vdB 9
van den Bergh 9 is a dusty reflection nebula in Cassiopeia.That bright star in the center made this a very challenging image or process.
This is 37.25 hours of LRGB data and both PixInsight and Photoshop were used to process it.
For all the technical details see astrobin.
The image below is the first processing attempt. I tried to manage the glare from the central star but was a bit too aggressive with the dehaze in photoshop.
