Hi Bob,
Using a calibrated camera on the Sun is a good system to point the antenna on the Moon only when there are no clods and when the sky is clear.
On the other side a well calibrated control box on the Sun Noise is a goood system to point the antenna at the Moon with any wheader condition even with clods and this make the difference.

I'd say that differently...
Nothing wrong with using the camera. But your point is well taken to calibrate the camera to the BEAM by first pointing at the sun. Then (if your camera survives) the camera is a perfectly good aiming device for the moon and it eliminates any errors in the Antenna controller and pots. Bob

To mount a camera on a beam in order to locate the moon to work EME is a very bad procedure.
The correct procedure is to point the antenna system toward the Sun and get the maximum Sun Noise on receiver.
As soon the maximum Sun Noise is received please calibrate the Azimuth and the Elevation of your control box relative to the Sun position.

Please don't ya'll laugh too hard at me. Has anyone ever mounted a camera on a beam? Now I am not trying to see AO40, but I would like to simply double check the location of my beam for eme. If anyone has mounted a camera on a beam, I would be interested in what you used. Yes, I know all about beam width vs the moon. I just hate to call CQ with my beams pointed to the ground due to some Murphy type of failure.
