William Miller Sperry Observatory, Astronomical observatory at Union County College in Cranford, United States
The Sperry Observatory houses two substantial telescopes: a 10-inch refractor in the East Dome and a 24-inch Cassegrain reflector in the West Dome.
The facility opened in 1967 through a $150,000 donation from Carrie Regina Beinecke and William Sperry Beinecke to honor William Miller Sperry.
Amateur Astronomers Incorporated operates weekly public viewing sessions, fostering community engagement with astronomical observation and scientific education.
The observatory welcomes visitors every Friday night throughout the year, with youth group sessions starting at 7:00 PM and general public talks at 8:30 PM.
Both telescopes rest on an 8-foot concrete pier supported by 30-foot deep piles that minimize vibrations during astronomical observations.
