Camera: ST8300M (Baader LRGB filters) Exposure:
Exposure: 16 x 12 min
(1x1 bin) exposure with IR/UV Block 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 IR/UV Blocking filter exposure stack
was used for the
luminance layer. Images processed at 3352 x 2532 resolution. Final Image size is approximately
2600 x 1950. North is to the
left in this image. vdB 123 is a reflection nebula in a spur region of the
Milky Way's Great Rift. The Great Rift is a swath of dark lane in our galaxy's
plane that is shrouded in dust and interstellar matter. vdB 13 is the middle
blue nebula - center left; its embedded star is HD 170634. The little red nebula
just above it is known as the Serpens Reflection Nebula - it is a heavily
studied object because of its young age and star formation taking place within
it. Also nearby Upper right is the Serpens G3-G6 Star Cluster - another star
forming area. The interstellar matter of the Rift creates a number of dark
nebulae. There are 14 dark nebulae in this field from the Dobashi catalog - nine
of these larger clouds are noted in the annotation. These objects are identified in the
annotated
image. Horizontal FOV is 85' Image
center is approximately - Equatorial 2000: RA: 18h 30m
