Thanks for that Paul. I believe folk underestimate the amount of reflection one gets from even a black painted surface. At home with no lights on anywhere (within 8 klms) looking down a blackened cardboard tube with only a candle off to one side.. it shows, and thats just the human eye.. not as sharp as one of those electric ones. If you look at the Hubble Space Telescope they have an extended baffle system and I recon they must have an idea. So I recon we are on the right track.
Thanks again
alex
