Armfield Observatory - A Dome

Armfield Observatory - Ed Halbach TelescopeThe Armfield Observatory is named for Luverne Armfield, the founder of the Milwaukee Astronomical Society who was involved in the early construction of the observatory and an active observer of variable stars and meteors. In fact, he was one of the earliest variable star observers as his AAVSO observer code was "A".

This observatory was built in 1937-38 with a 14 foot dome and houses the Edward A. Halbach reflector, named for Ed Halbach who served as MAS President, Treasurer, and finally as the observatory director for 35 years. He was an active observer for over 70 years.

This scope is a 12.5 inch, f/9, Newtonian reflector.  It is usually referred to as the "A" Scope. It sits on a massive German equatorial mount with a clock drive. RA and DEC are positioned using very large vernier setting circles. A limited fine slew capability (paddle controller) is provided for both axes. A 50mm finder is mounted piggy back.
