Andromeda galaxy (M31). Decided to try out the 6D on Andromeda at the end of the night, only 10 x 1 minute at ISO 3200, no darks, iOptron ZEQ25GT equatorial mount + Canon 6D with a 400mm f/5.6 lens. This was using a single star alignment.
Now I’m curious what 60+ minutes will give me with dark, etc.
Incredible shot, Tom! Thank you for sharing!
