    CalSky predicts that there is going to be an ISS solar transit over
    Bangalore, India (where I live) on 9th February. I am planning to attempt
    photographing this. I have some questions related to this:
       1. Since the event is two weeks from now, in what ways can the center
       line and the predicted time change over time due to change in orbit
       parameters? Or in other words I am trying to estimate when I should start
       scouting for a good location on the center line? Would 2 weeks ahead be too
       early or should I wait till it's about 2 or 3 days prior to the event?
       2. I have seen Thierry Legault's amazing pictures. But very limited
       information on how to prepare and photograph such a short event. It would
       be great if any of you can provide suggestions and tips.
       3. How frequent are transit events for a given piece of area on Earth?
    I have access to limited resources - I don't have a long focal length OTA
    but just an 80mm f/6 refractor.  I have a DSLR body and am considering
    using a long telephoto lens (with a converter). I have solar photographic
    filter. Given this, should I shoot stills at high FPS around the transit
    time or should I record a video and grab frames out of it to obtain good
    stills? My 60D can shoot 5.3 fps but I need to test for how long it can do
    without overrunning the buffer. It can also shoot a 60FPS video at 720P.
