It runs on 12 volts and puts out an S-VHS signal. I have built a separate power supply for it with full voltage regulation and a gain control. The camera can be operated at the end of 100 feet of remote cable easily. The camera can be used with four different lens arrangements. One is the projection tube shown in the first picture.
Rigidity is essential because of the large magnifications involved in planetary imaging.
The four projection lenses shown fit into the tube at the location shown by the set screw. The lenses are inserted from the camera end and locked into place with the set screw. They are of course used in the retro projection orientation to ensure the best possible projection quality. True projection lenses give superior quality to eyepiece lenses which are not designed for projection use. Some of the photographic references given on this web site describe the use of projection lenses in more detail.
