IC 4665 is a wonderful open star cluster in northcentral Ophiuchus. The sketch at left renders a low magnification (36X) view in the Meade 10-inch Newtonian. The cluster is centered, a collection of some 30 stars scattered across a 40' diameter area. The cluster is defined by a dozen 6.9 magnitude to 8.9 magnitude stars loosely organized in pattern reminicent of a fireworks display starburst. Perhaps, this object will one day be known as the "Starburst" cluster. Nearly 60 stars to magnitude 13 are dusted throughout the field. You'll find IC 4665 just 1.4 degrees north-northeast of 2.8 magnitude Beta (60) Ophiuchi. Under a dark sky, this beauty is visible to the naked eye.
