My 30-line full-colour system is now complete and in my estimation, satisfactory at last.
Thanks to the use of an efficient dichroic splitter block and three photomultiplier channels, the camera works in very dim light. This allows comfortable televising and viewing of the picture at the same time. Indeed, best results are obtained using just the camera's built-in lighting, which consists of low power fluorescent tubes for the blue and green and under-run orange-glowing 'spot' lighting for the red. In general, picture quality now approaches that obtainable when using a standards converter. The colour fidelity is quite accurate. Both the camera and monitor use laser-cut discs with square holes, for a 'lineless' raster.
I should like to thank all the club members who provided parts, suggestions and know-how, and without whom none of this would have been possible.
On (another) topic, that of of the Robers-Brown colour standard, there is a thread starting here, which I feel can best be answered by more knowledgeable club members than I....
