ASTRO: Pegasus II Galaxy Cluster

The Pegasus II galaxy cluster, not to be confused with Pegasus II the
galaxy, contains some 175 galaxies over a field about 4 times larger
than I can image. I've just picked up the central, densest, part. The
three main galaxies are all giant ellipticals. It is normal for giant
elliptical galaxies to anchor large clusters like this one. Left to
right they are NGC 7530, NGC 7501 and NGC 7499. The cluster is thought
to be about 550 million light years away. The area of this image shows
bright in X-rays as seen by orbiting X-ray satellites. This would
indicate there's a huge cloud of very not gas in the core region of this
cluster, it has likely been stripped from galaxies combining to form the
three major members of the cluster. The near edge on (maybe S0) galaxy
is MGC+01-59-003 while the face on barred spiral below and to the right
of it is MGC+01-59-002. It is NOT a member of this cluster however with
a distance of about 197 million light years, much closer than the cluster.

Three asteroids are in my image. None are easy to see due to my
severely limited ability to see faint objects thanks to all the snow in
the air and on the ground right now. From left to right they a 2005
XL56 magnitude 19.2, (191343) 2003 QF33 magnitude 18.8, and 2008 QG22
magnitude 18.7. The latter appears far fainter than the others. So it
appears the estimated magnitudes I got from the Minor Planet Center are
off, at least with respect to this last one.

14" LX-200R @ 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!
