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.
