Tired of having a white light blinding me, or holding a torch in my teeth i spent $15.00 and bought a 10m redlight rope from one of those 2dollar type shops (everyones flogging them at this time of year).
Works a treat for an observatory, no more fumbling around while you setup yourself for the evening tripping over cables, not too bright, night vision intact,best of all its cheap.
i will put a switch on the wall next to computer to turn it on and off.
yep life is good
