Many of your galaxy shots ended up on my to-do list. Somehow I didn't
add this trio to the list though I saved it for future reference. They
are now. But imaging has to wait until this ice is out of the winter
sky. Faint arms just don't register with it. My background without the
ice and no moon is about 250 counts in 10 minutes, but with the ice in
the winter it runs to 8500. I might as well have a full moon nearby.
Sky looks dark but the CCD says otherwise. Actually once you are dark
adapted you see the glow but have to know what to look for, it isn't
obvious. Open clusters have to be my target if it ever clears up.
Light snow all day but it didn't amount to much, a foot is on the way
for tomorrow they say. Making up for last year.

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

lot of detail in the image.

color in the future?

John,

that's a neat group. Makes me wonder why I haven't imaged it yet.
