Scope: Explore Scientific MN152  Maksutov Newtonian at f/4.8, Location: Laguna Mountains, CA   16 August 2014  Camera: ST8300M

Exposure: Exposure: 16 x 8 min  (2x2 bin) exposure with H-Alpha, 8 x 8 min (1x1 bin) exposure with IR/Block, 8 x 4 min (2x2 bin) RGB exposures.

Processing: Data Collection -  CCDSoft (as FITs).  Calibrated, stacked (Sigma Kappa Combine) in Deep Sky Stacker, L - RGB channel registration, equalization, central gradient removal - Astroart.  Color calibration with eXcalibrator. Curves, Levels, and Luminance development, RGB combine - Images Plus.   Finishing  - Photoshop. All processing was done on 2x2bin data after up-sampling to 1x1 bin equivalent (3352x2532). This image uses  Luminance and H-Alpha data for a luminosity layer.  Development was an LRGB combine with Luminance layering L channel created as described.  Saturation in LAB color.   Final Image size is approximately 3352x2532 resized to 2600x1950.

North is to the right in this image.  The lower part of the field shows an object known as LBN 302. The dark nebula LDN 907  is right next to LBN 302. In the upper part of the image are two parts of TGU H497 (part P8 and P12). All of TGU H497 consists of 24 parts and the full structure extends North and East two degrees of arc. In this image is the parts of the furthest southwest extension; the other end of this dark cloud forms the "Gulf of Mexico" in the North American nebula.  The annotated image identifies these nebulae as well as some of the brighter stars.  Horizontal FOV is 88'

Image center is approximately - Equatorial 2000: RA: 20h 47m 02s Dec: +40°59'23"
