Camera time efficiency simulation

6: High Dynamic and very weak signal, example 4

Lets play with the numbers. Say that we want high dynamic and a very weak signal. In this case the noise from background is 2.5 stronger then the weak object signal. Can the cameras handle that in theory? Note: This is just a simple simulation, lot of important things are not included, one example, static pattern.

Camera time efficiency, example 4

This simulation show that the perfect camera needs a little more then one hour for this weak object to reach S/N = 50. The real cameras from 2 to 5 hours. Could this be done in reality? Maybe I can do a test with my Canon camera how far I can come.

Looks good, but in reality very short exposures on weak object will be difficult to align, good tracking solve that, but then no dithering.
