It also sounds like the one offered by Edmund Scientific and mentioned on page 88 of the April issue of Astronomy Magazine, Steve. All the mag says is it is 0.3 lux, wired for 6.0 volts and video output. Its field of view is 45 deg and a resolution of 380 vert X 350 horiz. Edmund sells it for $195. I was wondering how useful it would be for astronomy, too.
