Partial Eclipse Report from Ethan Dicks at the South Pole: For the photographically curious, I used an Olympus E-10 with a 1.4X tele-magnifier, giving an equivalent focal length of 200mm. I made a double-layer mylar filter, which stopped down the light enough for me to shoot at 1/640 (fastest shutter speed available) and between f/5.6 and f/8. I used a variety of tools to massage the images, primarily The GIMP and the PNM Tools (plus some Perl I threw together to automate some cutting and aligning). Between the lens size and the cameral resolution, the native size of the sun is only 124 pixels across or so. I just cropped the raw frames and worked with them at camera-resolution. It would have been nice to have a longer lens than 200mm, but my digital SLR is old enough that the lens is fixed (and only 135mm-equivalent, before adding the extender). Oh... geographically speaking, I happened to be about 1000m grid West (towards N and S America) of the actual South Pole for those shots, most of which were taken from one of our science buildings, MAPO, or the Martin A. Pomerantz Observatory. The only experiment running in there this year is AMANDA, the Antarctic Muon And Neutrino Detector Array, once a stand-alone neutrino telescope, now part of the cubic-kilometer IceCube telescope (which we just brought to 50% of completion two weeks ago).
