Object name: IC4996

Designation(s): IC4996,

IC 4996 is a small tight open cluster in Cygnus about 5600 light years away. WEBDA puts its age at only 9 million years. So young, a couple of its stars haven't yet reached the main sequence so it is studied to learn more about rather rare pre-main sequence (PMS) stars. I didn't take time to look into those papers. The cluster was discovered by William Herschel on September 20, 1786. It isn't in either of the Herschel 400 observing programs.

I left no notes as to why I put this one on my to-do list. It may have been a mistake as I only took 2 frames of each color and one very poor luminance frame I didn't use. This is a pure RGB image with only those 6 RGB frames.
