Description

A 7.5 hour integration on M81/M82 with a stock Nikon D5300, shot over two nights during a first quarter moon, from near Cobourg, Ontario. I was happy to see a bit of the IFN show through with this target, however in my original attempt at processing it, the data was heavily stretched to make the nebulosity pop, and I felt the image degradation wasn't worth it. So I've settled on a more subtle look. It's there, you just have to look a little harder
