Frames
I took thirty 8 second exposures on a tripod, the light frames.
And fifty shots with the lens cap on, the dark frames for the stacking program to remove noise.
Stacking
Then stacked them in Sequator.
Editing
The stacked image was edited in Darktable.
Result
And finally cropped to roughly 16:9 aspect ratio.
Showing Andromeda on the left third, and trailing off to black on the right.
