Re: Optical COmms experiment



Would a "strobe" light of some kind provide better margins due to
it peak power output? Maybe incorporate a small parabolic reflector
to focus the beam a bit... Instead of CW, maybe it could send "Real
Morse," which would be compatible with short duration light flashes.

We could have a LOT of fun with small telescopes hooked to CCD's.
My hand made, wide field, 6" f4 newtonian is gathering dust :)

Imagine putting that tube on my AZ-EL boom!
