SDAA Club Site, CA, 22 July 2017
Camera: ST8300M (Baader Ha LRGB filters) Exposure:
Exposure: 12 x 8 min
(1x1 bin) exposure with IR/UV Block filter, 12 x 10 min (2x2 bin) exposure
with H-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. Images processed at 3352 x 2532 resolution. Final Image size is approximately
2600 x 1950. North is up in this image.
This general region of the sky (Constellation of Cygnus) has significant
emission nebula content Central in this field is the object from the
Dickel Wendker, and Bieritz catalog - DWB 192. It is also known as the emission
nebulae LBN 372, 375, 376. The region has a general pervasive
emission nebulosity. This image shows a small part of the very large Cygnus-X
region which we see as a tangential
view of the local spiral arm. The image shows the very northeast corner of Cygnus-X;
the upper third of this image lies outside of Cygnus-X. There are two other DWB objects
in this image. The star field is rich but there are likely a large portion of
stars obscured by intergalactic material. There is one dark nebula in this
field. These objects and a few bright stars are identified in the annotated
image. Horizontal FOV is 85' Image center is located approximately - Equatorial 2000: RA: 20h 36m 36s Dec: +48°00'30"
