Diagonal Mirror Minor Axis. it ray traces a newtonian telescope design checking for vignetting, optimizes diagonal size, calculates baffle sizes and positions,. D = (d/f) x lde where d=diagonal minor axis, d=primary diameter, f=focal length,. my question is, will my current diagonal mirror minor axis size (38mm) be adequate for a 2 eyepiece? it is the minor axis of an elliptical diagonal that will provide a 1/2 inch diameter circle of full illumination. Ellipses have a major (long) and minor (short). initially, he says the minor axis is calculated with: the shape of a diagonal mirror is an ellipse (oval), the shape a circle becomes when it is tilted back at an angle. a good place to start in your quest for the ideal secondary mirror is by figuring the absolute minimum diagonal size that will catch all the converging light rays from the telescope’s primary mirror. below is a large table of secondary mirror sizes computed for various sizes and focal ratios of primary mirrors from 6 to 48 in.
