Work on the errors has been done. The green cast has been removed. Stars and integration have been fixed. A more accurate HDR for the hydrogen nebula and more color =)

In my opinion, the best M20 on this portal.

Not bad at all, the scale is nice — the image looks good.

Scale is good. But if you had framed it a bit higher and to the left, it would have been perfect. Though I wasn't really bothered and just centered on the object's marker without even rotating the camera, since I was shooting everything in a row anyway.

Zhen, could you crop it a bit? That would cut off the whitish streaks on the right and bottom. At least on my monitor, they're clearly visible. Other than that, it's all very good!

Yes, I know. It's more of a necessity than an option =) I noticed this band during processing, but on the desktop monitor it didn't look intrusive, so I decided to leave it as is, without any crop. But after a while, I looked at the work on the MacBook screen and realized I should have cropped it after all.)
