Image size is approximately 4000x3000. North is up in this image. The
spiral galaxy in the lower left is NGC 7479 - a Seyfert type 2 SB(s)c
galaxy - sometimes called the "Superman Galaxy". It's distance is
comparable by independent estimate (82 million light years) and by redshift estimate
(92
million light years). This image also shows the molecular clouds in this region
of the sky. Some of their structure is cataloged in the Planck Catalog of
Galactic Cold Clumps (PGCC). This field has numerous background galaxies -
a few are visible in this image. Many are obscured by the intervening galactic
material from the Milky Way. Some Quasars are also visible in this image
but many are obscured by the galactic material as well. The visible Quasars range from
1.67 to 12.0 billion light years lookback. These objects,
information, background galaxies and some of the brighter stars are identified in the
annotated
image. Horizontal FOV is approximately 85 arc minutes. Full size
image scale is approximately 1.27 arcsec/pix.. Image center is approximately - Equatorial 2000: RA: 23h 02m 35s Dec: +12° 40' 40"
