Oops - Sorry about that Clackers. I clicked on the thread and think I jumped in at a point earlier on - quite a few posts had been made that I didn't see. Didn't mean to add to those.

I know you can get hit over the head too many times and then start to see stars:)

??The moon moves almost the same rate as the stars??

Chances are that with the teleconverter, your exposures ran a bit too long and at the magnification you showed, moved significantly while the exposure was being taken. A teleconverter multiplies the f value of your lens by the same amount making the effective f-stop fairly high. Your camera would compensate by extending the shutter time. This is particularly bad during totality since the moon is only a fraction of the brightness it is without the eclipse.

The remedy is to use a higher ISO to get shutter speeds down, and if that isn't possible, a tracking drive to follow the moon's movement.
