Was planning to use my 80mm refracter but I’ve misplaced my field flatner. So back to my 12″ telescope.

Tried a closeup of NGC206 star cluster on the edge of M31 to begin with. It was too faint with poor results.

So switched to the brighter galaxy core. Much better.

I always have a couple of backup objects in mind before each imaging session just incase.

Used a photoshop layer mask to stop the core being to too bright in the final image.

Increased exposure time to 15 minutes to capture as much faint detail as possible.

Data collected on three nights. 2nd & 3rd & 5th October.

LRGB image with 11 hours and 0 minutes of data. 20 x Lum 8 x Red 8 x Green 8 x Blue 15 minutes exposures.
