North is up in this image. LBN 406 is a broad, very faint region of dust reflecting nearby star shine - also referred to as a Molecular Cloud. It is the dominant central object in this image and is sometimes given the common name of the "Laughing Skull Nebula". Its hard to see a resemblance, but the skull jaw would be to the right and the eyes are facing up. Also in the upper left is a portion of a similar cloud of dust - LBN 413. Toward the lower edge is a Saturn like object that is really a interesting distant galaxy known as UGC 10548. There are numerous other small galaxies visible in this image. Here is a link to an Annotated Image to help you locate some of the more visible ones. Horizontal FOV is 115'


Image center is approximately - Equatorial 2000: RA: 16h 46m 01.2s Dec: +6008'50"
