Look at stars, galaxies, nebulae and star clusters with the help of NSA member telescopes. Observing highlights will include the Pinwheel, Whirlpool, Andromeda and other galaxies; The Hercules Cluster, The Double Cluster, The Pleiades and other star clusters; Lagoon, Trifid, Pacman and other nebula, and the planets Mars, Neptune and Uranus if conditions are good.

Dress for chilly evenings and bring a flashlight covered with red plastic or cellophane (red light preserves your night vision).
