Twinkle, Twinkle little star

Seeing stars twinkling is a special experience, somehow we expect to see stars twinkle, and feel a bit cheated if thay don't. Of course the same twinkling heralds atmospheric trubulence which makes for lousy planetary viewing, where you image dances around like water on a stove. Tonight I just went out to have my evening peek at the stars, and they were doing the most amazing twinkling I can rememeber seeing, a real stellar jitterbug. It almost looked like a speeded up Hollywood special effect. Guess I'm not taking the scope out then.

[chortles] I get that effect all the time, Ian -- it's astigmatism ;-)
