    Capturing an eclipse

    With the solar eclipse on May 20 and the transit of Venus across the sun on June 5, I was wondering if anyone had any tips on how to safely capture these events without damaging an eye or a DSLR. Thanks.

    ND filters are probably going to be the best suggestion, but i'll leave it up to others to say which values are the best.

    To avoid damaging your eyes, use live-view, but then you'll cook your sensor instead.
    With a canon EF mount lens on live-view, the camera will automatically stop-down the lens on live-view if there's too much light coming in (assuming the narrowest aperture is small enough). But with a manual lens via adapter you can set the aperture to smallest anyway, and if that's small enough then you can use it on live-view or viewfinder just the same.

    And for the hell of it, here's a shot I took last eclipse, January 2011, 7D, EF-s 15-85, 85mm, f/20, 1/4000s, iso100:

    I didn't have it at the time, but next time I would take this shot with my ND400 (9 stops), which would go down to f/5.6 (4 stops) and bring the shutter down to 1/125 (5 stops) (if my maths is correct).
    An awful lot of electrons were terribly inconvenienced in the making of this post.
