Transits of Venus across the disk of the Sun are incredibly rare, with the transit of June 5, 2012 being the last in our lifetimes. For this event, I transported my Celestron Super C8 Plus to the summit of Haleakala in Maui, Hawaii because it was one of the only sites where the entire transit would be visible and, at 10,000 feet elevation, I'd likely be above any clouds. The result was this image, which is one of only a few published images showing the entire transit. Exposure: Celestron Super C8 Plus,  Canon EOS 20D DSLR camera, 1/1000 second at ISO 800. 

This image was published in the September, 2014 issue of Sky & Telescope Magazine. and the February, 2020 issue of Astronomy magazine.
