Breyo Observatory

Siena students and faculty can study the heavens in the College’s Breyo Observatory, which boasts the largest telescope in New York’s Capital Region.

New 0.7-m Telescope on the roof of Roger Bacon

The main telescope, which features a 27.5-inch diameter mirror, sits atop Roger Bacon Hall. The rooftop viewing platform also has permanent mounts for five smaller telescopes.   

The observatory was funded by a grant from the Sherman Fairchild Foundation and a generous gift from John J. Breyo ’68 H’02 and his wife, Marilyn Breyo; the observatory was named in their honor. The observatory opened for use in September 2018, and was formally dedicated on November 10. 

Ongoing appeal for those on and off campus

In addition to the research and study conducted by the College’s science faculty and student majors, regular public observing events will be held throughout the year to welcome guests who have a fascination with space.
