Description

A field with M81 and M82 taken at my home in Vermont. Skies were not great and captured around 180 minutes of luminance and 30 minutes in each color channel. I used a TEC140 with ASI6200 mono camera and Chroma filters.

The colors are not what I expected, and will take another run at them. I did not expect the orange-ish colors in both of the galaxies. I probably need to take another run at processing.

I left the background a bit brighter than usual to show some of the IFN around M81.
