Description

I’m currently beta testing the new Astronomy Technologies (Astro-Tech) AT12INT 12” F4 Truss Tube Newtonian Astrograph courtesy of www.astronomics.com and here are my First Light images from January 4th 2016, seeing conditions were 3 out of 5 under my Bortle 4 skies.

I’m very happy with the results so far and enjoying the scope, would be much more fun if only the weather would cooperate. I’ll be doing a review of the scope once I have completed testing.
