NGC 2170

An interesting process — the main body is mostly in Ha. 29 Ha frames and three 10-minute RGB files. Interestingly, the hydrogen itself is very weak with this amount of integration and very noisy. I didn't use masks or cut out the stars. I noticed that any sharpening, denoising, and similar operations act somewhat like a mask, shifting pixels from one channel to another — it's interesting to watch how the machine works. This is my second attempt at processing; I decided to approach it with a fresh mind. I'm finishing it in Lightroom, sometimes having to juggle between Siril and Lightroom. Equipment: CHI-1-CCD.
