FAI Calibration Data for 50 cm Meniskus Maksutov telescope

This service collects plates taken for calibration purposes on FAI's 50 cm Meniskus Maksutov telescope. Calibration frames are used for correction and enhancement of astronomical images. They allow the conversion of optical densities of an image into relative intensities and subtract the background radiation, making the data suitable for scientific analysis.
