Description

Second attempt at imaging the Andromeda Galaxy with my newly acquired Skywatcher 72ED and Star Adventurer mount. Imaging from my heavily light polluted back garden (Bortle 8 skies). Finding the limits of this set up -- 30 seconds seems to be max sub length so far.

Any comments or advice always welcome.

I'm especially interested to know other people's experience with the Star Adventurer mount and/or 72ED.

Description: Using what is essentially a masking procedure I was able to selectively brighten M31 while leaving the background a smoother and more pleasing black. In addition, by applying a local contrast increase to the centre of the galaxy only I was able to bring out the centre detail without the grain caused by a local contrast increase across the entire image.
