Jan. 28, 2012 – Cronyn Observatory Open House

Cold weather and clouds blowing in from the west greeted visitors. Graduate student Emily McCullough directed the 25.4cm refractor in the dome towards the two-day-prior-to first quarter crescent Moon, which made a splendid view in the 32mm Erfle eyepiece. 

Since weather prospects were doubtful, Bob Duff brought a group of visitors upstairs into the dome immediately to view the Moon. Bob also set up the Centres 25.4cm Dobsonian on the Observatory roof patio and showed visitors Jupiter, using the 12.5mm Orthoscopic eyepiece at 91X. Emily took over the 25.4 cm refractor for a while and then went downstairs to give her digital slide presentation, Telescopes. More visitors arrived and Bob supervised people viewing the Moon through the refractor and Jupiter through the 25.4cm Dobsonian. Besides Jupiter, Bob also showed a few visitors the Moon, the Orion Nebula (M42) and Betelgeuse using the Dobsonian and a 17mm Nagler eyepiece. The estimated 55 visitors were gone by 9:00 p.m. after a very successful evening of astronomy.
