Description

The Pinwheel galaxy is located 21 million lightyears away and is 170 000 lightyears across. It's size and shape is similar to the Andromeda galaxy.
For once I had the unusual case of sunday night, no clouds and a slight breeze that prevented all dew. A long dark night with exellent conditions gave me this image.
