COMMENTS
This is one of my first H-Alpha images. Something went wrong during the stacking process that left
the resulting image in that "shaky" state. I'll probably try to stack it using MaximDL or CCDStack and see
if things improve. I don't really dislike that uninvited effect, other than it leaves the image ressembling
a painting more than a photography. It was comforting however to see how much H-Alpha can the modified 40D
capture. With an unmodified DSRL this would have been impossible.
