Scope: FSQ-106N at f/5, Location: Laguna Mountains, CA   16 August 2014  Camera: Atik 383L

Exposure: Exposure: 14 x 10 min  (2x2 bin)  and 2 x 10 min (1x1 bin) exposure with Hydrogen Alpha filter, 8 x 4 min (2x2 bin) RGB exposures.

Processing: Data Collection -  Artemis Capture (as FITs).  Calibrated, stacked (Kappa Sigma Combine) - Deep Sky Stacker. LRGB channel registration, equalization, and central gradient removal - Astroart.  Curves, Levels, RGB combine - ImagesPlus. Luminance Layering, final stretch, and finishing  - Photoshop. This image is a  Ha- RGB combine with Luminance layering.  Color saturation in LAB color; H-Alpha exposure stacks were used for the luminance layer.   Processing was in up-sampled  data (to simulate 1x1 bin). Final Image size is approximately 2600 x 1950.

North is to the right in this image. In this image the LBN 265 region and is dominated by that emission nebula and is central in this image. In addition, LBN 247, 263, and 277 are also in this image (at least partially. There are dark nebulae as well - LDN 896, 898 and TGU H491, H476.   These objects  as well as some of the brighter stars and a Cepheid variable star are identified in the annotated image.   Horizontal FOV is 120'

Image center is approximately - Equatorial 2000: RA: 20h 42m 52s Dec: +3910'51"
