Processing: Data Collection - N.I.N.A. (as FITs).
Sub-frame calibration - Pixinsight (WBPP). Sub-frame registration and
integration (Average combine - Linear fit clipping, 2X drizzle
for Lum) - PixInsight (WBPP). Noise reduction - NoiseXTerminator
(RGB, Lum) - PixInsight. Non-linear stretching for Lum -
PixInsight. RGB combine and stretching, Photometric RGB calibration (SPCC)
- PixInsight. De-convolution - BlurXTerminator (AI4) - PixInsight.
Generation of starless Lum and RGB image for later processing -
StarXTerminator (PixInsight). Lum starless combined to RGB
starless; Lum stars combined to RGB stars - Pixinsight. LRGB stars screened onto
LRGB starless - Pixinsight. Final finishing - Affinity Photo.
Annotation - PixInsight, Aladin (Simbad), and Affinity Photo. This image is
an LRGB image. Image processed at 8288x5644 resolution (2x drizzle
stacks). Full Field image size is approximately 6155x4174.
Description: North to the right in this image. The
dominant galaxy is NGC 3079 - a Seyfert type 2 believed to have a wind driven
'super bubble' about it's center extending about 3,500 light years above
its galactic disc. Only the base of this bubble can be seen faintly on the top
side of the galactic disc in this image. Scientific images (from Hubble) show
the bubble extending upward about 3,500 light years.
Companion galaxies are NGC 3073 - about 59 million light
years, and
PGC28990 - about 67 million light years. More distant galaxies in this image are LEDA
2516941, 2519107, and 2519190 - all around one billion light years distant.
There are a number of other background galaxies visible in this image field. Many
of these background galaxies are seen more easily in the starless
mouse-over (isolated from the Milky Way galaxy stars). These objects,
information, and some of the brighter stars are identified in the annotated
image. This image
field is also rich in Quasars - many are fairly distant. The furthest
quasar visible in this image is SDSS J100132.00+554106.2 with a light
travel time (Lookback) of 11.51 billion years and redshift of
2.960. It is located somewhat central in the image and is below NGC
3079. A particularly interesting Quasar is Q 0957+561A - 9.197 billion
years light travel time (Lookback). The light of this Quasar passes near
a less distant galaxy, YGKOW G1 (and related galaxy cluster), that
gravitationally 'lenses' the light and creates an adjacent double image
of the Quasar (called QSO 0957+5608B). There is a separate Quasar
Annotation image.
The Horizontal Full FOV is approximately 0.667 degrees. Full
size, full field image scale is approximately 0.390 arcsec/pix.
