You might want to ask the question on sci.astro.amateur too and take a
look at the unconventional use of webcams for astronomy on the QCUIAG
site (true DIY stuff using and adapting cheap webcams)

There is a lot of interesting low light stuff there.



In astronomy the low intensity object is tracked so it always occupies
the same pixel on the camaras sensor allowing for long exposures or for
the combination of many frames. You can do the same with any CCTV
camera attached to your house assuming that everything in the scene
remains static.
