I recently came upon a Tasco 49TR from about 1980 which was in new condition and apparently had never been taken out and put together. This is obviously a low-end alt-az scope, but I figured since it was Made in Japan and most things were metal it might be worthwhile. The mark on it is Diamond-Z, whatever that means. I don't collect telescopes; this is the only one of these old scopes I have and I only gave $20 for it.
This telescope has to be the biggest piece of trash ever made. It looked nice in its box, I'll give it that. Even the color pictures on the box were conservative and made it seem better than it might be. But the mount is so sloppy and poorly designed that you really have to question what they were thinking. And, the still-sealed plastic baggies were missing the wing nuts. The set-screw .965 eyepiece ring would not stay in the focuser drawtube, even though the threads look fine. It's simply not made with close enough tolerance to really thread in right. The focuser has two very rough spots in it, even though the rack/gear look fine. The scope is so nose-heavy that even wrenching down on the two Alt thumb knobs won't hold it up for long! And, the already tiny finder is stopped down so that the aperture is only around 3/8"!
You don't even want to know about the eyepieces that came with it!
I did some work and got the scope usable. The most interesting thing I've seen are the out-of-focus images of bright stars. I have never seen such a beautiful bulls-eye. I think the only way I'd want anywhere near a 60mm these days is if it were very short focal length, though. After using big reflectors for years, the scope seems very dim, and most stars are not there. Views of Saturn were as good as they could be, though. Very sharp! I never sold my .965 eyepieces so I have many, from Kellners to Orthos to Plossls.
One thing I had forgotten was the way of using these scopes on such poor and flexible mounts. You kind of point the scope, then eyeball through the thing and wiggle until you see what you are looking for flash by in the eyepiece. Then, you know what direction the target is in so you push a little harder to try and get the scope to move there - but not too much. It all feels very "elastic."
