Mu Scorpii

Before heading off to bed, I spotted what appeared to be a comet-like image in the lower southwestern portion of the sky; the southern end of the constellation Scorpius. Having lived in the Northwest and at sea-level for most of my life, I've never had the opportunity to view this portion of the sky. Looking through the telescope it became evident that this image was comprised of an open cluster, and some binary stars.

The photo above is comprised of 5 one-minute frames for Mu1 and Mu2 Scorpii, an eclipsing binary. Mu1 is considered a variable star due to the impact of the eclipsing behavior on its apparent magnitude. May be a little over-exposed.
