Default ASTRO: The Blue Snowball

It wasn't the best night for shooting small objects but...I take what I can
get. For this object less is more. The longer exposures tend to blow the
inner arc out and flattens the look of the nebula. This is a 1 minute worth
of data with 2 subs taken through my C-11 @ f/10 with the Canon XTi @
800asa.

I've tried it a few times but seeing never was up to it here. When
seeing is good I have other targets that I seem to go to instead.

What is the bit depth of the XTi?

Processing some objects can be a challenge. I have more trouble with
faint ones going flat on me if I try to push too far into the faint
region. I can do it but it takes time to find the right curves to use.

Correct domain name is arvig and it is net not com. Prefix is correct.
Third character is a zero rather than a capital "Oh".

Nice picture. This nebula is bright enough to look good in short exposures.
