Markus Breidenich, Tim Valder
One of the most beautiful spring galaxies, the Whirlpool galaxy M51 in Canes Venatici, has been recorded by Markus Breidenich with a Skywatcher 254/1200 reflector and a Canon EOS 450 camera, manual guiding with an ED80 guidescope. Four images with 5 minutes exposure time have been stacked. Image processing with Fitswork and Photoshop was made by Tim Valder.
