The eyepiece field stop diameter (FSD), true field of view (TFOV), effective field of view (EFOV), apparent field of view (AFOV), telescope focal length (TFL) and eyepiece focal length (EPFL) are related by the following equations: TFOV=FSD*57.3/TFL; EFOV=FSD*57.3/EPFL; EFOV=TFOV*(TFL/EPFL).

Newt for the Web (Newt-Web for short) is a Newtonian Telescope Computer Aided Design program. It ray traces a Newtonian telescope design checking for vignetting, optimizes diagonal size, calculates baffle sizes and positions, and produces performance and dimensional data for construction.

newtonian telescope design planner (v/ns1.3) Use the reference "# nn" in each field in the diagram to identify the parameter of interest and then locate the associated "live" field with the corresponding number in the table section BENEATH the image to enter and/or review the actual scope data.
23 lis 2012 · Why do you need software to design a Newtonian, it is such a simple telescope to design that a normal knowlege of the optical principles is surely enough. Finding the diameter of the secondary is also very easy, and you do not need a computer to do this either.
This page lists various telescope related formulas and it calculates telescope & mirror parameters for you. It is primarily oriented to the Newtonian reflecting telescope, which is what most first time telescope makers build, although many sections of it are applicable to other types of telescopes. Since many telescope makers want to compare ...
Revolutions in telescope design are driven by dreamers. I created 'NewtDesigner' to design my telescopes, to make the best optimizations and trade-offs. Perhaps you'll find 'NewtDesigner' useful too. I also include my unique perspectives on telescope design, history and how a telescope works.
