I bought a PC164C .0003 lux b/w security camera from SuperCircuits. Mounted this on my rail along with a Celestron slow motion tripod head which gives adjustment knobs for altitude and azimuth. The Camera has a 55mm F1.2 camera lens attached which gives it a field of view of about 5x7 degrees.
Here is a picture of the camera head.
The video from the camera passes through a video crosshair generator and then a distribution amp. From there it feeds a 12" monitor at my observing position, an ATI frame grabber card in the scope control PC and finally a small 'rover' display which is a 4" TFT LCD Monitor with a 30' cable which can be carried out to the scope. Here a pictures of these:

The crosshair generator is visible under the lamp and the 12" monitor on the right. |

This is the portable 'Rover' display. It can be carried to the scope for adjusting the finder, collimating via video. Whatever. |

Here is an image composed of 400 frames grabbed by COAA's AstroVideo I didn't bother with darks thus the streaking. The image is of my artificial star 57 meters distant. A simultaneous view through the main scope appears on the artificial star page. |
