Description

This is a little less than 10 hours of LRGB + Ha data. M81's faint satellite galaxy, Holmberg IX, is visible. I have also uploaded an overstretched luminance image and if you use your imagination and look for the black arrows you may be able to detect Arp's loop (see Bill and Chad William's image https://www.williamsseaandsky.com/?page_id=6354  and the paper by Sollima et al. in Astronomy and Astrophysics, 516: June-July 2010, http://www.aanda.org/articles/aa/pdf/2010/08/aa14085-10.pdf )
