Hello All,
I headed to Missouri yesterday to watch the Total Eclipse, and wanted to take some photographs. I needed to protect my lens and camara from the intense sunlight.
I built my "DEFCON 5 Lens Defender" out of Baader Solar Film and cardstock, modeled in 3D software. It slides over the front of the lens, and was sized so that it would not fall off my 200mm lens. The Baader Film allowed 1/100,000 of the sunlight through the lens, and reflected IR and UV rays. The film is a bit "wavey", which did not affect the photos. Stretching the film causes a significant loss of solar protection, as it reduces the density of the film. Overall, the device worked better than I expected.
I hope those of you in the US were able to get a glimpse of the eclipse.
