Description

Acquired over 6 nights from home.

Revision B: Added in 5 hours of SII, and changed the processing to simulate H-beta by mixing some Ha into the blue channel.

Revision F: An attempt at a Hubble palette version. I used Straton to remove the stars and then layered RGB stars back in. Ha was used for luminance.

I still think I like the 'natural' color better, though... What do you think?
