Step-by-Step Calibration Frame Integration

  1. Organize your files: Separate lights, darks, flats, and biases into folders.
  2. Subtract bias frames: Remove electronic readout noise first using a master bias frame.
  3. Apply dark frames: Subtract thermal noise and hot pixels with a master dark matching exposure and temperature.
  4. Correct with flat frames: Divide light frames by a master flat to fix uneven illumination and dust shadows.
  5. Stack and process: Combine calibrated light frames to improve signal-to-noise ratio, then proceed with color correction and noise reduction.

Following this sequence ensures your astrophotos are clean, sharp, and true to the night sky.
