Hi Marc!
One of the most common mistakes in lunar/solar photography is that we
forget the motion of the earth! Exposures over a certain length
(determined by the focal length used) become blurred by the earth's
rotation.
I haven't photographed a solar eclipse since 1994, and thus I've forgotten
the formula, but it is a serious matter.
Your "finished product" looks great!
Cheers!
