    What do I need to safely photo the sun? Is an ND16 filter enough?

    You need at least 9 full stops of light reduction to safely photograph the sun, and I think the ND16 is only providing 4 full stops. You also need to worry about blocking infra-red, which an ND filter might not do.

    I'd look for a dedicated solar filter. Reputable brands include Coronodo, Astro-Physics, Kendrik, Orion Telescopes, Thousand Oaks. And look for one intended for photography, not just visual observing.

    Also: remember that the sun is small, same visual size as the moon, so you probably want a big zoom (400mm) or a small telescope. And you need to protect the entire optical path of the telescope, or it can melt or catch fire. Take *lots* of images, since atmospheric turbulence will cause most to be blurry, and just keep the few that are sharp.

    But why would you want to take an image of the sun ?

    Is that a photo, Redridge? As in not a composite or Photoshop job? It looks like something out of a sci-fi movie. Very cool!

    If that's what you can expect shooting the sun, it seems like it would be a lot of fun to try.

    Do NOT use photographic ND filters

    No guarantee they screen out UV and IR sufficiently. Get this instead, use at least a 400-500mm lens (ideally, 1000mm). Image here taken by a 1300mm f13 mirror lens with a Panasonic G1. Also, those spectacular prominence images like the one shown require a satellite (!) or a telescope with a special filtration system using what is called an etalon which only allows a very discrete wavelength through. You can use heavy density welder's glass to view the Sun with your eyes, but it is optically poor and cannot be used on a camera lens.

    Transit of Venus across the Sun is June 5th, the last one in about 100 years!
    I'm going to shoot video of it via the E-M5 and combine frames to form final images.

    Filter: You can buy this film, there are some American sources, or a glass filter from some of the big camera sellers, look for the name, "Thousand Oaks."

    Man I wished this topic had come up earlier. I have been trying to source one of the baader filter but I cannot. I am kinda bummed out.

    Right! I should make a reference to the sunny 16 rule, must be about the sun! :wink:

    britops, I can only second the advice not to use ND filters! They will not protect your equipment adequately.
