This is not that hard to do. If you would search the internet, there are quite a few good sets of intructions out there. To start out with one.
Have fun shooting.
Agree with above & will add a steady camera is needed. You will either need a good tripod or something solid to rest the camera on, and it must not move while the shutter is open.
