Double Star Bonanza!

Checking more off my list for the Indiana Astronomical Society Novice/Urban Observing List for August 2013. I'm tagging all my posts with those objects: #novice8/13 and I need to get a total of 6 in order to get a certificate!

The only double stars I've seen before these were Mizar and Alcor in the Big Dipper. I was surprised that I could see any division between the stars at all! The stars are a little out of focus, and obviously wouldn't be that close together or that spherical-looking under higher magnification.
