It must have been "new equipment day" — I received a new Stellarvue SVR80ED refractor this morning and was surprised to have clear skies here in Northfield at sunset (how often does a new scope arrive with clear skies?). Got polar aligned and looked at the Pleiades for 2 minutes, then Mars for 2 minutes, and then the fog rolled in; I could barely see across the street, but the resulting frost looks nice.
Glad to hear you had at least a few hours of good conditions at Eagle Bluff.
