Sky & Telescope Magazine is a great way for you to keep up with current events in Astronomy, and to generally stay plugged in to the astronomical community. They are making a special subscription offer for students, $27.00 for 12 issues. This is 25% off the regular subscription price. The newstand price is $3.95 an issue.
If five students sign up, then they will send us a free poster. Our choice of "a stunning, full-color Aurora poster, complete with diagrams and text, or a compilation of all 109 Messier Objects, with background information and reference tables." If ten students sign up, we get both posters, each of which otherwise sells for $9.95. We'll raffle them off in class to the subscribers.
I'll bring the subscription forms to the first couple of classes.
