Photo description / processing

I shot over two nights a little bit at a time. On the first night with 120-second exposures, stacked them, and it seemed the stars were a bit overexposed. On the second night, I set it to 60 seconds. Then I stacked everything together with drizzle x2 and reduced the size a bit. A good little scope, I like it. Shot in HDR mode on the camera, gain 9, offset 100. Imaging sessions on September 12 and 16, 2025.
