Astro: A Cepheus Planetary NGC 7139

Milky Way wasn't quite as dense in Cepheus as it is was in Cygnus for
NGC6894. Still it makes for a nice setting. Note that most of the red
ring is due to NII not HII though there is some HII. The NII line is so
close to HII a 3nm filter is needed to separate the them. This however
is just a LRGB image.

14" LX200R @ f/10, L=4x10' binned 2x2, RGB=1x10' binned 3x3 (clouds
prevented a second set of color frames and this seemed sufficient so
never went back for more), STL-11000XM, Paramount ME

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