Hi: I've go the sun spot picture now.
I'm using a different lens now. A Kenko (420mm F8.3 - 800mm F16)
lens from 35mm on my T2i with the welding filter in front (dangerous though
because I'm hand holding it) and the T2i is 100 ISO at 1/4000 sec.
But now I've got Sun spots and it even, when I checked, confirms with a
professional pic of the Sun posted on the net:
