The PiKon (Disruptive Technology) Telescope is based on the Newtonian Reflecting Telescope. This design uses a concave mirror (Objective) to form an image which is examined using an eyepiece. The mirror is mounted in a tube and a 45 degree mirror is placed in the optical path to allow the image to be viewed from the side of the tube.
The PiKon Telescope is based on a very similar design, but the image formed by the Objective is focused onto the photo sensor of a Raspberry Pi Camera. The camera sensor is exposed by simply removing (unscrewing) the lens on the Pi Camera. Because of the small size of the Raspberry Pi Camera board (25mm x 25mm), it is possible to mount the assembly in the optical path. The amount of light lost by doing this is similar to the losses caused by mounting the 45 degree mirror in a conventional Newtonian design.
