John A 1/3 inch CCD should, for an equivalent spatial resolution, be more sensitive (ie less noise at lower light levels) than a 1/4 inch CCD. Larger sensor = larger pixels = more photons per frame/field. Dearer though, and possibly more expensive lenses. Just my tuppence worth PeterS Remove my PANTS to repl. |
