Default ASTRO: M101

My "project galaxy" this spring was M101, trying to improve upon an image I
took under good skies in 2005 with my old 8"LX200. With better equipment and
three times more exposure time the new image is indeed better than the old
one.
I imaged M101 in four nights and got about 9 hours for luminance and a bit
more than three hours for RGB (colour version will follow).

Taken from the middle of Berlin with a 10" Meade ACF at f/5.7 on a G11
mount, SXV-H9 camera, 109x5 minutes.

The picture can also be found at

And the old picture for comparison:
