No kidding
That's kind of what I was alluding to with my question.
Perhaps a more specific example is called for here, to help tease out what i'm trying to get to. If I capture 50 x 10min subs, both taken with my ST10 (6.8 micron pixels, average QE = 0.55) and my VC200L (f6.4, FL=1278mm, optical efficiency = 0.65)
a) Bin 1x1
b) Bin 2x2, followed by 2x drizzle integration
in example (b) the sensitivity is increased 4-fold as we have doubled the pixel size. Drizzle then spreads 1 binned super pixel out over four drizzle pixels. Does this then mean that we have produced an equivalent result to example (a). If not, then how specifically is the end result different?
Drizzle has the effect of increasing SNR.
