Accuracy + Comments code: HH:MM:SS.ss S.ss S.ss S: 01:12:05 E: 01:16:08 5.TELESCOPE: Type: Newton Focal length: 1200mm Aperture: 254 mm Magnification: video/primary focus/recorded field 1112" x 830" Mount: Equatorial Motor drive: Yes 6.TIMING & RECORDING: Timekeeping: GPS 1PPS Garmin18 LVC + KIWI-OSD Sensor/Camera: WAT-120N, CCIR, 1/2" Sony CCD-Sensor ICX419ALL Mode of recording: integration time=640ms, Video CCIR, AVI, YUY2, Huffyuv, Device of recording: Xpert V-Stream Videograbber USB2.0, Notebook Harddisk Time insertion: KIWI-OSD 7.OBSERVING CONDITIONS: Atmospheric transparency: very bad Wind: 0 - 0.5m/s Star image stability: fair Minor planet visible: No (integration time 640 ms) Temperature: 290 Kelvin (+17 deg Celsius) 8.ADDITIONAL COMMENTS: Haze and thin clouds appeared on horizon after setup. So integration time had to be increased to 640ms (16 x frametime) Video evaluation accomblished with VirtualDub1.6.14 and Limovie0.9.24 No occultation detected Target star TYC 6866-02020-1u, +11.5mag, 09deg Elevation Only Clear glass filter (Astronomik) for CCD protection was used Integration time was 640ms (16x frametime) Limit on integrated video frames TYC 6866-02018 +12.3mag 3-D Position and timing Garmin GPS18 LVC Receiving 08 satellites Horizontal Dilution of Precision 1.7 Geoidal separation 44.4m Gerhard Dangl gerhard@dangl.at www.dangl.at/ +--------------------------------------------------------------------+
