Maksutov's 1944 design was the first-published meniscus telescope design, and was published in the widely-read Journal of the Optical Society of America. This led to professional and amateur designers almost immediately experimenting with variations, including Newtonian, Cassegrain, and wide-field camera designs. There are many Maksutov designs that use a Cassegrain configuration, mounti… WebSep 3, 2024 · Telescope Optics - Rutten & Van Venrooij Section 9.2 (p87) "Close focusing in the SCT" The graph (Fig 9.8) shows the typical SCT when focused (using the mirror shift) can focus down to 50m before the Image blur exceeds the Airy Disk; this (table 9.2) equates to a mirror movement of 3.354mm.

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.
