Scope: Megrez II f/5.9 Location: Dos Picos Park, Ramona, CA 7 November 2008 Camera: Artemis285
Exposure: 12 x 8 min H-Alpha, 8 x 2 min RGB Exposures
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. 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 in PixInsight LE (SBNR). Final LRGB combine was done in Photoshop using Luminance Layering in LAB color Space. A light sharpening was applied to nebula regions. Final Image size is approximately 1092 x 1044.
All exposures in this image were guided; North is up in this image. Sharpless - 132 is a region of emission nebulosity in the constellation of Cepheus. The nebulosity is hydrogen gas excited to self emission by intense nearby stars. The Horizontal FOV is 64'.
Image center is located approximately - Equatorial 2000: RA: 22h 19m 51s Dec: +56°08'10"
