Ok, some pix so you can see my latest experiment. It essentially uses a quad prism to split the incoming beam on the 80mm Achro so most of it gets to the webcam in the direct path but enough gets up through the 12.5 mm Ret EP so I can do visual pre-alignment. The real issue was to align the prism block accurately enough so both outputs showed the same view and was solid and stable. That's where Fred and his 3D printer made the essential element of it all.
There is still internal black painting to be done and some tweaks to alignment and finish but it works. I can put a webcam pic up on screen and view same pic in a wider feild view through the EP. Now just got to get rid of the clouds that came in the envelope with the optical block. How did you get them all in Fred ??
But I think I need purple LEDS to finish it off ......
