It is no surprise that the CCD’s best performance is with a single long exposure. What may be surprising is the Kepler KL4040 has a better signal-to-noise ratio than the PL16803 even with a single long exposure. The signal-to-noise ratio of the KL4040 is better than the PL16803 even when using short exposures that are stacked!
