The Best Camera Gear for Moon Photography:
Tripod - A secure base and workstation for your camera is essential to capturing the moon and avoiding camera shake.
Long zoom lens - In order to help fill the frame and properly show off the moon, the longer your zoom lens the better.
Shutter release cable - Or a wireless remote. It's nice to have and helps avoid camera shake. If you don't have one you can cheat and use the self-timer function on your camera.
ISO - Should be set to 100 or lower to eliminate noise and grain.
Aperture - Because you're after crisp, clean shots, shooting at f/11 to f/16, depending on your lens, will be the best place to start. Research your lens' sweet spot to find the sharpest aperture.
Shutter speed - Starting at about 1/60th to 1/125th should be a great starting point.
What is the Looney 11 Rule?
In moon photography, there is a “rule of thumb” that is easy to memorize and should get you close to a good exposure of the face of the moon – the “looney 11 rule.”
The Rule - Set aperture to f/11 and shutter speed to the reciprocal of the film speed.
For example - f/11 at ISO 100 and 1/100th second shutter speed.
Another example - f/11 at ISO 200 and 1/200 second shutter speed.
