Default ASTRO: Comet Holmes

Comet Holmes (P/17) in Perseus suddenly went from 18th magnitude to 3rd.
It's easy tonight naked eye even with the moon though looks pretty
starlike to me, even in 7x20 binoculars. Takes the 10x50s to show the
coma. The dang core so staturated me CCD that in only 1 second it was
blooming my antiblooming chip!! So this is a series of half second
exposures. Yeah, half second. I used 11 of them and 4 each of one
second color images. I expected green, I got reddish creme instead.
Moonlight? This is through high cirrus which are quite bright in the
moon. I need Stefan to process this.

Delta is the distance from us, R from the sun so this guy is way out there.

Your image looks pretty much like what I've seen in my 20x80 binoc's. The
color looks OK to me, but then I'm partially color blind.

Hoping for a lot from this comet.........

Nice one. Looks like a planetary nebula.
