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.
