A web-cam on the finder is a useful arrangement.  Since i already have a  9×50 finder and a suitable camera, i bought one of these from FLO:×50-finder-to-t-adapter.html.
Agreed, Its helpfull to have some form of dark frame subtraction to remove hot-pixels if the web-cam is used with longer exposure settings.   False stars can be confused with real ones !
