A first shot of the Venus Transit of the Sun…
That little dot is Venus crossing over the front of the sun.
Taken with a 400 mm lens, using a eclipse sunglasses filter, taped onto a UV filter…
Tech Specs: Canon 5D Mark III, 70-200mm lens w/ 2x extender, taken on manual mode: 1/400 second exposure, f/8, ISO 8,000 on a tripod.
I took apart a set of eclipse glasses, and taped the film to a 77mm UV filter with gaffer tape. It didn’t cover the entire lens, so I shot at f/8.
