Deep Sky

Andromeda Galaxy

Last night were great viewing conditions, clear skies, almost new moon (which rose fairly late), good seeing (low atmospheric turbulence) and not too hot or too cold... Had a bit of issues to get the setup to work properly again (since I had taken it apart for my Montana travel), but ended up getting about one hour of integration time. Very happy with the outcome though. This is the Andromeda Galaxy. A bit over 2.5 million light years away. 6 Light frames (10 minutes each), 50 BIAS frames, 10 Dark frames, 20 Flat frames and 20 dark flat frames. Nikon D750, Nikon 500 PF, SkyWatcher AZ-gte, ZWO ASI120 Mini Guide Camera with 50mm Guide Scope, Custom Autofocuser
