Description

- the Iris Nebula (NGC7023) and accompanying dark and bright nebulae
- new data from Deep Sky West (DSW) Observatory
- LRGB composite with 37 luminance, 16 red, 17 green, and 15 blue subs with 900 sec each

- used real plus synthetic-RGB luminance for processing, i.e. more than 21 hours of photons
- kept a little bit of noise on purpose, not perfectly happy with noise reduction so far

- again, amazing data from DSW !

- rev B: inspired by Paddy's processing of the DSW data (http://astrob.in/212309/0/), I put more emphasis on the structure and colors of the Iris Nebula itself and kept the dark nebulosity in the background. Moreover, I repeated all luminance processing with drizzled data at twice the resolution, which helped to keep stars tight and structures sharp.
