In this version I equalized the exposure of RGB channels and used some techniques from processing M31, so the colour and details are better. However, the signal-noise ratio is low due to short total exposure. With PixInsight LE, I am afraid that is the most I can get out of the raw data. I really should get my luminance filter when I go back to China. It is very important for capturing details, and cannot be replaced by red filter (at least not when photographing galaxies).
