That will be until we get true noiseless capture or noiseless photon multipliers ! - Can't wait !

if there is no read noise, a few hours of very short subs will yield exactly the same result as a few hours of long subs. The lack of any signal in a sub is not an insignificant result - it tells you just as much about the signal level as having a photon there. You just add up how many photons were detected in all of the subs and that's the signal - if there are subs with no signal, they do not contribute to the sum, but contribute to a calculation of the photon rate. mind you, 1/100 seconds is way beyond what is being discussed for DSOs
