Stargate features a 12.5-inch f/17 club-built Cassegrain telescope under
a steel dome. The club also owns a 22" Dob, plus many loaner scopes for
members to use. The observatory is open to all club members in accordance
to the
Stargate Observatory Rules published in
the member handbook. Those wishing to use the observatory must call the 2nd
VP by 7:00 pm on the evening of the session.
The telescope at Stargate Observatory was originally
designed as an f/4 Newtonian and debuted during 1966 under a dome on the
roof of Warren's Lincoln High. The telescope was refigured as an f/17 Classical
Cassegrain and was moved to Stargate Observatory during the spring of 1970.
The telescope underwent a major refurbishment during 1992-4, and reopened as a
dual-purpose telescope, easily convertible between its f/17 Classical Cassegrain
design and its f/4 Newtonian design.
