About this object
About 3 degrees east of the famous Soul Nebula and right on the border between Cassiopeia and Camelopardalis lies a rather long area of dark molecular clouds within a larger area of background HII emission. A good portion of these molecular clouds are part of Lynds Catalog of Dark Nebulae which is a list assembled by Beverly Lynds in the 1950s-1960s. These dense molecular clouds are often areas of star formation and indeed there are at least two easily visible young stellar objects (YSO) within the image and nine LDN objects (1378-1386). The annotated image circles these LDN objects along with a few background galaxies and the YSO's. This area also has a large area of HII emission and some brighter un-catalogued emission nebula and is part of the larger Sharpless 2-202 area. Just left of center is the large (29 arc minute) Stock 23 open star cluster which lies 1200 light years distant. This star cluster seems to reside in a faint bluish haze and some wisps of reflection nebulosity are visible in the full res view.
