10/3/14 The Moon in Chabot's 8" Clark Refractor
« on: October 07, 2014, 11:58:44 AM »
Last Friday night the skies were dry and especially steady over Chabot Space and Science Center in the Oakland hills. As a volunteer operator of Leah, the 8" Clark refractor, I arrived early and started viewing the Moon right around sunset. The terminator was just west of Copernicus and with seeing about 4/5 the view was spectacular. Over the course of the evening we counted 277 members of the public viewing through the scope. Magnification was kept at 72x for most of the night, as people getting their first view through a scope seem to enjoy a low-power view of the entire Moon more than a high power view of particular features.

Once the public session concluded around 10:30pm, I bumped up the power to 200x. The Moon was lower now and seeing only about 2.5/5, but a few volunteers who hung around late still enjoyed a great view of the lunar domes west of Copernicus (Rukl chart #30). Crater pits were noted atop several of the soft looking, gently rounded domes.
