Description

Here's a work in progress.  Dave Schaeffer and I are doing a collaboration on several Galaxies, starting with M81 & M 82.  I just took the data on M 81 to see what I could get out of it.  Dave took all of the RGB and a lot of Lum and Ha (I haven't added the Ha to this yet), I've just been concentrating on Lum with my NP127is/ASI6200MM.   This is an EXTREMELY cropped image, but I wanted to see if it would hold up to a heavy crop.  Unfortunately, I don't know, as of now, exactly how many subs are included....I do know that they are all 300s, and I would estimate there's about 250 LRGB.
Anyway, hope ya like it!
Tom
