I will try a garden-variety CMOS camera (a few are on my workbench, fortunately) and see if it works out acceptably. If not, I will seek out an ultra low lux CCD - I'll keep an eye out for wavelength sensitivity specs. On another note - is FOV for cameras normally measured diagonally, or horizontally? (I might be looking for either 16 or 12 degrees to match the M1).
