This Tuesday will be the last chance to view Venus in transit for the next 100+ years, so I'm planning to make the most of it. I'd also like to capture what I see for posterity, but this type of event is decidedly something new to me. I suspect that I can't simple aim at the sun and fire away. If a simple magnifying glass will kill an ant and cook a hot dog, surely my lens would concentrate the sun's rays to a disastrous effect on the lens/camera internals. Surely the shutter, sensor, etc. would be in danger of frying.
Are my suspicions correct? If so, is there anything I can do to mitigate the effect to a safer level--via a ND filter, smoked glass, etc? What other considerations do I need to make in attempting to capture such an event?
