Description

Version B has somewhat reduced noise in the background.

A tough object to capture and process due to the dim nature of the nebula and the brightness of nearby stars. I made sure Rigel was outside the field of view but even then, I had to crop out some of the image to cut down on the glare. I was surprised with the amount of background Ha in this image as almost all other images of the area don't show much. Perhaps this image could be improved with the addition of Ha data as the background is quite noisy due to the aggressive stretching needed to bring out the nebulae.

L 24x150s at f/2.8. RGB 10x100s, f/2.0.
