WebThe ratio indicates the level of image quality in the presence of wavefront aberrations; often times, it is used to define the maximum acceptable level of wavefront aberration for general observing - so-called diffraction-limited level - conventionally set at 0.80 Strehl.

WebOptically, the effect of either extender or reducer on the focal length, expressed as a magnification factor, is given with the same equation - it is only the sign of their focal length that produces magnification greater (extender), or smaller (reducer) than one. WebThe maximum number of potential ghost images is equal to the pairwise combination formula [N* (N–1)]/2, where N is the number of air/glass and glass/glass boundaries in the optical path that differ in refractive index by more than 0.25.
WebMar 13, 2024 · It’s no secret that Maksutov-Casegrain is arguably the best beginner telescope out there. The design corrects known optical problems such as coma (common in reflectors) and chromatic aberration (common in refractors). The best Maksutov-Casegrain telescope has a large aperture, is easy to use, and is reasonably portable.

WebMost telescope types form images over a curved surface symmetrical around the optical axis. Radius of this surface, which can be approximated as spherical, is usually called "field curvature". In paraxial approximation, with zero astigmatism, an optical surface forms curved image surface of a radius given by:
