M101 Spiral Galaxy in Ursa Major

M101 on Jan 29, 2017. 23×60 sec @ ISO 800, TV-85 at F/5.6, Canon T3, Atlas EQ-G w/EQMOD.

Here’s one I have not shot in a while.   I was hoping it would come out better, but unfortunately, I lost quite a few of the sub-images to bad guiding.  I was supposed to get 40 or more, but only 23 were good enough to use.

UPDATE:

M101 with more time added. 64×60 @ ISO 400 and 23×60 @ ISO 800 or 87 minutes total.

I was able to shoot this again and get lots more sub-images.   Not too bad considering the light pollution that I had to endure.
