That is interesting, and I take your point that stacking 100 millisecond exposures for DSO's captured with a standard CCD system is just adding noise(I have empirical evidence to support this;-). I guess my question would be, if a 20 minute exposure with a standard CCD is equivalent to a stack of 100 ms exposures totaling 20 minutes, what is the motivation for doing the short exposures? Is the benefit improved resolution due reduction of the influence of atmospheric instability? I know that is a big issue for planet imaging, and why the planet cams are generally short exposure/high frame rate cameras. I have/perhaps erroneously been under the impression that this was less of an issue for DSO imaging. Just curious.
