M31 - My First Real Deep Sky Image

Many years ago I attempted some deep sky astrophotography with a DSLR and lens but didn't put in the time for necessary integration nor the time to learn proper processing techniques so I gave up trying after some disappointing results.

Jump forward about 10 years and I began accumulating some relatively inexpensive gear to make data acquisition a more streamlined process and watched hours and hours of youtube videos about processing deep sky images. This image is the result, my first "real" attempt at deep sky astrophotography.

72 X 2 min. exposures from my Bortle 5/6 yard
Nikon Z6 (Ha modified)
Canon 400mm 5.6L @ f/5.6
SkyWatcher AZ-GTi
Guiding, dithering, & acquisition using ASIAIR Pro
Light and flat frames stacked in Sequator and processed in Photoshop CC - no dark or bias frames.

It's certainly not a perfect image (for starters, it's a little "warmer" than I'd like so I'll make that adjustment) but I'm happy with it as a start. Much of the processing inspiration for this image came from Peter Zelinka's youtube video where he processes an image of Andromeda in 10 minutes.

Thanks for looking!
