While I appreciate the intent behind this, the only way to learn the night sky is to get out under it and look up. A session here or there really is not going to help. Imagine one of your music students that you only see 2-3 times a year because their schedule doesn't allow them to practice the instrument more often. Just how quickly do you think they would learn to master the instrument? Learning the night sky is very much like learning to play an instrument. While a bit of guidance will help keep the student on the proper track, it only practicing regularly that results in the student learning to play the instrument. My recommendation for learning the sky - get a Planisphere (either an app or a real one) and spend evenings looking at the sky and learning the lay of the land (so to speak). You don't even need a telescope for that. Tim
