New, old refractor!

Well, today I picked up a 1964-1966 Unitron 4" EQ Model 152. The OTA looks like new, the mount looks like new and the objective star test looks great. I got the Unihex, a full set of EPs, the Sun viewer, tripod with folding legs (really nice, stows much shorter) finder, threaded counter weight. Wooden case for the scope and the EPs, but a Pelican case for the mount.
The scope is very original, with only a small mod to the lens cell, set screws were added to keep it collimated, the spring loaded cell tended to lose collimation.
I will try to get a photo of it as soon as possible.

Congrats. I hope it meets or exceeds expectations...

Floyd,

Your fate is sealed. With the purchase of that 152 you have contracted the chronic disease -- refractor fever.

Sounds like a nice rig.....soooooo lets see some pics smile

While we wait here is a pic of one I just found that is on its way here. While its not a Unitron (I wish) it ought to make a nice companion on the 8" f/15 I am building. Vixen spec doublet (same one as Antares Elite, same 2 speed focuser too) 90mm f/16.67. Was built by Joe at Parallax who kept it a couple years before selling it. Supposedly an exceptional lens and a great double splitter.

Ok, a few picks taken when the mount was set up at the sellers house.

This one shows the complete scope with Solar Viewer installed. The Unihex of course is not used for this. The Slow Motion shafts and flexible cable were not installed in these photos, but they are all there.

You can see the folding legs in this shot. You just loosen the big Wing Nut and rotate the Aluminum part 90° and the leg folds between the other two leg supports. Nice walnut legs, very sturdy and large in size compared to the others he had on other Unitron mounts.

I'm late to the party here, I know, but I have some questions:

What is the current market price for a Unitron 4" optical tube in mint condition? (When I was a kid, I really wanted one!) Unitron 5" optical tube?

What is the level of color correction? (I assume they're just good, long-focus achromats.) How do they compare to the D & G's of today?

How consistently good (or bad) are the optics?

Where can I learn more about Unitron refractors?

Thank you.

Bill

Goggle Unitron History Project. Just about all you ever wanted to know about Unitron is on that site. 

To the original poster, congrats on the Unitron 152. I have a 1953-54 Unitron 152. The mounts are amazing considering their age. The Astonomy Shoppe website sells a RA motor with a hand controller that is battery powered and works like a charm.
