Abstract
This thesis presents an algorithm for automated photometric calibration of all-sky DSLR camera systems using plate solving. The system calculates instrumental magnitudes in the R, G, and B bands for multiple stars throughout different nights and locations, and are subsequently compared to catalog values from SIMBAD. Photometric zero points and colour terms are derived to correct for systematic offsets and colour-dependent effects. The accuracy of the calibration is assessed through statistical analysis and visualised using calibrated absolute magnitudes for each colour band. The results demonstrate the reliability of using a DSLR camera for quantitative sky brightness and colour index measurements, enabling its use for long-term monitoring of night sky conditions and light pollution.
