Description

I could try to brighten this or increase the saturation, but I think I'm going to leave it as is. I like the moodiness. I tried for many nights to generate tone maps but the O-III and S-II data weren't turning out very well, so I finally focused on controlling star sizes instead. This is a Hubble-ish palette, but the O-III and S-II are boosted substantially. Can you see the black hole (Cygnus X-1)?

Description: Reprocessing from scratch. My calibration frames had problems in the original (double-subtracted bias?). Also did a better job of star removal for the tone maps and tried using PixInsight's NoiseGeneration process to smooth the transition between areas of nebula and erased stars, before stretching and combining the narrowband channels.
