WebOct 12, 2024 · From what I've read, (e.g. Arne's discussion of QHY600) binning often reduces the dynamic range of a camera. For example, if the well is 100,000 e- per pixel, the binned 2x2 pixel is still 100,000 rather than 400000. As a result, binning reduces dynamic range and means that faint targets cannot be imaged that perhaps could be imaged in 1x1 mode.
