This is the moon, as seen in a two-minute exposure. One doesn't often think about how bright the moon really is, but consider this: The bright part of the moon is directly lit by the sun, and that is being reflected down to earth. What that means is that we're essentially getting the illumination of the ground during a bright summer day sent to us from the moon. Consequently, while one has to have a shutter speed of several seconds when photographing stars, if you want to photograph the moon and see any details, you should set the shutter to 1/80th of a second.
