8.ADDITIONAL COMMENTS:
	I startet with video CCD Modul. Target star (+11.4mag) was bright and
        clear enough on Notebook screen.
        But from 20h50 UT thin clouds on horizon dimmed the star and target
        disappeared in noise most of time. So I decided to change equipment
        within few minutes from video to visual observation.
