I predict a clear night, no moon, no wind, no humidity, no clouds, the mount will track, PHD will work flawlessly and the camera will not ice or even have a hint of dew, the battery will not run out and Eta Carina will blow up just as I start shooting a series of 5min exp at F10 centered on the keyhole.
.... Oh and the following day I wake up hearing on the radio that I won lotto.
