CPU load when stacking images
Posted: Sat May 28, 2022 2:48 pm
I was asked general question about the loading of the computer's CPU as one accumulates images during a live stack:
When one does live stacking for EAA, and a new image comes in, I know it will calibrate that image… But then does it just add that one image to the existing stacked image? Or does it have to re-stack all of the previously calibrated images into a new stack?
I’m wondering how much processor and memory are used as the stack grows throughout the evening. Basically, is adding a new image to the stack the same amount of effort for each new image, or does it grow linearly in it’s demand throughout the evening?
...meaning that as the stack gets larger, does it require more and more processing with the CPU? My guess is that it doesn't and that the situation that would put the most load on the CPU is if one is trying to capture images at a high rate with a large camera for example, when one is trying to do lucky imaging for planets, solar.
