Is a Maksutov Cassegrain a refractor or reflector?
Another catadioptric telescope that is widely used for astronomy is the Maksutov-Cassegrain or “Mak” for short. Unlike refractors and reflectors, this telescope design does not suffer from coma or chromatic aberration. These telescopes are great for lunar and planetary viewing, as well as terrestrial daytime use.
How do I choose a catadioptric telescope?
Yet, choosing a catadioptric telescope can be a daunting endeavor. Buyers should consider three main factors: requirements, specifications, and budget. Aperture, magnification, and optical quality are also essential factors to consider.
Is Maksutov Cassegrain reflector?
The main differences between maksutov-cassegrain telescopes and refractor deceives are as such : Maks utilise both a glass lens and mirror whilst Refractors only use glass for their lenses. Maks can have focal length around 5 – 7 times the length of the tube.
What is a Maksutov-Cassegrain telescope?
90mm aperture Maksutov-Cassegrain telescope gathers enough light for beautiful views of brighter deep space objects like globular clusters, nebulas, and many bright galaxies Nifty tabletop base provides a stable viewing foundation you can set on any sturdy table, or even attach it to a field tripod with a 3/8″ or 1/4″-20 threaded post
What is the Maksutov C90?
The C90 is a Maksutov Cassegrain scope of 90 mm aperture and 1250 mm focal length, giving it a focal ratio of f/13.89. It has a tube length of c. 40 cm and a weight of 2.3 kg. The telescope has a Celestron Lifetime No Fault Warranty, indicative of the ruggedness of the design.
What is the Meade ETX 90 telescope?
The Meade ETX 90 is computerized Maksutov-Cassegrain telescopes from Meade Instruments with a 90mm aperture and 1250mm focal length (f/13.9). It’s part of the ETX Observer range that also includes the ETX 80 and ETX 125 models.
What is a Schmidt Cassegrain telescope?
This Schmidt Cassegrain telescope is another Celestron’s model that features an eight-inch aperture that has enough light-gathering power to provide you with a beautiful view. You can use it to observe lunar and planetary objects and even different deep-sky objects.
