RFO Night Sky Classes, Fall Season, Individual Classes
Robert Ferguson Observatory, Sugarloaf Ridge State Park
Kenwood, CA
Share this event:

Night Sky Classes are offered in three seasonal series (six classes each) and are designed for everyone from total beginners to experienced amateur observers. Persons who take all three Night Sky series (18 classes in all) will learn the entire sky seen from our northern latitude. Whether you want to learn the constellations or have a telescope and want to expand your knowledge of deep sky objects, the solar system and beyond, these classes have something for you.

Tickets may be purchased for individual classes or for the six class Fall Season.

Program information:

The presentations last approximately 90 minutes. A few constellations are introduced in each class: their myths, history and interesting stars. We also cover deep sky objects within those constellations, such as the beautiful nebulae and clusters that never cease to awe and amaze. A detailed list of topics for each class is listed below. After class (sky conditions permitting), we go outside and locate the constellations presented. Then we move to the Observatory's telescopes to view the individual objects until 10:30 pm, or later.

For more information about the Night Sky Classes, please visit  and click on the "Night Sky" tab.
