LBN 654 and LBN 561



Scope: Explore Scientific MN152 (Mak-Newt) at f/4.8, Location: DAA Observatory, Shelter Valley CA,  10 September 2018  Camera: ST8300M (Baader LRGB filters)

Exposure: Exposure:  16 x 15 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 - 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.  Morphology transform - PixInsight. Images processed at 3352 x 2532 resolution. Final Image size is approximately  2600 x 1950.

North is up in this image.  This field straddles the border between Cassiopeia and Andromeda. The long diagonal swath of nebulosity is LBN 564; the smaller patch to the right and roughly perpendicular is LBN 561. These nebulae are interstellar material reflecting starlight (and blocking optical visibility behind them).  LBN 564 has some molecular clouds  within its overall structure. Three of these clouds are from the massive collaboration of the Planck Catalogue of Galactic Cold Clumps (PGCC). There are some background galaxies in this field. The more significant ones range from 179 to 593 million light years distant.  These nebulae, molecular clouds, galaxies and some of the brighter stars are identified in the annotated image..   Vertical FOV is approximately 85 arc minutes. image scale (large image) is 1.96 arcsec/pixel

Image center is located approximately - Equatorial 2000: RA: 00h 00m 14s Dec: +4826'26"
