You have to remember somethings though. 1. They dont take long to happen , less than a second. 2. You need a large satellite. I would choose ISS as best current target. Or check out the size. 3. satellite silhouette's less than your confusion disk caused by local "seeing" are rather low contrast. 4. Irradiation causes small black dots seen against a bright background to disappear. If the angular size is less than the diffraction disk you wont see it. 5. Since you need to be sure of it crossing the disk, you need elements to be current as possible.
