Our Observatory runs Open Houses several times a year, at which tens or even hundreds of people come to look through our telescopes. But in between those big events, we occasionally offer programs to smaller groups, such as Cub Scouts and Girl Scouts and elementary school classes.
This week, a family in the local area called to ask if they could visit. The weather was good, and the Moon was in a good location early in the evening, so I met them for a bit of Moon-viewing.
Each of the two children of the O- family took turns at the eyepiece. They studied craters and mountains on the terminator using their own eyes ...
(yes, yes, flash photography inside a dome at night is usually not a good idea, but it doesn't really matter when one is viewing the Moon)
... and took some pictures, too, by holding their cell phones up to the eyepiece. The large crater in the middle of the view is Theophilus, roughly 100 km across and 1 km deep.
