Point your camera at the North Star. It appears
to stand still while all the others rotate around
it.
Use a VERY long exposure, at least an hour and up to
six hours at f16 for any effect. For the last 10 minutes,
open up the aperture to max. This will give you star trails
with the end points as bright little dots. That will
help you identify the constellations in the print.
Watch for dew on the lens. If it starts to build up and
you can get power to the shoot site, dry it out with a
hair dryer while the lens is still open.
good luck.
