Star Party at The Robert Ferguson Observatory

This part star party/part Night Sky Trails is a hybrid version of these two events. While our dome and west wing telescopes will remain closed, we will allow small groups in our east wing to view images from our RC20, research-grade telescope. Sky tour docents will be stationed outside to give guests laser guided tours of the constellations.

You MUST have a ticket to attend this event.  Attendance is limited and, while remaining tickets will be sold at the door, they will be subject to availability.

Cost is $10.00 per adult, $5 for students and seniors 60+, and children under 12 are FREE.  (Note: while children tickets are free, they are still required.)

(Plus State Park Parking Fee $10.00 per vehicle.)

This is primarily an outdoor event. Only part of the observatory will be open.

COVID-19 Update

Based on direction from Sonoma County, RFO is requiring guests to wear face masks at all events, regardless of their vaccination status.  And, of course, if you are not feeling well or have a fever, please stay home. Thank you!
