Friday and Saturday Night, weather permitting
Chabot Observatory Deck
7:30-10:30 p.m.

Join Chabot astronomers on the Observatory Deck for free telescope viewing! Weather permitting, this is a chance to explore stars, planets and more through Chabot’s historic telescopes. Chabot’s three large historic telescopes offer a unique way to experience the awe and wonder of the Universe. Our observatory deck offers breathtaking views 1,500 feet above the Bay. Three observatory domes house the Center’s 8-inch (Leah, 1883) and 20-inch (Rachel, 1916) refracting telescopes, along with a 36-inch reflecting telescope (Nellie, 2003). 

• If the humidity is greater than 90%, Leah and Rachel will be closed to protect their lenses.
• Nellie is even more sensitive and will be closed when humidity is at or above 85%.
• The Observatories are closed when it is raining.

Check Chabot’s Current Weather Summary to learn what the current humidity is before your visit.

Humidity is subject to rapid changes in our micro-climate, so please check frequently.

Are the skies clear for viewing tonight? Viewing can be impacted by rain, clouds, humidity and other weather conditions. Conditions can be unique to Chabot because of its unique location in Joaquin Miller Park.

Before your visit:

• Check humidity on our Weather Station
• Check cloud cover using the live view webcam of the Center

Join Us at 9 a.m. the First Saturday of Every Month. Due to the popularity of the Kids Workshops, we can't guarantee a kit for every participant. We recommend arriving early.
