Description

And finally here is another version of my previously posted Ha-NIR image of M42 and friends. I'm just learning a completely new (for me) imaging technique and I'm trying new ways of image processing.
In this version I tried to emphasize the hidden or barely visible stars with a spectrum peak beyond the VIS spectrum. It's really interesting that there are several stars appearing in NIR!

Pixel math:
R = MAX(Ha, NIR)
G = Ha
B = Ha

Enjoy it!
