Saturday's Observatory open night went very well. We had 29 visitors, all ages represented, with a good number of them College students. The last little group, two college couples, arrived just before 11 PM closing. Most visitors got to see the Sagittarius Cluster (M22) which is a beautiful globular star cluster of about 70,000 stars, the Moon, and the Andromeda Galaxy. The Moon is always a big hit — something we see very often but not with the kind of detail we see through a good, big refracting telescope. At one point in the evening I think we had around 22 people in the dome — a 16-foot diameter room — which may be some sort of record for us! The air was cool, the sky was perfectly clear (for Northeastern Ohio) and the atmosphere fairly steady. Got home just before 1:00 AM. In all, a nice night.
