Description

M81 from the backyard stretched just enough to show a hint of the surrounding IFN. I could stretch it further, but with the poor skies here it kind of muddies up the image further and detracts from the main event (m81). Seeing in the low 3s FWHM for most of it. Ha added at 32% of the red channel. Had a little bit of a flat issue on the far right side of the image.

Original image = Ha 10 x1200 1x1

Image B = LHaRGB

Image C - Enhanced the HII region in Holmberg IX area

Lum = 90 x 300 1x1

Red = 18 x 300 Red 2x2 + 10 x 1200 Ha (32%) 1x1

Green = 16 x 300 2x2

Blue = 18 x 300 2x2
