I am just curiuos as how this is possible. Is it a special CCD chip. I know it is a video system so it is not designed for proper imaging such as the fantastic results you display Peter but I ordered one to use with my young family to have fun with in our light polluted backyard in Brissy.
Keen to here back from your expert opinions on the way these things work, thanks again.

The CCD chip would most likely be a common CCD chip from one of the big name CCD chip manufacturers. What differentiates the mallnicam from other cameras (according to their website) is "Unique Custom Manufactured High Gain Circuitry Not Found on Any Competitor Video CCD Camera", which when combined with a high QE CCD and peltier cooling, allow alot of data to be acquired with relatively short exposure times.
In simple terms, I guess it is like taking the image and doing some image processing (similar to a stretch of the curves in photoshop to bring out detail) except it is doing it on a hardware level.
