ASTRO: NGC 1999 and surroundings

Another cloud terminated image. I got some pretty good H alpha data but
when I went for color I got only one green frame -- with a bright
satellite and one blue -- also with that same satellite and another
satellite (geo-stationary I believe as it makes a directly east west
path). I got no red data as the clouds nailed me so used the H alpha
channel for that making for some odd blue stars as they hardly register
in H alpha. With all the clouds of late I doubt I'll get more color
data so going with this as it is now galaxy season. NGC 1999 is the
blue white reflection nebula near the center that looks much like a
keyhole -- to the heavens as some say. The "hole" is really a really
shadowed area, not a hole at all.

The red is part of the faint general H II cloud that covers much of the
constellation of Orion. The two red "stars" below NGC 1999 are two
Herbig Haro regions per Richard Crisp's web page showing a wide field
view using his narrow band approach.

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

now there's one that I actually have shot before Rick: both in Halpha and
also in my weird "hubble palette" using [SII]/Ha and [OIII]

here are my versions:

halpha only

tricolor emission line:

it looks pretty disgusting in emission line filters I think

This is my earlier attempt solely directed toward the nearby "waterfall"
(HH222 and HH34)

http://www.narrowbandimaging.com/her...ro_34_page.htm

and a bit later attempt using the Stinger 450 Cass, but with lousy seeing
and poor signal strength (not enough exposure time on that puppy)
http://www.narrowbandimaging.com/hh2..._csha_page.htm

as you can tell I really like that region and someday I hope to actually
take a good image in that area :-)

Very nice deep shot. I imaged NGC 1999 twice, but never even noticed that
there is an emission part around the reflection nebula. I'd probably need a
Halpha filter to record the emission part as it seems to be quite faint.
