NGC7635 The Bubble Nebula
This is a reprocessed version of the narrow band image of the Bubble Nebula, incorporating the star colours from the RGB image. I have been refining my PixInsight techniques using Warren Keller's book "Inside PixInsight" and some of the lessons learned have been used to develop this image.
So this is an H-alpha, SII, OIII, RGB image. There are five hours of H-alpha data, six hours of OIII data, and nine hours of SII data all in 20-minute subs; there is also 30 minutes each of RGB data in five-minute subs. These data were gathered in October and November 2016.
