Sun through the trees

I know its dangerous to take these sort of shots, a powerful lens focusing down on an object burning at 5,505 °C outputting 38,460,000,000,000,000,000,000,000 Watts of energy onto a part of the eye a few mm across, I mean, what could possibly go wrong?

After trying a variety of shutter settings this seems to be about the best of the bunch. so I've gone with it.
