LBN 36 and LBN 37 in Serpens



Scope: Explore Scientific MN152 Maksutov Newtonian at f/4.8, Location: DAA Observatory, Shelter Valley, CA,  29 May 2019  Camera: ST8300M (Baader LRGB filters)

Exposure: Exposure:  15 x 15 min (1x1 bin) exposure with IR/UV Block filter, 8 x 4.5 min (2x2 bin) RGB exposures.

Processing: Data Collection -  Sequence Generator Pro (as FITs).  Exposure calibration, LRGB registration, and stacking (Median combine -  Winsorized Sigma Clipping) - PixInsight.  LRGB channel registration, equalization and gradient removal - PixInsight.  Curves, Levels, RGB combine, Luminance layering - 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  2800x2100.

North is up in this image. The dominant (roughly center) object is LBN 37  - also known as Sharpless 2-33 (and MBM 38, molecular cloud roughly occupying the same area). Distance estimate for LBN 37 / Sharpless 2-33A is approximately 358 light years.  A larger, dimmer LBN 36 is to the left. A single galaxy with redshift distance estimate (CGCG 023-004, also known as PGC 56472) is near the right edge. Also there are many background galaxies in this image field. These objects and some of the brighter stars are shown in the annotated image.   Horizontal FOV is about 85'. Image resolution on the full size image is about 1.82 arcsec/pix. 

Image center is approximately - Equatorial 2000: RA: 15h 59m 57s Dec: -0128'39"
