Abstract

This article describes a novel procedure for the photometric calibration of an astronomical image data taken with a consumer level digital reflex camera (DSLR). A proposed algorithm is based on the measured spectral characteristics of the sensor of a digital camera and the known spectral transparency of the filters of the target photometric system. The method should allow calibration of light curves of stars of different color indexes. The article also mentions the mathematical simulation results and the preliminary results of observations with a DSLR camera.
