Top Calibration Frame Mistakes to Avoid
- Mismatched Conditions: Using different exposure times, temperatures, or ISO settings than your light frames.
- Too Few Frames: Relying on single calibration frames instead of stacking multiple to reduce noise.
- Improper Flat Setup: Uneven illumination, changing focus, or altering the optical train between flats and lights.
- Bias Frame Confusion: Using bias frames captured at different gain or readout speeds.
- Mixing Sessions: Using calibration frames from different nights without matching conditions.
Stay organized and consistent to ensure your calibration frames enhance rather than harm your astrophotos.
