Canon 500D camera with EF-200/2.8L lens on EQ6 equatorial mount guided by a QHY5 camera and PHDGuiding. Stacked 5 frames in Deep Sky Stacker, total exposure ca 5 minutes. Shot on Sat-Sun night 23-24 Jan 2010 in cool -18 C but calm weather. Would have wanted longer exposures and more frames, but the guiding wasn't working very well, and Orion is pretty low, hiding behind trees from my site. The dark thing on the right is a tree 🙂
Same image but cropped:
A nice improvement over my 2008 December attempt on M42.
