I get why LENR would cause breaks in both of these, but I am curious why multiple exposures without reading out the sensor is better than a continuous long exposure of the same (as the cumulative) length?
Stacking separate exposures improves signal to (thermal) noise ratio by reducing the noise accumulation time in each. I would have thought that by not reading out the sensor in between, multiple exposures are the equivalent of a long exposure?
Or does the camera read it out each time and do some kind of average or addition itself?
