The Seestar S50 started this image at 10:00PM to 3:50 AM. During this time 976 ten-seconds subframes were taken. Of those 865 passed muster. The images were pieced together as a mosaic. Image right annotates some points of interest.
LdN refers to Lynds Catalog of Dark Nebulae. What is a dark nebula? (Wikipedia: A dark nebula or absorption nebula is a type of interstellar cloud, particularly molecular clouds, that is so dense that it obscures the visible wavelengths of light from objects behind it, such as background stars and emission or reflection nebulae. The extinction of the light is caused by interstellar dust grains in the coldest, densest parts of molecular clouds.)
