Photo description / processing

Just below and to the right of the Hamburger is asteroid Reigber (6314). There are also three fainter asteroids around the Hamburger. I've processed it like this for now; the L-channel and Ha haven't been added yet. I'm still learning to process mono and getting to grips with Siril.

Ha, I was also planning to place the Triplet there at the same scale. But the weather didn't let me shoot. Although I already have an image of the Triplet, and that "band" (I forgot what it's called) still doesn't show up much.

By the way, the Sharpstar CC 0.95x corrector is bad. It can produce harsh "rings" across the entire frame.

Yes, I have a 0.85x reducer; with it the stars look better, but the scale is too small, so I ordered a 1x SW. There's also a strong glare from the Touptek G filter; they acknowledged the defect and sent me a replacement.
