" mirror and secondary that we had in inventory, though. Which I have since sold.

I'll be virtually no help to you but for in spirit.

Ask the seller if you can have his permission to repost the pics from the ad.  I've done that several times in the past.

I think the biggest challenge to restoration won't be the optics, but the wrinkle gray finish on the tube, if it needs repainting and not just a good cleaning.  You'd have to find a paint shop that could match the color and mix the paint for you, since I've never found any source for wrinkle gray anywhere (Optical Craftsmen piers were wrinkle gray).

So, if the scope works and looks decent after you've cleaned it and recoated the optics (if they need it), I wouldn't take it apart.  Just use it as is.

Very classy scope you are getting Bob.  :bow:  :bow:  I had one like it for a couple years. Fortunately my ota was in excellent shape. The mount and pier needed lots of work. My thread is here.  http://www.cloudynig...scope-8-deluxe/

Glad you got it.  I would have bought it when I found it if my scope fund was not "tapped out" at the moment..  Looking forward to the restoration pictues.

Thanks all......whewwwwww,......what a day!.....I picked up the scope......it is very tired....and will definitely need a complete restoration......but, it is all there, and under the grime and peeling paint, in very good shape......It is missing it's wood legs though.......no big deal as I'm better at wood working than metal!......

mirror is intact, but with fungus/coating issues......no prob, I anticipated this......all in all, it met my expectations, which was"awesome"  :waytogo: ......I'll get some pics and post ASAP......

oh, btw, for the tube paint......could one spray with wrinkle finish black first and then add the correct color?

Oh, one last observation.......mine only has 3 counterweights versus the 4 I've seen in most pics......not sure if one disappeared or if original......seems to balance well though.......good night!
