Celestron c11 sct, Skywatcher NEQ6 pro mount,Atik 383L+ camera, motorised filter wheel and Astronomik LRGB filters.

Famous dark dusk cloud against a deep red emission nebula.

Also managed capture some of the blue reflection nebula NGC 2023.

Challenging to image with the bright star Alnitak causing reflection problems with my 8″ scope.

My 11″ scope has a smaller field of view so had no reflection issues.

HaRGB image with 4 hours 52 minutes of data. 20 x 7.5min Ha, 17 x 2.5min Red, 21 x 2.5min green & 19 x 2.5min blue.
