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?
David
