LBN 406, also known as the Laughing Skull Nebula is a vast interstellar molecular cloud region in the constellation Draco. One of the few broadband targets of the galaxy seasons besides…galaxies!
The companion LBN 413 is visible on the bottom right corner of the frame.
The target is very faint and it took several hours of integration to achieve a decent SNR. The image is the result of 17hours integration in LRGB (10hrs L 3.5hrs R/G/B each).
