I got thinking later (after the clouds rolled in) that I should have
done that for the lum image. But at the time I didn't know it was
mostly dust we were seeing not gas. That's usually so far out of the Ha
passband to be invisible.

I leave for a few days starting tomorrow so can't follow it but then the
clouds are to be back so it doesn't much matter.

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

Richard, with your Halpha shots you'll probably be the first to discover a
HII region in a comet ;-)
