This is the kind of sky that makes astronomers smile. Clear and painted with twilight colours.

This was the scene two weekends ago, on August 26, at the annual Starfest star party in southern Ontario. Starfest is Canada’s biggest annual astronomy gathering and this year attracted about 700 people, filling the campground with tents, trailers and telescopes.

I was fortunate enough to be able attend this year, as one of the guest speakers in a pretty full program of afternoon and evening talks. I presented two talks, on the “Great Southern Sky” and on “Ten Tips for Better Pix,” plus presented a laser tour of “my sky” after dark on the Friday.

Starfest, as with other star parties I’ve been to lately, hasn’t fared well for weather in the last few years, but this year the clouds (mostly!) stayed away and people enjoyed a fabulous weekend under the Milky Way and summer stars.

This is a roughly 180° panorama taken at twilight, showing the rising dark blue arc of Earth’s shadow at left, with a strangely bright glow in the atmosphere above it. At right is the glow of sunset and some crepuscular rays (shadows from distant clouds) visible as bright and dark bands across the sky.

Starfest is a great star party. Anyone in eastern Canada interested in astronomy should make a point of attending. Next year’s event is August 16-19, 2012.
