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.

Electronically Assisted Astronomy (No Post-Processing)

Electronically Assisted Astronomy (EAA) is the use of a camera in lieu of an eyepiece at the telescope to capture and view images in near real time. For the purposes of this forum, near real time images must have a maximum total integration of no more than 60 minutes and cannot be post-processed. The purpose of the EAA Forum is to give members a place to share their observing experiences, talk about the equipment used, and post images captured with EAA devices.
