Description

This is the luminance part of the M51. I hope I will get the time and the weather will allow me to also get the color data in the next days

Revision B: because the previous version was processed on an uncalibrated display, I did not see all the "garbage" in the background :-) This revision corrects that, although the halo around M51 is a little less visible.

Revision C: a bit of work on the dimmer stars.
