This is an old favorite I decided to look over once again and see if I could improve. I went ahead and filled in the blank corner with the single channel of H-alpha data available. It’s not great quality compared to the rest of the image but it is decidedly better than nothing. I also decided that the purple stars had to go, however much I like purple. Previous version is here.
This nebula glows brightly in H-alpha. There’s not much other than that here. The three filters used were f675w, f656n, and f555w. The wideband filters were useful for making the stars visible.
North is NOT up. It is 131.4° counter-clockwise from up.
Hubble data is public domain, but I put a lot of work into combining it into beautiful color images. The minimal credit line should read: NASA / ESA / J. Schmidt
