Wish someone would invent a clear sky alarm that would wake me at night to let me know a clear sky has suddenly developed. It's so rare to get a clear sky around here that it seems a shame to miss any opportunity to do some astronomy. That's why I keep an astronomy binocular and/or a small telescope ready to go at a moment's notice, but I still need a clear sky to use them. Maybe I should stay up at night and start a clear sky astronomy service. I could give call to some of our local astronomers when there is a clear sky. There are a lot of telescopes and astronomy binoculars in the Chicago area and astronomers anxious to use them.
