Description

44x12min = 528minutes

astromod canon 50d, astronomik CLS filter

classic celestron C8 with 0.63x reducer, fl=1260mm, f/6.3

processing with pixinsight 1.6.9

most of the subs here are at a camera temperature of 6-7C. still a little disappointed with the noise levels in the fainter areas of the galaxy. i guess that's what i get for shooting in urban skies.

tracking could be better...

edit: i boosted the saturation and the blues/reds and pulled the greens down a little based on other pictures of m101. looks a bit better maybe.
