We put a solar filter on one of our CPC1100 scopes (11" aperture, f/10 SCT), and attached a Canon EOS 60Da DSLR camera at the Schmidt-Cassegrain focus. The camera was set to capture 1280x720 video at 59.94 fps. Unfortunately I forgot to sync the camera to the PC, so the timestamps were off, but successive frames are about 1/60 seconds apart. (In the composite image shown above I actually have superimposed every second frame, i.e. images that are 1/30 seconds apart.)
We were a bit late setting things up and I was still fumbling around when the event happened. In fact, I didn't see anything at that time on the laptop screen (the camera was connected and controlled from a laptop) and was disappointed. However after getting back indoors and while replaying the movie ... voila ... there was the ISS!!! We caught it ....
Note:Astronomical images are typically not bright and therefore require your monitor to be properly calibrated. While a proper calibration of the monitor is time consuming (and expensive), a quick (and dirty) way is to adjust your monitor so that you can see ALL the 17 different shades in the image below, in particular the darkest shades.
