Equipment

The objective of the observation includes the precise determination of the moment of the disappearing and re-appearing of the light of an occulted star, observed from a well known location. Many of these stars have a brightness of 12 or 13 mag or less. The change of the brightness during the occultation shall be recorded with the shortest possible frame rate, getting the highest resolution in time. That's why larger telescopes with higher opening ratio are preferred for this purpose.
Nevertheless, there are many events with brighter stars, suitable also for smaller openings (see occultations).
Hereafter it is assumed, that a telescope (with tracking mode) and a portable computer (notebook) are available. For successful observations of stellar occultations, the following equipment is not mandatory, but recommended:
