I may be wrong, but I believe SNR on subs has the same diminishing returns.
Um, reread my posts. This is the point I've been trying to make.... Short or Long... the diminishing return is the SAME. Its a function of the rate of signal acquisition and the rate of noise acquisition whether in long subs or short subs, many or few.... You must use TOTAL integration time as a reference here.
Thats why many of us prefer longer subs than shorter as long as we are not clipping stars. You get to have your cake and eat it too... and in some cases, bring out fainter signals.
