Oeswww

Not bad. I'm curious how mine will turn out.

Thank you. I think it's much better.

5 minutes of sub-exposure at such high gain - isn't that too much?
I wonder what the sky background looks like in that case.

This is the working gain at 585. I started shooting back in February during the dark nights. But either the weather was bad or the moon was out, so I couldn't capture more hours. Regarding the background: with 15-minute exposures, the dust didn't increase further. It had already blended into the background. I shot for 40 minutes and then abandoned it. It wasn't suitable for stacking.

It would be interesting to see a single BIAS frame, a DARK frame (if you took one), and a single sub-exposure. Could you send them to sikd@mail.ru?

I don't do calibration on this camera.
I'll send it soon.
