К хорошему материалу, а тем более к М42 хочется обращаться снова и снова. Это новый вариант с новыми освоенными инструментами PixInsight.

Andrey, could you tell me whose filters were used here?

Ha - Baader 7nm, OIII - DeepSky, I don't remember the width, I can't check because it's inside the filter wheel, and I don't want to take it out since I haven't shot flats yet.

Andrey, the M42 shot is good, very good—it's a shame it's in such light pollution, an "Orange Zone."

Thank you for the feedback. That's precisely why I shot it with narrowband filters—because of the light pollution.

Andrey, what we captured with narrowband filters is one thing. Now, if we had gradient filters—with a small circle in the middle of the filter transitioning in different shades, not used for full-frame—that would make astrophotography easier and save time. There are gradient filters, but they consist of two color parts, with either a smooth transition or a sharp boundary between the colors.
