Since September 2004 observations have been performed with CCD camera SBIG ST-7XE. The new more sensitive detector has 765x510 pixels of 9 micron size. The CCD matrix is cooled thermo-electrically 45 degrees below the case temperature - in practice 15 degrees lower than ST-7. The camera is connected to a control PC via a USB port what makes data readout very fast. The new detector is equipped with a near-Johnson V filter.

First regular observations, acquired with the new detector, were gathered between September and December 2004. 8 fields (each 2 x 3 deg wide) covering 48 square degrees at the boundary of constellations of Pegasus and Andromeda (23h27m30s<RA<23h56m30s and +29°<DEC<+37°) were monitored during 12 moonless nights. About 9,600 stars brighter than 14.5 mag were observed.

The accuracy of first observations is illustrated in Figure below where standard deviations are plotted versus magnitude for all stars observed so far in V band. Typical internal scatter at the bright end is 0.02 mag (previously 0.04 mag). As one can note the SAVS accuracy has been significantly improved.
