8.ADDITIONAL COMMENTS:
        Target star 2UCAC 30701154, +12.9mag, 38deg Elevation.
        Faintest object visible on live video fields (It=320ms)
        was target star.

        Only Clear glass filter (Astronomik) for CCD protection was used.
        
        Video evaluation accomplished with VirtualDub1.8.6, AviSynth2.5 and Limovie0.9.29b.

        To evaluate the 18 lossless HuffYUV compressed video segments (60GB/29GB) direct
        in Limovie additional the script controlled software AviSynth2.5 was used.

        No occultation detected (It=640/320ms)
