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.
