Description

Another shot from Convict Lake. Total exposure here is quite amazingly short, though I've glossed over some noise in the dust with the noise reducer, and it was binned 2x2. I didn't have much time to shoot it, actually, because it only just rose over the hill in the south not long before dawn was creeping in.

This is an HDR shot. The range in this shot was the primary difficulty in processing it -- preserving the core at the same time as seeing the dust requires some careful masked stretches.

Also, I have adjusted the color of the main portion of the nebula to be more DSLR-like. I think this better accentuates the interesting color contrasts in the nebula. I left the background dust its natural color.
