Setting up the Vilnius photometric system with CCD detectors is extremely important for investigation of galactic structure since the system makes it possible to determine completely by photometric means spectral classes, absolute magnitudes, metallicities and peculiarity types of stars, even when affected by interstellar reddening. The paper describes the first observations made in the Vilnius system with CCD detectors at the Kitt Peak National Observatory and the US Naval Observatory Flagstaff Station. The paper also describes available software for the photometric classification of stars and investigations planned with the VATT telescope on Mt. Graham in Arizona. Some recommendations for users of CCD cameras for stellar photometry are given.
