Zoom Lens
The moon is thousands of kilometers away. Your camera isn't going to be able to capture it properly without some sort of help. You can give it that help with a zoom lens. It's a good idea to look for anything higher than 200mm. If you don't have a zoom lens, the alternative is to use shorter lenses with the integration of foreground elements to make the shot clearer.
Use a Secure Base
The first thing you should think about setting up is a secure base. Find a steady tripod stand to mount your camera. You need a stable base to avoid any form of camera shake. You'll be zoomed in quite a bit, and even a minor shake in your camera will completely ruin your shots.
Shutter Release Cable
A tripod does reduce most of the camera shake, but there will still be some shake from when you click the button to take the shot. You can either use a shutter release cable or get a wireless remote. If you don't have either, you could just use the timer on your camera.
