Exposure: Exposure: 15 x 10 min  (1x1 bin) exposure with UV/IR block,  8 x 4 min (2x2 bin) RGB exposures.

Processing: Data Collection -  Artemis Capture (as FITs).  Calibrated, stacked (Kappa Sigma Combine) Deep Sky Stacker, LRGB channel registration, equalization, and central gradient removal - Astroart.  Curves, Levels, LRGB combine and finishing  - Photoshop. This image is a  LRGB combine with Luminance layering.  Color saturation in LAB color;    Final Image size is approximately 2400 x 1800.

North is to the right in this image. This field is the LBN 19 Region in the constellation of Serpens. LBN 19 is  a nebula in Lynd's catalog of nebulae - it is one of the dimmest class in the catalog. The nebula structure is 2.42square degrees in the sky and extends a bit beyond the field if this image. Within the field are other objects in Lynd's catalog; two from the LBN (LBN 11 and LBN 15); and three from the Dark Nebula catalog (LDN  169, LDN 183, and LDN 184). There are also several distant background galaxies with redshift derived distances up to 780 million light years  (they are quite small with this image scale). The two bright blue stars are HD 141851 and HD 142197. See the annotated image for identification of these features.  The bright stars  HD 141851 and HD 142197 are a relatively close 159 light years and 172 light years respectively.  Horizontal FOV is 120'

Image center is approximately - Equatorial 2000: RA: 15h 52m 58.0s Dec: -0316'57"
