M101 galaxy : new PP

As the weather is really bad, I'm trying new post processing on some old photos.

There is a lot of galaxies around M101, at least 10 in the field.

NGC 5474 on the left , dwarf galaxy , M=11 , d=21Mly

NGC 5422 on the right, M=12, d=19Mly

NGC 5443 on the right border, M=12.3, d=83Mly

NGC 5477 just over M101, M=14, d=14Mly
