Web9 Aug 2024 · With full-frame CMOS sensors on reflector telescopes this seems to have removed the vignetting. Capturing around 30 frames of each of the darks, flats and biases works well, and after processing they are saved as masters for reuse. This cuts down on processing time as images from large format cameras can take a long time to process in … Web24 May 2024 · This calibration step removes two things: First, your master dark contains the same dark fixed-pattern noise that your master bias frame does. It also collects dark current, and more pattern noise called DSNU (Dark Signal Non Uniformity). Individual dark frames also contain their associated shot noise with that comes along the dark current.
