Hey Trevor, I was wondering if you ever have trouble keeping Jupiter on your chip because of the periodic error of your mount. The field of view on my chip becomes less than 4 arcminutes when I'm imaging at F/30. Jupiter itself is almost 1 arcminute so with my imperfectly driven alt-az mount Jupiter often drifts off my chip. At that moment I have to cut my AVI file short because Registax can't handle the abrupt change that would result if I tried to splice two disjointed AVI segments together.
