Abstract:
    We study the variability of the optical flux from the peculiar
    Galactic source SS 433 based on observations with the Russian-Turkish
    1.5-m telescope. We describe in detail the technique of high-quality
    photometric measurements with a time resolution of 0.3-1s using an
    ordinary CCD. Through test observations of non-variable stars, we show
    that atmospheric turbulence introduces no significant distortions into
    the light curves. Therefore, such data are well suited for studying
    the aperiodic variability of various objects.

Description:
    SS 433 was observed at the RTT-150 telescope with a CCD photometer, as
    was described above, mainly in the summer of 2005. In addition, a few
    observations were also carried out in the summer of 2004 and the fall
    of 2005. The observations were performed in the R band.
