Jupiter 1 Day Before Opposition

I was able to take some pictures of Jupiter 1 day before opposition.  There happened to be a transit of Io during my session, and I was going to create an animation, but I never got the focus quite right.  I'm thinking the objective is a little off of collimation in the refractor, as the focus varied across the field a little bit.  Since my animated frames didnt work out, I'll post the best of the frames here instead.
