Description

Finally could take the scope to a dark place, where light pollution is low enough for LRGB

I've been wanting to do this reflection nebula for a while. The result is surprisingly pink-ish but I'll keep tweaking it...

Info:

The Iris Nebula (also known as NGC 7023 and Caldwell 4), which shines at magnitude +6.8, is illuminated by the magnitude +7.4 star SAO 19158. It is located near the Mira-type variable star T Cephei, and near the bright magnitude +3.23 variable star Beta Cephei (Alphirk). It lies 1,300 light-years away and is six light-years across.
