NGC 2174 Monkey Head

Ha/OIII/SII, the signal is very weak, it needs to be increased at least threefold.

Alexey, please try to provide as much information as possible about your works. Without it, it's difficult to evaluate them.

The problem is that the hard drive is filled with photos from 1 to 10 years ago, and I simply can't remember the details of them, only roughly. And what criteria could there be for evaluation? For me, it's just like or dislike, while filters, the optical system, and so on are already deeply secondary.
