My pic of Green Sun (with T2i)

Hello:

I tried (you've got to be careful) taking a picture of the Sun using a heavy welding glass filter, an APO lens set at 300mm (when zoomed in), and the T2i at ISO 100, with a 1/4000th second exposure.

It was only on a tripod though. And wondered why I haven't recorded any sunspot or spicules or granules?

This though is my first good digital attempt. One time I had some success using the same kind filter using film at 25 ISO speed and a K1000.

What do you all think?

Maybe the focus is still a little soft. You need to have good focus to capture any sunspots.

A unique method though!

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
