M81, Ursa Major, 8"LX200 f3.4, MX7C, IDAS, 180min

This image of M81 was taken over several nights from my backyard observatory in Ocean Springs, MS.  Due to some serious light
pollution to the north of my observatory, a significant amount of exposure time was needed.  (60) unguided hires progressive exposures were combined with (30) 240sec star2000 guided exposures.  Processing was done with Astroart and AIP4WIN. Final balancing and layering
with Photoshop.
