Description

The Pinwheel Galaxy photographed from a Bortle class 5 area in the southern part of Sweden. Data acquired during 2 nights with very good conditions (for this place).

The image is kept "a bit warm" on purpose. I did test to cool it down a bit, but I liked the contrast of the dark sky vs the cold-blue arms of the galaxy. I also kept the galaxy slightly off-centered, as I did not want to cut away the small galaxy cluster in the upper left corner.
