A remarkable design with inherent third-order optical perfection, this basic arrangement of mirrors has been rediscovered several times since M. Paul's 1935 paper. Despite the Stevick-Paul's superficial resemblance to a TCT, all mirrors are coaxial. The unobstructed view in this design comes from using the optics "off-axis".
|Using a flat to fold the light path, Bob Novack of Pittsburgh, Pa compacted the design and eliminated the diagonal mirror. Bob's plans for this 6" f/10 are here.|
|Viewed from the eyepiece end, one notices the two finders on Bob's telescope. The finder on top is unity power. Bob is justly happy and proud of his telescope's performance|
