I'm selling a Pi Prism Pre-built. If anyone wants one send me a private message.
New Video of the Pi Prism Added new 16.5 x 38 DCX lens. With the Penta-prism the people facing you do not see the screen (mainly for privacy). Also I made the eyepiece bridge longer.
Blurry Picture taken with iphone (the screen is crispy clear irl)
