Sky Maps

http://skymaps.com/

This is a great place to go for free monthly star charts. This will give you really good, but approximate skyviews for nearly all uses. We will see later how to generate custom sky charts.

to find out times for sunrise, sunset, moonrise, moonset - customized for your city.

For next class, investigate the celestial sphere. Bring a decent image or two.
