Great work and good balance between lines.
I like the color scheme a lot, not too vivid, as I tend to have.

Very nice! That squirly dust lane in the upper left is awesome. It looks like the nebula was signed by the artist.

yes, both HST but the polite version (this one) has proper combine weights (that was hard to estimate from different lenght subexpositions - data captured over 6 nights with/out Moon and on different places)

Fantastic! Especially considering the fact that you captured it from different sites.. Doing a 6 night exposure is tough, even from a fixed observatory... Doing it from different sites must be a real mission!

Great payoff for the dedication!

i'd always thought the hst weighting was someone arbitrary
how do you determine the proper combine weights?

Trial and see :-) If I ever knew. Every image needs different processing :-/
