This was my biggest telescope mistake, so far. An eBay purchase, a momentary lapse of sanity. When it arrived it didn't even have an complete objective, just the crown glass. The tripod was an old wooden photographic one somehow converted for the telescope. I did end up fitting a Zeiss Jena Telementor lens to the OTA and 3D printed a .965" eyepiece holder on a new brass focusing tube. The old girl became a highly usable telescope and is currently residing in a family with two smart young daughters who are on their way to becoming astronomers.
Mistake? I have a feeling that's the type of mistake, a lot of us wouldn't mind making.
