M81 and surrounding IFN

[Gabrielwiklund]

M81 is one of my favorite galaxies so i could not resist capturing it a second time this season now when the skies cleared up after almost 1 month with clouds.

Captured November 16th,17th and 18th. Total integration time: 16 hours and 42 minutes.
The reason i cooled my camera to -30°C is because ambient temp during capture was between -15°C and -20°C.
