I recently accepted a "project telescope" from one of the astronomy clubs I belong to, on the condition that I work to refurbish and restore it.  I'm starting this thread to document that effort as it progresses, in parallel with requesting your help along the way.

 

Do you recognize this scope?  One clue - I'm intentionally using the term "antique", vice "classic", here. (Dave and Robert are disqualified, due to "prior knowledge"  ;-) )

Well, at least most of the paint has been stripped off already!

From what I see, I’m guessing it’s a 4” Tinsley!

That's an alt/az saddle that goes on a horse shoe style stirrup. Kind of like my 1928 B&L.

Sunkist - you got it...a 6" Tinsley Saturn f/16 refractor on a rising pier tripod...probably dating to the late '30s/early '40s.

Wow! That almost looks like a trick photo where you would be posed far behind the actual eyepiece. That is a beast. Can you use it as is?

Amazing! I have never seen a Tinsley Refractor larger than the 4”, just heard the fables. Nice to know that they really do exist! Fan-Frikking-Tastic!!!

I'm certain John will be along to provide additional details...and more photos...but that thing is a real monster...and this is coming from someone who has dealt with 5" and 6" Unitrons!!

Love the massive size.........so impressive.  Makes you look short like me John....How does one transport something this big? Does it actually fit in a basic SUV?  How is its size relative to the big Spacek you showed us at Neaf in April?

 

Good luck on the restore   we all look forward to pics as the long term project proceeds

I can use it with the Unitron drawtube Dave provided me...and with a temporary repair to one of the OTA baffles...but those need permanent repairs, and the objective a thorough cleaning, for it to be fully "back to battery".

The tube (with focuser) is 83" long...the legs are almost 6" long. When I picked it up, I used our minivan with the middle and back row of seats retracted. John

Does anyone in the club know where it came from?

It has early features like my 4 inch, the finder rings are like X in my drawing, and the objective uncoated? I

confirmed my lens is uncoated by examining the fragments.

so - a short summary of condition:

It is mechanically complete, with the exception of the focuser drawtube and the threaded adapter that attaches it to the end of the focuser

The 6" objective is dirty (dust film and some discrete small particles), and may have small areas of fungus...but otherwise intact. The objective cell is in good shape and comes with its screw-on cover (cover has no "Saturn" tag on it). The finder objective (42mm) is less dirty, but could still use a cleaning.

The OTA tube (which is 1/16"-thick aluminum) has some dents that need to be removed before painting (none look like they would impinge on the light cone from the objective). The rising pier is operational (has a operating crank at the bottom of the pier assembly).

Now to the paint - the OTA looks like it was painted a dark green (looked under the tube rings). Over 50% of the OTA is bare aluminum. The tube cradle, finder OTA, fork, tripod head, and rising pier assembly are painted a dingy black, but again, large areas of those assemblies are bare

The tripod legs still have much of their original stain, but need to be refinished. each leg has a small caster attached...these may not be original.

So, that's where it stands...looking forward to talking with you on this!

One additional feature: the rising pier is a 30" brass column inside the black casing. It's operated by a handwheel at the bottom of the casing, which very smoothly raises the interior brass column (at the rate of several turns per inch of elevation).

Initial look at the objective would indicate that it is uncoated.

Geez, I saw the title of this thread and I wondered which of us you were referring to.  ;)

 

Really sweet scope BTW.
