This is the result of 43 stacked frames from my 350D - ranging from seconds to minutes and over several months'-worth of sessions, merged with the monochrome frames I took recently with the SBIG ST-8i for a little extra luminance. Detail is starting to show quite well, but I've left it in a high-contrast state to highlight it. Now's my chance to really knuckle down and take some really long exposures and get as much data as I'm comfortable spending an afternoon dealing with.
All done in Photoshop CS3, including merges, stacks and hand-alignments.

Second image is an HDR merge of the same source files minus the SBIG frames - hence the larger FOV.
