Don't forget digital cameras on a fixed tripod, mentioned briefly on my old
web page.
You are better off if you can manage manual focus setting to infinity,
manual shutter speed (long enough to show trailing stars), and a good
selection of ISO speed to match the time and the f-number.

A difficulty with common lenses is that the f-number gets up above 4 even
with a slight zoom, and you might not have high ISO numbers to match your
maximum shutter time.
