Last night I decided to put some time on M81 and M82. Dimmer than M42 so it
was more of a challenge. Once again, I used my Canon 60 DA digital camera and
did 44 x 300 second exposures with the 6nm Astronomik light pollution filter.
This was imaged from my home, 7 miles from the airport. I wish I could get a
filter like that for my FLI CCD camera. Here’s a link.

I wonder if your composite image shows Holmberg IX,
the dwarf irregular galaxy over on the east (right-hand) side
of your image. It might come out a little if the sky
background were medium-gray rather than black.
The double star southwest of M81 (upper-left)
has about 9" separation. The brighter star near it
is also double, at about 2" separation.
