Over 26 hours of data combined to
make this colorful image of NGC
7793, a galaxy in the Sculptor group,
about 12.5 million lightyears distant.
It is the first image produced by
SSRO-South after a long hiatus,
during which extensive
reevaluation, testing, and tweaking
was done of the mount and
software in an attempt to improve
the FWHM and aspect ratio of the
images. The master LRGB
subframes in this image have
FWHM of 1.3-1.5" and aspect ratios
of 5 or under.

NGC 7793 has a microquasar in one
of the outer arms. The jets coming
out of this system are seen as a
small bright red triangular-shaped
area (with a dimmer shell
surrounding) in the lower portion of
our image, to the left of center. The
area is enlarged in the inset. Please
