If the shutter is open for 1 min and the download time is 8 seconds then the percent of time capturing is 88%. If the shutter is open for 10 mins and the download time is still 8 seconds then the percent of time capturing increases to 99%. I'd have thought the probability of collecting the elusive photon must be higher if the shutter is open a larger percentage of the time?
