IC 1318A (Northwest) in Cygnus



Scope: Explore Scientific MN152 Maksutov Newtonian at f/4.8, Location:  Laguna Mountains, CA   8 August 2015  Camera: ST 8300M

Exposure: Exposure: 12 x 6 min  (1x1 bin) exposure with UV/IR block,  12 x 10 min (1x1 bin) H-Alpha exposures, 8 x 4.5 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 central gradient removal - Astroart.  Curves, Levels, RGB combine Images Plus. Luminance layering and finishing  - Photoshop. This image is a  Ha LRGB combine with Luminance layering. The H-Alpha exposure stack was screen blended to the Luminance exposures  to form the Luminance layer.   Color saturation in LAB color;    Final Image size is approximately 2800x2100.

North is up in this image. Central in this image is the emission / reflection nebula IC 1318A, also known as  DWB 82 and LBN 251. This region is in Cygnus and is part of the larger IC 1318 emission nebula known as the Gamma Cygni Nebula. There are also two other objects from the DWG catalog (DWB 78 and DWB 83). There is a minor star cluster known as BD +40 44124 Cluster in the lower left corner. There are several other Lynds Dark and Lynds Bright nebulae in this field as well (LBN 239, LBN 259, LDN 891, LDN 892, LDN 894). These objects and some of the brighter stars are identified in  the annotated image.   This region's emission nebulosity is generally regarded to be about 5,000 to 5,500 light years distant from Earth. This image replaces earlier images that can be seen in the Archives here and in the Archives here.  Horizontal FOV is 85'

Image center is approximately - Equatorial 2000: RA: 20h 16m 57s Dec: +4149'17"
