    Video of the GC-3 flashing LEDs. LedSourceGC3.mpg This 30-second clip was taken as Fred passed from 13,700 to 14,500 feet. The instrument is a CCD camera at the prime focus of a 50 mm f/4 objective. This telescope was mounted piggyback on a Meade LT-6 with tracking mount. Pointing is executed by the LT-6 under the control of a MatLab program that uses the telemetered GPS data stream as input.

    Images of the Celestron Mak500 in action. The CCD imager mounted is a hacked Logitech QuickCam. I've also tried a more modern video ccd imager with optically similar results. The finder scope is a homemade 50 mm f/3.6.

    The focus is as good as it gets. Low quality of this imagery may be due to a linear combination of the following:

  • The guy who sold the telescope to Chris knew what he was doing.
  • Poor seeing. Zenith angle about 60 degrees and windy.
  • Mounting shake due to wind.
  • Unresolved scattered light issues in the newly fabricated back end.
