Sheep Hill Observatory is an Astronomical observatory located in Morris County, New Jersey. It features an 18 inch (457mm) Newtonian reflecting telescope and is open to the public on the 3rd Friday evening of each month, weather permitting. It is also made available to Schools, Scouting Groups and other educational groups upon request. ==History== The Sheep Hill Astronomical Association began in the mid 1960s as the Booth Astronomical Association, named after Les Booth, a former Boonton High School principal who taught night classes on astronomy. After he retired, his former students got together with him and formed the organization with the goal of building an observatory.〔''The Star Ledger'' March 8, 1992 Mark DiIonno ''Visionary Group Runs Observatory''〕 Sheep Hill, in Boonton New Jersey was the chosen location. The group secured donations of materials, labor and money including the skills of 2 master masons from Boonton, Edmund De Dominicus and Leonard Creatura, who constructed the building. The 16 foot diameter steel dome was set on the building by crane and the observatory was completed in 1973. The original instrument was a 16 inch Newtonian reflector and custom equatorial mount, all built by the club members. In August 2001 the main telescope was replaced with an 18" reflector.
