Galaxy season approaching so time to try a galaxy. Trying longer exposures of 10 minutes to capture the faint spiral arm detail.

Had to be careful with the curve adjustment. Wanted to bring out the spiral arms detail but not over brighten the core.

Data collected on three nights. 12th November & 3rd & 20th December

LRGB image with 6 hours and 20 minutes of data. 18 x Lum 7 x Red 6 x Green 7 x Blue 10 minutes exposures.
