M51 Spiral Galaxy Red Zone Image

M51 on Jan 24, 2017. 40×60 sec @ ISO 400, TV-85 at F/5.6, Canon T3, Atlas EQ-G w/EQMOD.

Another Bortle Red Zone image with a relatively short exposure of 40 minutes in 1 minute subs.   I have another batch of 1 minute subs taken at ISO 800 to add to this, but here is the preliminary image for the time being.

Update:

M51 on Jan 24, 2017. Close-up crop. 40×60 sec @ ISO 400 and 40×60 sec @ ISO 800, TV-85 at F/5.6, Canon T3, Atlas EQ-G w/EQMOD.
M51 Full Frame.

The additional 40×60 sec @ ISO 800 subs-images are added into the mix and the updated full frame image and a close-in crop are above.   🙂

Just for fun, I added the above image with 2 previous images of M51 taken with bigger scopes and the results are below:
