Hi folks
this image should have been finished prior to my recent M51, but I have been unable to reveal Arp's Loop, despite many hours of exposure, without adding significant noise. This really ruined the image, so the version here crops that out. I will now have to wait until next season to get an extra 10-15 hours to do it justice. I do have a version showing it, but as I say, it spoils the fine data in the main galaxy.

Acquired from Heaven's Mirror Observatory in the Sierra Nevada, this is a HaLRGB image comprising 7hrs 40mins:9hrs 40:4:4:4 hours.
Hope you like it as much as M51
Cheers and thanks for checking it out
Martin
