Compared to the previous version, I worked on reducing noise in the shadows, as well as improving contrast and saturation.

How huge it is! How long did it take to collect the signal? What causes the dark halos around the bright stars? Or are they actually like that?

Dark halos from shaky hands :(. As for the signal, my apologies, I missed it in the description, I've added it. Didn't actually gather data for that long.

Sometimes, I also get those dark halos around bright stars. Can you tell me what causes them? As for 2.5 hours of integration time—for me, at least, that’s quite decent! I’ve never spent more than an hour or so on a single target yet—either clouds roll in, the Moon rises, or the batteries die in the cold :)
