CLICK ON IMAGE FOR FULL SIZE VIEW (2800x2100) Scope: Explore Scientific MN152 Maksutov Newtonian at f/4.8, Location: DAA Observatory, Shelter Valley, CA, 23 May 2020, Camera: Atik 383L (Astronomik Gen 2 LRGB Filters) Exposure:
Exposure: 32 x 10min (1x1 bin) exposure with UV/IR block filter, 10 x
4.5 min (2x2 bin) each RGB
exposures.
Processing: Data
Collection - Sequence Generator Pro (as FITs). Subframe calibration
- Pixinsight. Subframe registration and integration (Median combine - Winsorized Sigma
Clipping) - PixInsight. Non-linear stretching, normalization and
gradient removal - PixInsight. Generation of starless nebulosity images
for later processing - starnet++. Curves, Levels, RGB combine, Luminance
layering - PixInsight. Stars and Starless combine - PixInsight. Final finishing - Photoshop. RGB calibration
- eXcalibrator. Annotation - PixInsight, Aladin (Simbad and NED), and PhotoShop. This image is a RGB combine with
Luminance layering. Images processed at 3354 x 2529 resolution. Final
Image size is approximately 3354x2529. North is up in this image. This
image shows a region of interstellar material and dust illuminated by nearby stars.
This dust also blocks the visible light from background stars and objects. The central part of this image is
LBN 10. Imbedded in this LBN structure is the dark nebula LDN 134. LDN 134 is
divided into three parts, (a, b, and c). Interestingly, there are a number of
background galaxies that are mostly pretty distant - upwards of 300 million
light years by redshift estimate. These objects
and some of the brighter stars are identified in the annotated
image. Horizontal FOV is approximately 85 arc minutes. Full size
image scale is 1.82 arcsec/pix. Image center is approximately - Equatorial 2000: RA: 15h53m39s DEC: -4°55'50"
