Abstract

The technological advances and the increase of the collecting are of the modern telescopes made it feasible to obtain high signal-to-noise (S/N) observations of “fast” phenomena, which was not possible earlier, even for bright objects. Although the natural application of the high timing resolution technology is to study the “fast” events, it helps to increase the S/N for events with fixed length because—indeed, the “fast” observations are only meaningful with small “dead” times between the individual integrations. Therefore, the “fast” instrumentation guarantees high filling factor, or high cadence. In other words, for a fixed duration events, such as transits, occultations, etc. the observer can collect more data with respect to the “slow” instrumentation. Last but not least, the shorter integration times feasible with “fast” instruments allow to bridge the calibration gap between 1 2 4 8 42 m telescopes that rises from the fact that most primary calibrators used today were developed on smaller telescopes.
