The Gossen Lunasix/Lunapro is so named because of its supposed ability ti
meter in moonlight - the specs speak of metering from EV-4 which I think is
8 hours at f/64 (though I can't speak from experience).

However, before you jump in, perhaps a consideration of the reciprocity
failure characteristics of the film in use would be in order - would the
metering be of any better practical use than a 'rule of thumb'?

Are there light meters than can accurately meter a scene or meter the sky in
extremely dark nighttime conditions? Do such meters allow you to calculate
aperture/duration when the duration may be 8 hours long?
