Steve,
Nice work.  Is the autofocus sensor on the 10D sensitive enough to
accurately focus through your telescope at f/6.3?  For example, can you
focus on the edge of the moon or on a bright planet?  I am interested
because I would like to use a 10D with my f/6.8 telescope for imaging
lunar eclipses and next year's Venus transit without needing a laptop to
check focus.
Thanks,
Joe
