Shelter #2 parking lot
Look at stars, galaxies, nebulae and star clusters with the help of NSA member telescopes. Observing highlights will include: Open Cluster, Globular Cluster, Double & Coloured Stars; Jupiter sets around 11 p.m. and Saturn is at its brightest. Three planets Jupiter, Venus, and Mercury meet in the western sky coming within five degrees of eachother, a unique event. Dress for a chilly evening and bring a flashlight covered with red plastic or cellophane (red light preserves your night vision). Please arrive around 7 p.m. or come early and hike the trails. You are welcome to bring your own telescope or binoculars. In the event of inclement weather the event will be canceled.
