Helpful equipment includes a camera with fast continuous video mode and a mount that automatically tracks the Moon . The featured fleeting superposition was captured from Seoul , South Korea two weeks ago during a daytime waxing gibbous moonrise. Within 1/10th of a second, the airplane crossing was over .
