Scope: Zenithstar 66 mm at f/4.5, Location: Tierra Del Sol (SDAA site), CA 10 September, 2010, Camera: Artemis285
Exposure: 7 x 8 minutes Luminance exposures (1x1), 8x8 minutes H-Alpha (1x1), 7 x 3 minutes RG Exposures (2x2), 5 x 3 minutes B Exposures (2x2)
Processing: Images were captured with Artemis Capture (as FITs). Aligned/stacked and dark subtracted in Astroart with Sigma Combine. H-Alpha and Color channels were scaled and color balanced in Astroart. Channels were co-registered in Astroart. Luminance construction consisted of the H-Alpha exposure blended with the luminance exposures. Curves and Levels applied in Photoshop to the Luminance construction to optimize object features. A light background noise reduction was applied to the Luminance construction . H-Alpha was blended with the red channel 80/20. Final LRGB combine was done in Photoshop using Luminance Layering. A light sharpening was applied to the final image. Final Image size is approximately 1392x1040. (Cropped to 1367x1021)
North is up in this image. This is a combination dust obstruction and faint hydrogen emission complex. The red areas are H-Alpha emission; the brown areas are interstellar dust. It is catalogued by as a Lynd's Bright Nebula - LBN 437. This region is located in the constellation of Lacerta. The Vertical FOV is 105'.
Image center is located approximately - Equatorial 2000: RA: 22h 32m 10s Dec: +40°36'05"
