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.
