While in San Diego I took the opportunity to visit California’s largest State Park, the Anza-Borrego Desert State Park. The park is located between San Diego and Joshua Tree National Park in Southern California. That evening I waited for the Moon to set and aimed my telescope at Comet Hartley. A few days earlier the comet passed by the Double Cluster in Perseus. In this image the comet is surrounded by open clusters.
