Cameras using global-shutter CMOS sensors are particularly suitable
for imaging Sun, Moon, and planets. Compared to rolling-shutter CMOS
sensor-based cameras, their FPS could be slightly lower, because the
next exposure must wait for completion of previous image digitization,
while the rolling-shutter sensor cameras can start the next exposure
of already digitized image lines while still digitizing the rest of
the image. The inherent disadvantage of rolling-shutter sensor-based
camera is the fact, that each line of the image is exposed in
different time, while cameras using global-shutter sensors expose the
whole image in exactly the same time. For imaging of objects rapidly
changing their shape, the global shutter is a must. And the shape of
the observed object is somewhat changed also by seeing.
