Scope: FSQ-106N refractor at f/5, Location: Blair Valley, Anza Borrego Desert, CA  26 December 2013  Camera: ST8300M

Exposure: 12 x 12 min  (1x1 bin) exposure with UV/IR block, 8 x  12 min (2x2 bin) H-Alpha exposures, 8 x 3 min (2x2 bin) RGB exposures.

Processing: Data Collection -  CCDSoft (as FITs).  Calibrated, stacked (Sigma Combine), L - Ha - RGB channel registration, equalization, central gradient removal - Astroart.  Curves, Levels, L - Ha - RGB combine and finishing  - Photoshop. Final color Calibration with eXcalibrator. This image is UV/IR Block and Ha blend for the Luminance channel and then a LRGB combine with Luminance layering.     Final Image size is approximately 3352x2532 resized to 2400x1800.

North is up in this image. Barnard 30 and 31 are the dark regions in the upper part of the image. Barnard 32is the darker area around the central blue reflection nebula. The emission region is not separately cataloged but is part of the much larger (6.5 degree spanning) Sharpless 264 emission nebula. The center of Sharpless 264 is well off the image to the lower left. The dark regions consist partially of  hydrocarbon modules. They are roughly 1,300 light years distant.  Horizontal FOV is 115'


Image center is approximately - Equatorial 2000: RA: 05h 31m 28s Dec: +1221'34"
