SUMMARY
Updating dark and bias master frames is essential for maintaining image quality in astrophotography, especially with cooled CCD cameras. Users recommend re-acquiring these frames a few times a year, particularly if regular shooting occurs. The degradation of camera sensors over time necessitates this practice to ensure optimal performance. The process of generating new frames is straightforward, allowing photographers to efficiently manage their equipment's calibration.
