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.

Major & Minor Planetary Imaging

This forum is intended for discussion related to the imaging and processing of anything in the solar system other than our Sun, Moon, and comets. Solar imaging discussion should occur in the target-oriented "Solar Observing & Imaging" forum. Posts about imaging our Moon should go in the target-oriented "Lunar Observing & Imaging" forum. Posts about imaging comets should go in the target-oriented "Comet Observing and Imaging" forum.

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.
