Chabot boasts three telescopes on its observatory deck. Nellie, Chabot‘s youngest and most powerful, is housed in a rolling roof observatory, allowing access to 180 degrees of sky. This modern, research-quality telescope offers breathtaking views of the cosmos.
The impressive 20" telescope, named Rachel, is the largest refractor in the western United States regularly open to the public. Its companion, the 8" Alvan Clark refractor, named Leah, is the original 1883 instrument donated by founder Anthony Chabot.
