One step forward, ten back...

As soon as I finished he last photo, we were hit with a week of clouds. Now that they have passed, somehow I have picked up a periodic tracking error. 30 second shots are still possible, but roughly half the subs shot are trash. And what is odder, the problem that was causing this before does not seem to be to blame-so that is why there have been no new pictures this week; I'm playing Master Detective/Junior Machinist instead. All part of the game, though.
