Bode's Galaxy for coma test

There is a great supernova exploding in the M82 galaxy, but very close to M82 there is M81 Bode's Galaxy. Last night when I shot supernova SN2014J I also exposed a few sample frames of M81 which is about 12 million light years away. The transparency was very poor (naked eye limit was about 4 mag) but seeing was pretty ok and it was a good chance to test Baader MPCC Mark III coma corrector. That's how the picture below has been created.
It is a stack of 7 exposures for 3 minutes. The picture scale is 1.5"/px and all looks pretty ok, so I can recommend this corrector for astrophotography. 

Clear skies!
