If one needs a 180 second exposure, you could achieve that by either stacking ten 18-second exposures, or say 90 two-second exposures. The stacking the two second exposures will produce a complete image, however it will lack the color fidelity and certain nuances of detail that the ten 18-second exposures bring to the table. In other words, actual SNR trumps virtual SNR (if stacking say night sky photos is the goal.) | |

There might be a small difference in it when you draw the power in one long haul instead of splitting it into a number of short stints. | |
