DG 113 (LBN 1022 and others) is a reflection nebula illuminated by BD-07 1642 (HIP 33420 and others) a magnitude 6.3 V star in Monoceros. This object is located approximately a degree from M50. The Dorschner and Gurtler Catalog was developed through an investigation of reflection nebulae on the Palomar Sky Survey. The only source I could find is this table - http://www.docdb.net/history/texts/display.php?article=1963an____287__257d.

 

Luminance – 24x600s – 240 minutes – binned 1x1

RGB – 8x300s – 40 minutes each – binned 2x2

 

360 minutes total exposure – 6 hours

 

Imaged over six nights in November and December, 2019 from Dark Sky New Mexico at Rancho Hidalgo (Animas, New Mexico) with a SBIG STF-8300M on an Astro-Tech AT12RCT at f/8 2432mm.
