Description

8 panel mosaic from Barnard's Loop to Orion Nebula for a total of 49.7 hours of HaRGB.

Software used to capture image:
Sequence Generator Pro
PHD2

Software used to edit:
PixInsight
Photoshop

First 5 panels are made up of 7.5 hours of HaRGB
Ha: (20) 15 minutes
R: (10) 5 minutes
G: (10) 5 minutes
B: (10) 5 minutes

The remainder are a little less because I was running out of time each night to shoot it... but with them being brighter areas, they are actually cleaner images. I also shot a little over an hour of shorter exposures of HaRGB for the core of M42.
