LBN 315 Region in Cygnus



Scope: Explore Scientific MN152  Maksutov Newtonian at f/4.8, Location: Laguna Mountains, CA   20 July 2014  Camera: ST8300M

Exposure: Exposure: 16 x 10 min  (2x2 bin) exposure with H-Alpha,  8 x 4 min (2x2 bin) RGB exposures.

Processing: Data Collection -  CCDSoft (as FITs).  Calibrated, stacked (Sigma Kappa Combine) in Deep Sky Stacker, L - RGB channel registration, equalization, central gradient removal - Astroart.  Color calibration with eXcalibrator. Curves, Levels, and Luminance development, RGB combine - Images Plus.   Finishing  - Photoshop. All processing was done on 2x2bin data after up-sampling to 1x1 bin equivalent (3352x2532). This image uses RGB synthetic Luminance and H-Alpha data for a luminosity layer. Red channel was a blend of red and H-Alpha. Development was an LRGB combine with Luminance layering creating L and R channels as described.  Saturation in LAB color.   Final Image size is approximately 3352x2532 resized to 2800x2100.

North is up in this image.  The full field shows an object known as LBN 315. The object LBN317 embedded in the structure. The DWB catalog has several entries for this field; DWB 150, 151, 155, 157, 158, 159, 162, 163, 164, and 169. This region is part of a larger region known as Cygnus-X. which is a massive star forming region about 4,600 light year distant on average. It is a region containing the largest number of massive proto-stars. The annotated image identifies these nebulae as well as some of the brighter stars.  Horizontal FOV is 88'

Image center is approximately - Equatorial 2000: RA: 20h 31m 29s Dec: +4417'06"
