My tripod was a short one just big enough to hold the camera up. An SLiK Mini Pro all of about 8" tall. If you don't have a tripod take something to set it on like a small bucket and something to put under it to adjust the angle maybe pieces of cardboard. If you hold it they will all be blurry just like the year I tried to take some fireworks pics from a boat.
One other thing I almost forgot. I used a remote trigger release. If you don't have one you can hold a small piece of cardboard in front of the lens, push the shutter release, wait a second to make sure the camera has stopped moving, remove the cardboard for "x" seconds, put the cardboard back and push the shutter release again to close it. Thus removing any shake when you touch the camera.
If you can't figure out how to make the shutter stay open, pic a long shutter setting like 20 or 30 seconds and use the cardboard trick above to control the time. If you do this you won't be able to close the shutter by pressing the release, just cover the lens till it closes on its own.
