A fixed tripod does not follow the rotating sky. That makes it a simple way to photograph a wide star field or deliberately record star trails. Decide which result you want before choosing an exposure length.
Check the basics in a test frame
Place the tripod on stable ground and compose while you can still see the foreground. Use a delayed shutter or a compatible remote release. Focus carefully on a distant star using the camera's available magnified view, then check the captured frame rather than trusting the position of a focus ring alone.
Try a short exposure and inspect the stars at full size. Longer focal lengths and different parts of the sky reveal motion at different rates, so a single universal shutter rule is only a starting point. Adjust exposure, aperture and sensitivity for your own camera, lens and sky brightness.
Choose points or motion
For points, shorten the exposure until movement is acceptable for the output size you need. For trails, keep the framing fixed and follow your camera's supported long-exposure or interval sequence workflow. Read the manual for battery, file and noise-reduction behaviour before an unattended sequence.
Keep the original images and a short settings record. Check that a foreground is legally accessible at night and that tripod legs do not block a path. Do not add artificial light to a shared dark-sky site without agreement. A technically modest result with sharp focus and a clear composition is a useful basis for the next attempt.
