General arrangement of the Hadley 114/900 Newtonian telescopeSide elevation. Parallel starlight travels to a 114 mm primary mirror 1,060 mm along the frame, reflects as a converging cone 770 mm back to a 45 degree diagonal mirror, and turns up 130 mm to the focal plane inside the eyepiece. Three rods tie four printed rings together; the mirror sits in a cell with three spring-loaded collimation screws.FOCAL PLANEØ114770130f = 770 + 130 = 900 · f/7.9STARLIGHT
