ON IMAGE FOR FULL SIZE VIEW (2800x2100) Scope:
FSQ-106N at f/5, Location: Laguna Mountains, CA 8 August 2015
Camera: Atik 383L (Astronomik Ha LRGB filters) Exposure:
Exposure: 12 x 6 min (1x1 bin) exposure with IR/UV Block filter, 12 x 10 min
(2x2 bin) H-alpha exposures, 8 x 4.5
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
central gradient removal - Astroart. Curves, Levels, RGB combine -

This image is a RGB combine with Luminance layering. H-Alpha
exposure stack was screen blended into the wide spectrum IR/UV block stack for
the Luminance channel; the H-Alpha stack (nebula feature only) was lighten
blended into the Red stack for the Red channel. Color
saturation in LAB color. Final Image size is approximately 2800 x 2100 North is up in this
image. Central in this image are the Nebulae LBN 437 (bright nebula) and
LBN 428 (emission nebula). LBN 428 is also cataloged as Sharpless 126. These two
nebulae overlap each other. The smoky, dusty colored nebula is LBN 437 and the
red emission nebula is LBN 428 / Sharpless 126. In addition to these nebulae,
there are several noticeable background galaxies at distances estimated by
redshift at up to 783 million light years distant from Earth. LBN 437 also has
the variable star V0375 Lac and an associated reflection nebula GN 22.32.5.
V0375 Lac is a Herbig Ae/Be star - there is a distance reference in Simbad
of about 2,870 light years; other distance estimates are shorter - down to
1,960 light years . Sharpless 126 is estimated at about 1,700 light years
distant from Earth.These objects , background stars and a few bright stars and
identified in the annotated
image. This image replaces an earlier image in the Archives
here. Horizontal FOV is 116' Image
center is approximately - Equatorial 2000: RA: 22h 33m
