Typically, you will need exposure times for the landscape at between 1 and 4 minutes, f/2.8, using 100 ISO film. The exposure times for this differ so widely that I can't possibly give a correct value; it depends a.o. on lunar altitude, cloudiness, light pollution, lunar phase, time of year and day (night), albedo of landscape, etc. So, use your camera's exposure meter, and expose 1/2 to 1 stop longer than indicated to account for the film reciprocity error. Make sure you also bracket your exposures (one stop less and another with one stop more, to experiment).
It is better to choose a higher aperture such as f/5.6 and f/8 combined with a longer exposure time, so your photo will be sharper and show less vignetting.
For the moon, the exposure differs too, and this is even more difficult to determine because of the various phases of the moon. The brightness of the moon is not just the percentage of disk illuminated! Due to the dry-heiligenschein effect and retro-reflective minerals on the lunar surface, the full moon is much more bright than one would think based on phase angle. So, I'm giving you a formula to determine the proper exposure to within 1/2 stop or so. This formula worked well for me.
t = F2 / (K * ISO)
- t is the shutter speed in seconds
- K is a constant: 20for crescent moon 40for first/last quarter moon 100for gibbous moon 200for full moon
- F is the focal ratio (e.g. F=16 for f/16)
- ISO is your film speed, e.g. 100.
So, say you are using a 1000mm lens on f/11 with 100 speed film for the moon, and the moon is gibbous. Then t = 112 / (100*100) or t = 121/10000 sec, or about 1/80 sec
