M42 bicolor (Ha, OIII, OIII)

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

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

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.

Beautiful, very much so!

Did you forget to remove the green noise? The SCNR process in Pixinsight.

Not only with good materials, but also by improving the quality of other objects, adjusting exposures one by one, and mastering the tools and software—this is the pure essence of astrophotography for me and fellow enthusiasts. M42 is impressive, Andrey—we look forward to your new successes.

The green tint was never removed.
