I am well aware of all sources of noise. I do have a degree in Physics.

Do you think that nutters such as myself would buy fast optics just to overcome these limitations of signal to noise if they did not work?

The only way to overcome or minimise Shot or Poisson noise is a fast optic where the stream of photons are like a river rather than a noisy trickle!

Drizzling is just upsizing and stacking!
