The one shot color balance seems to have missed on this one as it is way
too red on my monitor. Might be the very short exposure time. I used
50 minutes L and 45 RGB and it wasn't enough but it was a night of super
seeing which I've not had since so until I do I won't be redoing it.

With more exposure you should pick up Holmberg IX a very weird dwarf
galaxy the subject of one paper at the latest AAS meeting down Austin
way last week.

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