    Hi all,
    Did an experiment yesterday with my Canon EOS 450D hooked up to the laptop and 
    some software that taps the live-view signal of the camera display. This makes 
    it possible to use the camera as a film camera.
    I was surprised by how well it works. Bright stars are visible, and bright 
    As a test, I filmed Lacrosse 5 (05-016A) moving near Pollux last evening. A 
    YouTube version can be seen here:
    Image is about 5 degrees wide horizontally. Lens was the EF 50/2.5 and live view 
    zoomed 5x (the field becomes maller then, but stars better visible).
    As I can't get a time signal into the images and the number of visible stars is 
    low, it is for fun purposes only. The EF 100 lens goes deeper (~ mag 4) but the 
    FOV is very small then (2.5 degrees).
    Sometime soon I'll do further experiments, with the camera hooked up to the 
    ETX-70 telescope. It might be usefull to capture ISS solar/lunar transits.
    The software used is here and will work with all EOS with live-view capability:
