Celestron 9.25 Edge 235 mm at f/7, Location: Blair Valley, Anza Borrego Desert, CA
10 October 2015 Camera: ST8300M (Baader LRGB filters) Exposure:
Exposure: 20 x 10 min (2x2 bin) IR/UV block exposures; 8 x 4.5 min (3x3 bin) RGB exposures. Processing: Data
Collection - Sequence Generator Pro (as FITs). Calibrated, stacked
(Sigma Kappa Combine) in Deep Sky Stacker, L - RGB channel registration,
equalization, central gradient removal - Astroart. Curves, Levels, and
Luminance development, RGB combine - Images Plus. Finishing - Photoshop.
Color calibration with eXcalibrator. This image uses UV/IR Block for the Luminance
channel and then a LRGB combine with Luminance layering. Saturation in LAB
color. Final Image size processed at approximately 3352x2532 cropped
and resized to 2400x1800. North is up in this
image. This field is dominated by the galaxy IC 342. This is a spiral
galaxy (morphology SAB(rs)cd). This morphology is interpreted as an intermediate
spiral / barred galaxy with a weak ring and loose, somewhat clumpy spiral
arms. It is in an area of the sky where its light experiences some
extinction as it passes through obscuring Milky Way dust and galactic material.
There are two other galaxies detectable in this field. - one to the left of IC
342 (LEDA 166480) and one in the upper right corner (UGC 2826). These galaxies as well as
IC 342 and some of the brighter stars are identified and highlighted in
the annotated image. IC342
is relatively close at about 11 million light years distant; UGC 2826 is
about 68 million light years distant. This image replaces an earlier image
that can be seen in the Archives here.
