Scope: FSQ-106N at f/5, Location: DAA Observatory, Shelter Valley, CA 16 February 2018,  Camera: Atik 383L (Astronomik Gen 2 Ha LRGB Filters)

Exposure: Exposure: 8 x 9 min  (1x1 bin) exposure with UV/IR block, 6 x 10 minutes (2x2 bin)  exposure with Hydrogen Alpha filter, 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, equalization and gradient removal - Astroart.  Curves, Levels, RGB combine - ImagesPlus. Luminance Layering, final stretch, and finishing  - Photoshop.  RGB calibration - eXcalibrator. This image is a  RGB combine with Luminance layering.  Color saturation in LAB color.  The H-Alpha filter exposure was screen blended into the IR/UV Blocking filter exposure stack and used for the luminance layer. Ha was screen blended into the Red channel -  emission balance of RGB done with Channel Mixer in Photoshop. Images processed at 3352 x 2532 resolution. Final Image size is approximately  2600 x 1950.

North is up in this image.  The large red emission nebula is part of LBN 1059 which is a part of the larger yet Sharpless 310. This field covers less than half of the LBN 1059 structure. LBN 1059 is ionized by two stars - 29 CMa and 30 CMa - both of which are off of this field to the lower right. The Sharpless 310 emission structure is one of the largest single HII regions in the Milky Way. The blue reflection nebula is van den Bergh 96 - also cataloged as LBN  1058 and CED 96 (parts a, b, c ). The small dark smudge in vdB 96 is a grouping of Herbig-Haro objects (all parts of HH 92).  There are several dark nebulae in this field - the most visually apparent is LBN 1660 just above vdB 96. This field also contains three open star clusters - Trumpler 6,  Ruprecht 17 and Milky Way Star Cluster  (MWSC) 1215.  These objects  and some of the brighter stars are identified in the annotated image.  Horizontal FOV is approximately 120 arc minutes.

Image center is approximately - Equatorial 2000: RA: 07h 22m 21s Dec: -2345'42"
