ETS is a fun and exciting collaboration between amateur astronomers from across Southern California and the Forest Service, with support from Palomar Observatory.
One night a month from spring through fall of each year, Observatory Campground on Palomar Mt. becomes a true dark site, and, after a talk on an astronomy-related topic, campers from all over the mountain and other visitors have a chance to see some of the sights of the night sky through the telescopes of the ETS volunteers.
For the volunteers, the evening starts with a potluck dinner and socializing around 6:00, then the talk usually starts in the amphitheater at 7:00 or 7:30, and is followed by the viewing session.
After the visitors leave, the volunteers generally spend the rest of the night having their own star party under the same sky that made Palomar Observatory so successful.
