M 42 Orion

This object is a nightmare for an astro tracker – the southern sector. However, as soon as I got my old Canon in 2019, even before it was modified, a friend and I went out of town to shoot M 31. It was October. By the end of the session, Orion rose, and I managed to take just 8 frames at 120 seconds each before the tracker batteries died. I came back to process it now and decided to restack it in Siril.
