[amsat-bb] Re: Camera on an antenna

[Robert Bruninga]

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
