NGC7000 (North America, Pelican Nebula)

Data from Q3 2019.  Another combo shot I like with Ha as luminance, recombine with masking on normal RGB to get stars back.

Very nice!

If I may make a suggestion, however....

Using pure Ha as the luminance results in blue and yellow halos around the stars in the nebula, because the stars are so much smaller in the Ha than in the color channels.  There are a variety of ways to remedy this (depending on what software you're using); all involve weaving narrow-band data into the broad-band data, so that your star sizes match better.

Great edit Jeff!
