Are Maksutov Cassegrain telescopes good for astrophotography?
Among the variety of telescope models, the Maksutov-Cassegrain telescopes are great. They offer not a wide flat field but a high contrast in its center (which is where we most need it as a planet will always be small against the extent of the telescope framed field).
How does a Maksutov Cassegrain telescope work?
Maksutov telescopes are another variant on Cassegrain optics. In principle, they work just the same as a Schmidt-Cassegrain telescope. They have a spherical primary mirror and a secondary mirror. This design is the same.

Do maksutov telescopes have chromatic aberration?
Because of the thick corrector lens, Maksutovs suffer from more chromatic aberration than equivalent Schmidt designs, but the amount is still quite small until the focal ratio gets very fast. As with most Cassegrains, field curvature is an issue.
Does Maksutov have chromatic aberration?
Maksutov-Cassegrain Aberrations Because of the thick corrector lens, Maksutovs suffer from more chromatic aberration than equivalent Schmidt designs, but the amount is still quite small until the focal ratio gets very fast. As with most Cassegrains, field curvature is an issue.
What is a Maksutov-Cassegrain telescope?
A Maksutov-Cassegrain, also referred to as a Mak-Cass or more simply, a “Mak” telescope, is a member of the catadioptric telescope family and uses both mirrors and lenses in its folded optical design. One of the most popular Maksutov-Cassegrain telescopes on the market today is the Meade ETX.
What is a mk91?
Since I believe everyone is familiar with a C11, I will give some descriptive information on the MK91. The mk91 is produced by a small Russian firm by the name of Intes (not to be confused with the other Russian company, Intes-Micro).
Where is the focuser on the mk91?
The Mk91 uses a rack and pinion focuser with the knobs situated on top as opposed to the more traditional bottom location. Initial focusing becomes an effort to overcome 2 long-term habits – it’s a compound scope so one naturally reaches for the non-existent mirror-focusing knob.
How many apertures does a MaK-Cass Telescope have?
This very compact telescope comes in two apertures (90mm & 125mm) with optical tube assemblies that are very short when compared to other telescope designs. This means you can pack a Mak-Cass telescope in a small case that can travel with you, even on an airplane!
