1 October 2016
Camera: ST8300M (Baader Ha LRGB filters) Exposure:
Exposure: 15 x 10 min
(1x1 bin) exposure with IR/UV Block filter, 10 x 10 min (2x2 bin) exposure
with H-Alpha filter, 8 x 4 min (2x2 bin) RGB exposures. Processing: Data
Collection - Sequence Generator Pro (as FITs). Calibrated, stacked
(Kappa Sigma Combine) - Deep Sky Stacker. LRGB channel registration,
equalization, and gradient removal - Astroart. Curves, Levels, RGB
combine - ImagesPlus. Luminance Layering, final stretch, and finishing -
Photoshop. RGB calibration - eXcalibrator. This image is a RGB combine
with Luminance layering. Color saturation in LAB color. The H-Alpha
filter exposure was screen blended into the IR/UV Blocking filter exposure stack
and used for the
luminance layer. Images processed at 3352 x 2532 resolution. Final Image size is approximately
2800 x 2100. North is up in this image.
The central attraction in this image is the emission / reflection nebula known as
NGC 1579. It is also known as Sharpless 222, Cederblad 35 and LBN 767.
There is a dark nebula region roughly extending North to South - this region
contains several objects identified in the Dobashi Catalog of Dark Clouds. To
the upper left of the NGC 1579 nebula is a smaller blue nebulosity having an
Index Catalog entry as IC 2067. It is entered as a Inter Stellar Matter object -
to me, it seems like a reflection nebula. There
are a few background galaxies in this field as well. These objects are identified in the
annotated
image. . Horizontal FOV is 85' Image center is located approximately - Equatorial 2000: RA: 04h 30m 12s Dec: +35°16'00"
