Wade - I think that is great! The only thing I can offer that might bring
out the nebula and the comet a bit better would be to use the lasso tool to
select the nebulae, feather the selection, then use curves to bring the red
channel up. Repeat with the comet but use curves to bring up the blue and
green.
