then I think that we agree
- If you integrate more within a sub (by making it longer), the SNR result after stacking a few of them is the same as integrating by stacking more shorter subs - but you get other advantages from shorter subs (that is if short and long subs are all sky limited). What matters is the total number of photons detected, not how they were collected.
Does that sound reasonable?
