Dark - definition of dark by The Free Dictionary

WebFirst, it is dark, meaning that it is not in the form of stars and planets that we see. Observations show that there is far too little visible matter in the universe to make up the 27% required by the observations. Second, it is … WebMay 24, 2024 · The dark current’s shot noise is also in our light frames, but we can only remove this noise by stacking lot of light frames. When we subtract a dark frame, we remove hot pixel offsets and the dark current offset, but we can't subtract the dark current's shot noise — stacking is the only way to remove shot noise of any kind. ...
