Be sure to watch the videos.
The key to the system is the software (there's a basic freebie version available) and the camera which they recommend, a NexImage X2, and of course, a COTS (commercial-off-the-shelf) motorized catadioptic 'telescope'. (middle of page, 2nd photo on right)
This technology originated in the DIY astronomy hackers community over the past 20yrs, and recently, there has been a boon of airplane watchers, a bit of a weird hobby, where folks try to identify and match aircraft tail numbers to flight plans, and then they modified their hobby to use CCD video-cameras mounted on motorized astronomy telescopes. But outer-space object viewing telescopes have a too small viewing aperture and the slew-rate is too slow, so a modified motorized telescope with a catadioptic lens were developed to replace those. The average zoom range is around 1000 ~ 2500 mm, which is useful for within-atmosphere object viewing/videoing. One version uses a joystick to aim the lens while while watching through a finder-scope (little more pricey...~$1500).
Got any idears what these plane-spotting auto-object-tracking motorized video cameras systems might be useful for?
Hah hah hee hee!
