[QUOTE="panos_adgr, post: 2508, member: 12"] It's a classic technique and you can find many tutorials in youtube. Some of the tutorials are made a bit complicated really with no reason. It is used as a technique also in daylight long exposure photography when an ND filter of 10 stop cannot provide longer exposures than 15'' or 20''. Stacking many exposures in Mean is as doing one exposure of the same duration as the sum of the multiple exposures. But you also have the benefit of noise cancelation. Noise is cancelled because of its random presence in each frame. The software identifies the randomness of noise and cancels it. You can also stack many photos of high ISO and reduce noise this way. I might open a thread of how I do it, at some time. [/QUOTE]
