NGC 1579 Region in Perseus



Scope: Explore Scientific MN152 Maksutov Newtonian at f/4.8, Location: DAA Observatory, Shelter Valley, CA,  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: +3516'00"
