Catadioptric telescopes use a combination of lens and mirrors to focus light. Compact catadioptric designs, such as the Schmidt - Cassegrain or Maksutov telescope, have become popular with amateurs in the last 30 years. The Gregory Maksutov-Cassegrain shown at right uses an aluminized spot on the Maksutov corrector lens as a secondary mirror ...
The benefits of this quadruplet-lens telescope are the lack of need for a field flattener, and the high-quality astrograph level focuser. Without being able to use each and every telescope on this list first hand, it is impossible for me to provide a complete review of each model.
Dec 26, 2015 Maksutov-Cassegrains were popular back in the 1960s, but even then only a handful of amateurs made them -- and for a very good reason. Maks are not easier to make then a refractor. The corrector has very tight tolerances in terms of radii, center thickness and centration. The corrector substrate has to be of high quality in terms of ...
Jul 14, 2021 The secondary and corrector lens is situated at the top end of the telescope. Light enters the telescope and reflects off the primary mirror towards the secondary and corrector lens. Its then reflected back to create a narrower light cone that enters through the perforation in the primary mirror to come to focus behind it.
Sky amp Telescope Craig Michael Utter. An instrument can possess the finest objective lens or mirror, but the exquisite detail at its focus will not be faithfully conveyed to the eye or camera unless an eyepiece of equal quality is used. It may seem like a small link in the chain, but it
