Collection - CCDSoft (as FITs). Calibrated, stacked (Sigma Kappa
Combine) in Deep Sky Stacker, L - RGB channel registration, equalization, central gradient removal -

Final color Calibration with eXcalibrator. This image is UV/IR Block for the Luminance channel and then a LRGB
combine with Luminance layering. Final Image size is
approximately 3352x2532 resized to 3200x2400. 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: +60°08'50"
