Scope: FSQ-106N at f/5, Location:  Pine Creek, Laguna Mountains, CA   1 October 2016  Camera: Atik 383 (Astronomik Gen II  LRGB filters)

Exposure: Exposure: 12 x 7 min, (1x1 bin) exposure with UV/IR block, 14  x 10 min (2x2) exposure with H-Alpha, 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 and equalization, rough color calibration  - Astroart.  Curves, Levels, RGB combine - Images Plus. Luminance layering and finishing  - Photoshop. This image is an LRGB combine with Luminance layering. The H-Alpha exposure was screen blended into the IR/UV Block exposures to create the Luminance channel. Final color calibration - eXcalibrator. Color saturation in LAB color. Native image size - 3354x2529.  Final Image size is approximately 2800x2100.

North is up in this image. This field is the IC 59 and IC 63  Region and lies in the constellation of Cassiopeia.  IC 59 is a reflection nebula with some emission and has other catalog entries of LB 620 and CED 4b. IC 63 is primarily an emission nebula and has the additional catalog entry of CED 4a. The overall emission complex consisting of IC 59, IC63, and surrounding nebulosity is known as Sharpless 185  and as LBN 622. The very bright star is commonly known as Navi or Gamma Cas. Navi also illuminates some of the immediately surrounding interstellar material and has a designation in the van den Bergh  catalog of vdB 5. in the opposite corner of the image is the open cluster NGC 381 and is also known as Collinder 10. There are some dark nebulae in this field as well as an additional LBN object - LBN625. These objects as well as a few of the bright stars  are identified in the annotated image. This image replaces an earlier image that can be accessed from the Archives here.   Horizontal FOV is 120'

Image center is approximately - Equatorial 2000: RA: 01h 03m 37s Dec: +6104'29"
