----------------------------

MINTRON low light level CCD surveillance camera (0.005
lux typical in non integration mode) and 0.00005 lux in STARLIGHT
mode with 128 frame integration.)
Used with 200mm focal length f/2.8 lens. Field of view 1.86 x 1.38
degrees - stars down to mag +13 seen in "real" time, depending on
sky brightness.
Individual frames are video time stamped with GPS derived signal.
Images processed and measured manually.

NOTES:
---------
(1) "Experimental" session. Trying new optical setup for use with plane
    scanning. Unfortunately the MINTRON has so many dead pixels (that
    look like geostationary satellites) which makes it rather unsuitable
    for the task.  Faint geosats need more than the 2.5 seconds exposure
    maximum that the MINTRON can give.
(2) Lot of cloud dodging...

Cheers
Greg
