It seems to be in mint condition. Does anyone know anything about their performance or reputation?

Vintage Sears Tower or Discoverer Telescopes
Do you have any more details on the age and/or construction of your scope?

There was another one I lost the bid by only a dollar or so
Here is the link to that one:
Would appreciate your comments on both. They look beautifully made. Unlike today's telescopes.

The scope you bought looks like a smaller version of mine with a simpler mount. Probably around the same vintage. It will probably include some bad eyepieces. Mine had a useable 22mm Kellner. The rest were not good. For $36, it's a decent gamble. The other one looks a bit newer. If it seems in good shape when you get it, you could try to find a hybrid diagonal that will let you use some better 1-1/4" eyepieces. In any case, let us know when it arrives.

I now have both the Tasco 9TE-5 and the Sears. Yesterday I tested both with very high power eyepieces (1.25" o.d. barrels with a hybrid adapter, no diagonal). As good as the 9TE-5 Tasco is the Sears seemed to have less chromatic aberration. They are both 700mm in f.l.
Later at night I looked at the moon, Saturn and Jupiter. On Jupiter I used a 7mm Televue Nagler and Meade model #140 2X Barlow. Chromatic aberration was not very noticeable even a 83X per inch! It was difficult keeping the object in view with the alt-az mount so focus could have been better and perhaps the image crisper but that might be expecting too much from a simple achromat.
The views of M42 and the moon at ~28X with a 24mm Televue Panoptic were incredible. The earthshine on the moon stunning. Otherworldly!

Yes I am quite crazy about telescopes. No children, no wife, no bad habits. Will be rich and retired by the end of this year or next...so what is there to do except pursue my hobby?
