How many flats do you need for astrophotography?

January 21, 2022, 12:25, asked: Ryan Wightman

Personally, I have found that 20 flat frames are enough to create a useful master flat file for DeepSkyStacker to calibrate your image. Since these are so quick to capture, there is no harm in collecting 20 or more frames for each session....

  1. Shoot at the same ISO/Gain as your light frames.
  2. Keep the camera connected to the scope/lens.
  3. Maintain the same focus as light frames.
  4. Shoot a minimum of 15-20 flat frames.
  5. Temperature is not important (It is with a cooled CCD)
