"Over the horizon" optical experiments

Since 2013, my health has precluded proper field experiments at 481THz or thereabouts (optical). I am just too wobbly. I tried once, but I just could not manage it sadly.

One of the things I enjoyed was experimenting with weak signal optical signalling over the horizon. My own tests used QRSS (slow CW) received on a PC . There was absolutely no sign of the optical signal in the sky, yet there was a clear trace visible on the PC. 

Had I been well, these experiments would have continued and far greater ranges would have been possible.
