I agree, it does look like it's on a Unitron mount. Goto and Unitron mounts each have their own very distinctive features and it is unlike any Goto mount I have seen, and looks very similar to Unitron mounts (with the exception of the counter-weight which doesn't look quite right, but that could just be the picture; the legs also do not look like Unitron legs). Goto had the provision of selling both full kits and OTA's only. The Goto I know best personally was sold by Goto as an OTA only. My guess is that this one either came originally as an OTA or a previous owner sold the mount (which are in high demand amongst collectors due to their uniqueness and rarity in this country), and then at some later time, the scope was placed on a Unitron mount (which would have been a good paring given the quality of both scope and mount). The counter-weight may be another indication that changes have been made over the telescope's lifetime. Does the Unihex have a Goto or a Unitron logo on it? I am not aware of a Goto Unihex, although some high end Sears telescopes (and I believe Royal Astro? scopes) came with an unbranded Unihex.

And the turret on the scope almost looks like a Super Unihex.
The mount looks like it has the leveling bubbles on it. The legs I agree look Unitron. The counterweight is some ruby goldberg addition. If that came with the scope that was the deal of the century. Maybe it will be known what eyepieces are in that turret and close up picture of the mount and turret??????????????

I have discovered the mystery of why the baffles were removed from my 4" GOTO. After I removed the front cell I discovered that the baffles have been replaced with a flock lined insert.
The man I purchased the scope from received it with the baffles out already and never attempted to install them. He only used the scope twice and was amazed at the lack of chromatic aberration with no baffles in the tube. Now I understand why. I have not told him yet what I discovered. He has no idea why the baffles were removed. I am excited about the prospects for thermal equilibrium and inhibited light scattering offered by the insert. I am eager to get a look at Jupiter with this scope.

Did the scope and the mount come together along with the the turret?

Yes they all came together. I know almost nothing of the ownership history. The turret is indeed Unitron with a combination of Unitron and GOTO eyepieces.
The mount has no manufacturers markings at all. It has a tiny light bulb and toggle switch underneath center pointing down that would illuminate the ground between the legs but I have not yet figured out the power source.
The man I bought it from machined the counterweight out of bronze so it is not original with the mount.

Unitron mounts have no markings or logos. Some have the light you have. I believe you have a Unitron #142 mount.

You probably got the best of both worlds...a Goto refractor on a Unitron mount. Congrats!

You have the 4" Unitron 152 mount. That is the only Unitron mount with a light. What size eyepieces does the turret take? Is one of them a very large 60mm eyepiece?

The light unscrews from the mount and then you will see the battery holder. Pray that the batteries are not still inside. They are D cells and if have been leaking will almost make the light useless. Please take some pictures of the light when you take it out and off the turret. Also, the light would shine on a wood tray that would connect between the tripod that would hold eyepieces.

Wow! I did not realize it to be the 152 mount but duh! Yes, of course it is. There are several Goto threads and posts running consecutively and for some reason I overlooked that your scope is the 4 inch (right there in your post header :foreheadslap: !!!) and assumed it to be the 3 inch. Or perhaps this was subconscious as my only personal experience with a Goto refractor was with a three inch. So with a 3 inch refractor as my mental scale I assumed it to be a 142 mount while all the time, it was staring me right in the face! :foreheadslap:

Wow! You are lucky indeed to have the 4 inch Unitron equatorial mount. :waytogo:

Very lucky. Almost afraid to ask what you paid for that set up?

You are correct. I have confirmed with the man I bought it from that it is a Unitron 152

Bhanks,

The turrent takes 1.25" eyepieces, and yes, one of them is a very large 60mm!

I paid $450.00 for the scope and mount which I think was a very good deal. He originally asked for $500.00 and I countered with $400.00. We met in the middle and shook hands. I picked it up the next day. I had already decided that if he was firm on $500.00 that I was going to take it. :jump:

A very good deal! The mount by itself is probably worth more than twice that.

Yup...I'd estimate you received about $3500 worth of quality stuff for $450.
