Kurt, try this approach: http://www.electrolamp.com/elpanel.html
Thanks for referral. I didn't see any prices on the Epanel. On the other hand, Patrick's piece of white board with a low flux light seems pretty simple and low-tech. <snip>
I've often thought about using the red material and lining the edge of my eyepiece and accessory cases with a strip of it, or making a chart illuminator from it.
I hadn't thought of that alternate use for white field box. A simple piece of Roscolux #83 diffuse or #27 red cut to shape and held between two pieces of black artist foam board should do the trick. I was also thinking about trying to use the white light box for holographic collimination of a Newt's secondary mirror. It would be the white light box with a piece of clear plastic printed with a 1/4" grid. http://web.telia.com/~u41105032/holographic/holographic.htm - Canopus56 __________________________________ Yahoo!
