Tonight (May 5th), the moon will be closer to the Earth than any on other day in 2012, and consequently we will observe what is called a "super moon". The moon will rise at 7:59pm and reach perigee (the part of its path closest to the Earth) by 8:35pm, which is when it will reach its largest size. The reason that the moon will appear so large today can be attributed to variations in its orbital path.
We recommend that you take the majority or your shots during moonrise, while the moon is fairly low on the horizon, so you can catch some interesting things - such as trees, clouds, or buildings - in the foreground.

In order to get the best moon photos, it's desirable to have a telephoto lens, such as a 300mm or longer. The key is to use a sharp lens as well as a fast shutter speed; remember, the moon is constantly moving, and you will need to use a shutter speed of at least 1/100s to freeze the moon's motion (depending on focal length and position of the moon, you may way to go higher). Avoid cranking up the ISO too much in order to preserve detail, and aim to shoot between F8 and F16. If you open up or stop down your lens too much, you will notice a degradation in image quality.
