Details:
Of course, there are sharper, clearer images on SpaceWeather.com of ISS transits across the sun, but probably not many that used a cell phone camera to record the passage. Since the transit only lasted 0.58 seconds, I used the video mode of the cell phone camera (at 30 frames per second), and mounted the cell phone over the eyepiece of a 6-inch Dobsonian reflector (with a solar filter). Watching on the screen of the phone, I didn’t see it dart by, and thought maybe it was too small for this system to capture. On a computer monitor, though, and slowed down, it’s clearly identifiable as the ISS. The photo is a stacked image of the 16 frames from the video file that showed the passage. The viewing location and time for the transit were from www.calsky.com . Not bad for a cell phone camera.
