Stellar occultations are usually observed visually, but this can also be done photographically. Our method has some advantages:
– the obtained moments of contacts refer to the smoothed lunar limb,
– the error in the determination of contacts is calculable,
– the error may be less than in visual work,
– the reduction of photographs is fast, due to the application of an “on-line” computer [1].
In order to achieve all this, it is necessary to make a series of photographs of the Moon and the object being occulted before the first and after the last contact. This is a crucial step in our method, because the photographs must be of high quality. This demands two things:
– the images of the occulted object and the Moon must be reliably recorded and
– the illuminated limb of the Moon must give optimal darkening on the film.
