Classic Telescopes

Telescopes from an era gone by. The place to discuss older telescopes. Antiques, flea market finds, and scopes from grandpa's attic. From the 1780's to the mid-1990's - refractors, reflectors, and early SCT's. Discussing all aspects of restoring, collecting, and observing with older scopes. Discussion of 25-year-old scopes still in production is OK but please don't post newer examples of those, except for actual side-by-side comparisons to demonstrate detail changes.

Equipment (No astrophotography)

A forum for discussion of visual and general astronomy equipment and accessories; a default location if you your topic does not fit into any of the more specialized equipment forums such as Mounts, Eyepieces, Refractors, etc.

Topics related to astronomy cameras and related imaging equipment should be posted in whichever imaging forum is most appropriate to that topic. These can be found in the Astrophotography and Sketching category.
