CLICK ON IMAGE FOR FULL SIZE VIEW (2600x1950) Scope: FSQ-106N at f/5, Location: DAA Observatory Shelter Valley, Anza Borrego Desert, CA 28 January 2017 Camera: Atik 383L (Astronomik Gen 2 Ha LRGB Filters) Exposure:
Exposure: 14 x 8 min (1x1 bin) exposure with UV/IR block, 12 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 to the
right in this image.
The open cluster NGC 2353 is central in this field. LBN 1036 extends to the
upper left of NGC 2353. To the upper right is the emission nebula Sharpless 294
- also known as LBN 1032. Also included in this field is the Group of Stars
identified as NGC 2351. There are several notable dark nebulae and some
substantial non-cataloged nebulosity. T These objects are identified in the
annotated
image. Just outside and below the image field is the well known Seagull
Nebula (IC 2177). The open Cluster NGC 2353 is about 3,649 light years distant.
