Default ASTRO: NGC 157

This is another Herschel 400 object, a galaxy this time. It's also one I
never revisited since observing it for the list in the early 80's.
Seeing was poor and while it has several HII regions I should have been
able to pick up, seeing seems to have obliterated them. Halpha probably
would help as well. This will have to do for now. I couldn't find a
good distance estimate for this one but since it is a lone galaxy, not
part of a group the red shift distance of 60 million light years may be
somewhat in the ball park.

14" LX200R @ F/10, L=4x10' binned 2x2, RGB=2x10' binned 3x3,
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".

Great picture Rick. Makes me wonder how I managed to overlook this one so
far.

I have to correct myself, the galaxy is at -8 degrees, which is a good
reason to ignore it as I never get good detail on anything below the
celestial equator. So I have to change "great picture" to "very great
picture" (although this does not sound like a valid phrase).

Think I'm a bit further south than you (47 north) so have a edge with
southern objects. Still they never come out like those higher in the
sky! I usually cut off at -15 in summer. In winter a fog hangs over
the ice of the lake at night so I can't go as far south that time of the
year without lots of loss to the foggy conditions.
