Description

Here's my take on the Iris nebula (NGC7023). I shot this on 3 separate nights from dark skies and home. I had a little trouble processing this because of some weird issue with star alignment between L and RGB that I finally managed to resolve.

Shot at gain 0 because of the huge dynamic range of the target. I wanted to get as much of the surrounding dust as I possibly could without blowing out too much of the nebula itself.

I had some trouble with keeping the focus stable (until I realized the Esprit 100 focusser has a little lever at the bottom for heavier equipment). I lost most of my green channel to that but managed to salvage a few frames which were enough for the final image.
