Observatory Public Exploration Nights (OPEN) are your portal to the Universe! Join us at the Rancho Mirage Observatory to glimpse beyond our world through our PlaneWave Instruments CDK 700 telescope. Ask questions and learn fun facts from astronomers and volunteer docents as you take in 100-350x magnified views of planets, nebulae, star clusters, and more (weather permitting).

No registration is necessary for this drop-in, open-house-style event. Due to the capacity limits of the Observatory, you may experience a short wait, but everyone will have a chance to get in.

Please check back soon for more updates – or you can join our email list here to find out the latest updates.
