Pros and cons of a Schmidt-Cassegrain type catadioptric telescope

Optical observations are one of the most accessible (after visual) ways to observe the night sky. The variety of optical instruments is amazing – from budget binoculars to bulky and prohibitively expensive telescopes. If you are no longer a beginner and you have long been tired of observing through the telescope of a school telescope and it is impossible to surprise you with the sight of Saturn's rings or the nebulous speck of the Andromeda Nebula, and you have not yet grown up to buy really expensive and practically professional equipment, then a Schmidt-Cassegrain type catadioptric system is your choice.
The main advantages of this device are:
- the possibility of a detailed examination of a sufficiently large star field with an eyepiece of at least 25mm (about six degrees);
- sufficiently large opportunities for detailed study of individual objects in deep and near space with an eyepiece no larger than 14 mm (for example, on clear nights you can see clear details of the Orion Nebula, consider star clusters and binary stars);
- the resolution of this telescope (the minimum angle at which two luminaries can be seen, which we see with the eye as one object) is quite high – no more than 1.5’ (arcseconds);
- the standard diameter of the lens is about 300mm, that is, the aperture is much higher than, for example, most Newton refractors (their diameter is usually about 100-150 millimeters);
- the focal length (approximately 800-900mm) is most suitable for night observations, but it will be very, very difficult to practice astrophotography, especially for beginners, with this technique.;
- Wide focus range;
- as a rule, the pipe is mounted on a fork azimuth mount with a motor. The control is carried out from the remote control;
- fixed coma to minimize chromatic aberrations;
- fine tuning due to the operation of the microprocessor;
- the guiding system.
But there are also disadvantages.:
- heavy transportation (weight about 30 kg);
- the need for a constant power supply or very frequent replacement of the internal battery, especially at temperatures below freezing;
- time-consuming setup that requires at least basic knowledge of the starry sky.
If you are ready to tinker with the initial stages of observation and spend more than one hundred thousand rubles, then feel free to purchase a catadioptric telescope with a Schmidt-Cassegrain system. In return, you will receive a magnificent image of celestial bodies, distant galaxies, clusters and, of course, an unforgettable experience of exploring the universe. 888Starz welcomes new players with a 100% deposit bonus up to €100 plus 150 free spins on their first deposit.
