Re: Dark Nebulas Detection - Integration time and subexposures
We know that the SNR increases with the square root of the number of subexposures. This means that you're going to get diminishing returns in SNR the higher their number goes; at some point you'll reach an asymptote for that length of subexposure. Then how can it be possible to match the SNR of an o...
