Calibrated extinction and color correction parameters.

Validated calibration with standard stars from Landolt's catalog.

Abstract

We have done photometric calibration of the 60 cm Nedeljkovi\'{c} telescope equipped with FLI PL 230 CCD camera, mounted at the Astronomical Station Vidojevica (Serbia), using standard stars from the Landolt's catalog. We have imaged 31 fields of standard stars using Johnson's $BVRI$ filters during three nights in August 2019. We have measured both extinction and color correction. Relating our calibrated magnitudes to the magnitudes of the standard stars from the Landolt's catalog, we have achieved accuracy of 2\%-5\% for the $BVRI$ magnitudes.
