Indiana Astronomical Society Novice/Urban Observing List – September 2013

Philip Dimpelfeld from the Indiana Astronomical Society creates a Novice/Urban Observing List each month for newbies like myself with not-so-dark skies and not-so-powerful equipment. The September 2013 list looks like fun, and I've never even heard of some of the items - so it's a great way to learn in the process.
