Observatory Night lectures will take place on the third Thursday of the month from September through December. These public talks feature a variety of astronomical topics that are timely and of general interest. As always, rooftop viewing will follow the talks when weather permits.
We are trying a new format this season. Doors open at 7:00 pm. At 7:15 we will offer a short presentation on something of practical use, like astrophotography tips or stargazing with your smart phone. The main presentation will begin at 7:30, as usual.
