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: -455'50"
