An Airplane in Front of the Moon

If you look closely at the Moon, you might see an airplane in front of it. Capturing an image like this requires precise timing, a fast exposure to freeze the plane without overexposing the Moon, and a steady camera. It also takes luck, as not every plane crossing the Moon's path will be perfectly aligned. Equipment like a camera with fast continuous video and a moon-tracking mount can help.
