This is the 24″ Ritchey-Cretien reflector as it was installed at the Star Hill astronomy retreat at Sapello, NM. The retreat was founded and operated by Phil Mahon until June 30, 2008. The telescope was previously owned by the University of Denver, and when the University needed to upgrade to two larger telescopes it was purchased by a neighbor of Star Hill. The telescope and dome were disassembled, moved down to Sapello and reassembled as you see it here. Following the closure of Star Hill, the telescope was moved back to England, where it was originally manufactured.
