Description

The whirlpool galaxy, in my opinion one of the most spectacular object in the sky.
I used a cloudless night to capture the image however since it was quite humid some dew formed on my secondary mirror which spoiled the results a bit. Also the dec-axis wasn't going so well, I definitely have to tweak that.
