Celestron's Schmidt-Cassegrain optics:

Despite the long focal length of the Schmidt-Cassegrain optics, the tube has a very short design, making the system a compact telescope characterized by extremely light transport characteristics. The light strikes an aspherically shaped Schmidt correction plate and is then thrown onto the spherical main mirror. This reflects it in a secondary mirror, which returns it to the primary mirror. The light beam now passes through the main mirror, which has a central hole. In this way, the light is launched to the focuser located at the rear end of the tube. This means that the system is closed and does not suffer from air turbulence that could harm the image. Of course, this also provides optimal protection against dust. The Schmidt plate is multi-coated, ensuring bright, low-reflection images.

This optic offers a very good image, the contrast and sharpness are convincing and offer great fun, especially when observing the moon, planets or planetary nebulae. Overall, the Schmidt-Cassegrain system is a very good and robust all-round device for observation and photography. The sight at the lower end of the tube allows for easy orientation. The telescope can also be optimally used for occasional terrestrial observations (for example, at close range for bird watching). Celestron SC optics have an aperture ratio of f/10. An optional reducer can be used for astrophotography to make the optics "faster" and increase the field of view.

The main mirror focus ensures a very wide range of sharpness, allowing almost any accessory to be fitted. Two preloaded ball bearings are used in the positioning mechanism to focus the main mirror to minimize "mirror drift" (a typical problem when using simple bearing shells). The use of high-quality materials, such as CNC-milled components from aluminium, cast steel and stainless steel, ensures high stability with little weight, so you don't need a very heavy mount, as may be necessary with other optical designs. .
