I made my video finder from 50mm f4 Surplus Shed optics. I liked the way the Orion finder scopes focus by screw mounting the objective to to the barrel of the scope. In other words, the objective rotates to find focus. Anyway, I duplicated that idea, pictures below.
The camera is a KT&C 350BH which is the PAL flavoured PC164C (NTSC) which is a rather famous cam. in occultation community. It can see down to about mag. 8 at 25fps in the finder.
I do most of my astronomy with some sort of vidcam in the 10" and both cams are fed to the monitor and I can switch between the scope and the finder as required.
