The 203mm lenses are also available in 2 versions, the 203/1420 with a focal length of 1420mm is the f/7 version of the lens. Do the math: With Riccardi Reducer f/5.25 !!! A gigantic, non-obstructing astrograph with 8" aperture and 1065mm focal length. Only APM can deliver such optics!

The APM-LZOS Triplet SuperED Apo 203/1420 can also be installed in systems for smaller observatories. The performance is phenomenal: The theoretical resolution of well under 0.6 arc seconds can actually be achieved on corresponding nights and that is not an advertising slogan! The superbly polished optics will reveal details on the planet that you never thought possible. Observe deep sky objects binocularly, e.g. M13, M31 or h & Chi Persei, a real pleasure! You will immediately notice the enormous contrast, which enables you to perceive details that are not possible with other systems.
