[QUOTE="Drakkith, post: 6141729, member: 272035"] The resolution does not depend on the number of photons. Instead, the 'quality' of the image increases as you gather more light. A short exposure is very 'grainy' and has a low signal-to-noise ratio compared to a long exposure. None. :wink: Resolution is a function of the size of the optical system, specifically the diameter of the aperture, and the size of the pixels on the sensor. Smaller pixels give higher resolution, as long as your optical system can bring the size of the airy disk down to approximately the same size as the pixels or smaller. [/QUOTE]
