Vilnius CCD Photometry of Southern Clusters: Some Preliminary Results
  The Vilnius Photometric system has been used with a CCD system only once before this study. Preliminary crowded field reductions of Vilnius CCD observations of the star clusters NGC~2004 and NGC~4755 (the $\kappa $ Crucis cluster) are presented, demonstrating the feasibility of using the filter set in this manner.
