    Default Solar transits



    I want to see a mercury transit across the sun later this year, and maybe also some ISS transits. How can I view this? Solar eclipse glasses, solar filters?

    You are going to need a telescope with a white light filter. Even in a telescope, Mercury is about as big as a period on a page of print. Lots of fun to watch though. We saw the last Mercury & Venus transits.

    ISS solar transits are over in less than a second. Best captures with a camera hooked up to a telescope with a filter.

    Agreed Mercury is seen in a telescope WITH the proper white light filter. You can use a special glass or mylar front mounted filter, or a Herschel wedge (I have the Lunt one) that is mounted in place of the diagonal. NEVER use a solar filter that attaches to the eyepiece as they will break.
    I have done solar imaging with a 400 mm camera lens with a front mounted screw of 77mm white light filter.

    This year I want to try the Mercury transit with my Halpha Quark or Lunt LS80, probably the LS80.

    Here is the last transit I shot, Mercury is at the bottom left

    You can also just project the solar image from your eyepiece onto a sheet of white paper... I've viewed the transits of both Mercury and Venus that way. Works great with a refractor. I've also done it with a small reflector, but you might overheat the secondary mirror on some types, though.
