Wondering how many calibration frames you should take? The general rule is: the more, the better—up to a point.
- Dark frames: Aim for 20-30 to create a low-noise master dark.
- Flat frames: Capture 20-50 for a smooth master flat.
- Bias frames: Since they’re quick, grab 50-100 to reduce random noise.
Stacking multiple frames averages out random noise in the calibration itself, improving your final image quality. However, beyond these numbers, returns diminish and workflow slows down.
