Description

Two colliding galaxies - always a breathtaking view! For this Messier object I spent a lot of time on the luminance exposures. M51 shows a completely surrounding halo, much fainter than the one around NGC 5195, but still clearly visible.  

Furthermore, I stacked the unused luminance exposures separately and did not use an algorithm to remove the trails of planes and satellites. Revision B shows the unprocessed stack, which was stretched for viewing only. Sometimes there's a scary amount of stuff going on up there....
