High time resolution (> 5 Hz) observations recently opened new opportunities to investigate the tiny space rocks beyond Neptune known as Kuiper Belt Objects. Extensions of such technique will become a valuable tool to discover and characterize rapid optical transients, which have never been properly studied. Another very exciting application of high speed observation is in the area of seeing-damaged image restoration. Digital image signal processing techniques combined with recently developed zero read noise imaging devices can together deliver so called super-resolution images, previously available only through space telescopes. Compared to adaptive optics of high cost and very small field of view, this approach can be an inexpensive alternative and yet cover much larger field of view, making it possible to study dense star fields and detailed galaxy structures from ground observatories.
