Thanks guys. This image was strictly narrowband mapped to Hubble. I use an FSQ
106 with an FLI 16000M. The mount is a Paramount MyT.
Jim I picked Ha for green because that’s what’s used for traditional Hubble
colors. In the post processing you pretty much get rid of most of the green and
convert it to a gold color. Before I processed the image it was mostly green.

30 hours - that takes dedication...! This is a very nice image. Keep them
coming...
Are you shooting through Red, Green, Blue, OIII, SII and clear filters?
What's the scope, mount and camera?
Question; what was the rationale behind selecting the current colors for the
Hubble Color palette? I can understand Blue or Blue/Green for OIII and Red
for Sulfur II. But why Green for Ha? I know the spectral lines of Ha and
SII are red and deep red.

This is 30 hours of narrowband on the North American and Pelican mapped to
Hubble colors.
