finally went and picked this up.
this thing is so cool looking.
needs some minor work and a few knobs but both drives work
and that joystick is neat also.
here are a few pictures.
ignore that unitron in the background your better off
with a 60mm f/11. :roflmao:

When the scope gets approval from the better half you have a winner.

what Unitron in the background. Please, let's see a picture of that also. I hope it is one of those folded refractors. They are great.

Brian,

I just checked 5 sets of legs (15 legs) and none have those levelers. I've nevr seen them before. My guess is that they are home spun. I have one set that has one leveler screw for fine alt adjusment, most sets have nothing, and one set has a full array of large swivel casters. That caster set is from an 8" that came directly from Joseph Cocozza's work, through his family, to me. These seem to get modified with custom levelers and casters. The end castings are well set up for that.

Look inside the OTA and see if there are only two holes for the bolts that hold that OAG focuser on. If there are only those bolt holes, and none other for a different focuser, then you have a rare factory original indeed. And I hate using the word 'rare'. I think it's overly abused.
Edit: Ahh yes, you have the earlier version OAG. I'm not sure how that one was mounted. The newer ones only had two bolts.

I've always thought those were the coolest looking scopes.
Very expensive in their day.
Can't wait for your report on the spider Brian. Probably not much in the way of diffraction spikes as thin as those vanes are.
How does the foucuser work? does it rotate or split the light cone?

You got a great deal on this scope. The condition is admirable. I think these are unique looking scopes that really sepperate from the standard mold. One thing about them is the foot print. They have a HUGE spread over floor space.

Check the 8 pads (4 on each ring) that directly contact the OTA to hold it in the cradle. These might be bare cork. Felt, in good condition, on each pad can let the tube rotate by backing off the tension screws. The screws push on a metal bar that has pads attached. Check the lower fixed pads to make sure they hold the OTA off the metal cradle. These are built up with cork 'blocks' and rest down into a groove on the cradle end rig. Its easy to grind the OTA into the rings at this location if you rotate the tube.

Nice find. Glad you got it.
