Description

M51 shot during several nights. After a lot of frustration because of high clouds, fog and a full moon (I shot the Ha data at that time) I had to throw away 6 hours of data out of a total of 18 hours. In this final result I left out the 10 x 10 min of luminance because the HaRGB-data was good enough.
