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: +12°21'34"
