M62 - Globular Star Cluster

Messier 62 is located in the southern constellation of Ophiuchus. It was discovered by Charles Messier in 1771. It lies at a distance of about 22,000 light years from earth and has a diameter is 110 light years. Its estimated mass is one million solar masses and it contains over 200 variable stars. In 2013, astronomers discovered a stellar-mass black hole in M62, one of the first to ever be found in a globular cluster.

Celestron EdgeHD11 f/10 and ASI2600mm camera
20x30sec RGB subs and 33x30sec Lum


With a Declination of -30 degrees, this was a difficult object for me to capture as it never gets more than 25 degrees above the southern horizon and I have very limited view in that direction to boot. I wanted to capture at least 40-60 luminance subs, but with the limited view and not very ideal weather conditions I settled for only 33 good ones to go with the 20 RGB subs.

This one deserves much better treatment (and longer integration time) but it is on my list for the M110 award at TSS and I don't want to wait another year to complete that contest.
