Learn about your binoculars, and how to maintain them! This 2.5 hour workshop will guide you through the basics of optics as well as the repair and maintenance of binoculars. Bring your own binoculars to tinker with, or if you don’t have any binoculars (or any that you want to tinker with), you can help us fix some CCNH loaner binoculars that need to be repaired!

If you have small jewelers or eyeglasses screwdrivers (Phillips and flathead), please bring them. If not, we'll have some to share.

Our instructor will be Edgar Lehmann, a former optical technician and teacher. He's used his skills to lead binocular fix-it workshops, as well as repairing many optical devices for Audubon Canyon Ranch, the Marine Mammal Center, and the Golden Gate Audubon Society.

This event is limited to 15 people.
