Well, this is my first attempt at actually processing an astro pic. M42 is a great first place to start. My problem was mostly an unbalanced scope, which has been fixed since the image was taken. The other common problem for M42 is the very large contrast between the bright core and the fainter filaments of the nebula. This is actually a stacked product of 5 images ranging from 30 seconds to 4.5 minutes. I stacked them using the free counterpart to Photoshop called GIMP. Seemed to do quite well. More processing was required in MaximDL. The camera is a modified Canon 30D and shot through an 80mm Vixen apo mounted onto an LX200GPS 14" Meade. The Meade was used to manually guide the exposures.
