CalStar is a regional dark-sky star party held annually in late September or early October in Monterey County, California. The event format and atmosphere are quite casual, and there are no scheduled activities, vendors, or fees other than the camping fee collected at the park entrance. At CalStar, the focus is on observing and enjoying the dark skies and good company.
