Strawbridge Observatory

The Strawbridge Observatory at Haverford College houses 12-inch and 16-inch Schmidt-Cassegrain telescopes which are actively used by students in Haverford astronomy classes. The telescopes are also periodically made available for public use with teaching assistants and/or professors present to provide assistance and background information about what is being viewed. Note that the telescopes are only used when it is clear, and the domes are not opened when it is cloudy.

If the weather is in doubt, your best option is to email Mariah Baker ( or Beth Willman ( ask whether observing will take place. Alternatively, you can email us at with questions or requests for information. For last minute weather updates for events, please call 484-727-8766 (484-7ASTRON)
