Wow, cool! I didn't think it could be seen properly with a 135mm lens!

Hello! This is a crop, of course. But still, it was taken at 135mm.

Of course, it's a crop sensor, but still! I just tried M3 with my 37mm lens—it came out really tiny. I've never seen the Ring Nebula with my own eyes, but I read it's very small. I thought it would be about the size of a star...
Btw, how do you process the background? I get that you use FitStacker, but what's next? I have the same lens, the same camera, and roughly the same level of light pollution. I even use longer exposures at the same ISO, but my background is just very noisy...

I always have issues with the background, my friend. I'm amazed at how people manage to get such smooth results without gradients even with very long exposures. I process in Fitswork just like everyone else—selection, gamma adjustments, and so on. Sometimes it just turns out like this mess...

And then in Photoshop, do you do anything with the background?

I hardly know Photoshop, so I just make slight adjustments in Correction levels/curves, etc.
