   Timekeeping: KIWI-OSD with GPS Garmin 18 LVC
   Sensor/Camera: Videocamera WAT-120N+, CCIR, 1/2" Sony CCD-Sensor ICX419ALL
   Videocamera settings: Shutter mode=High1, Gain=HI, Gamma=OFF
   Device of recording: Personal computer, Imaging Source DFG/SV1 PCI, composite-video, Virtualdub software, saved on Harddisk
   Mode of recording: Integration time=0.040s (25 Img/s), CCIR, Huffyuv
   Time insertion: KIWI-OSD

7. OBSERVING CONDITIONS
   Atmospheric transparency: good
   Wind: light, because of wide field position
   Star image stability: fair
   Minor Planet Visible: yes, during the event

8. ADDITIONAL COMMENTS

One comparison-star was in field of view.
Tangra was used to analyze the avi-file.
Occular was used to plot the "signal minus background" versus time and evaluate the D and R times. Single frames (and not fields) were used.
Because of the use of an integrating video camera in shutter mode "High1" a correction of -0.040s was used (the so called "Dangl correction").
