pretty cool looking machine Mitchell i have a finder also i just need to adapt it to my tester sort of variation of the stellafane one with my own attitude. i think as far as different color LED's one might make a wheel of sorts (sort of like A filter wheel) rob has his figured out and he gave me an idea on how to attach the finder with PVC pipe as well as the ronchi screen. i think this tester will be in a continual state of flux until i get it the way i want it. but they are a necessity in my book.
