Celestron Schmidt-Cassegrain SC 203/2032 Telescope NexStar Evolution 8

Evolution: The next step in portable telescopes!

Integrated WLAN module: Instead of using the manual control box, you can also control the NexStar Evolution wirelessly with your iOS or Android smartphone or tablet. Use the free Celestron SkyPortal app, including the planetarium view and SkyAlign! Of course, you can also operate the telescopes in the classic way using the NexStar hand control.

Lithium Iron Phosphate (LiFePO4) Battery: Forget the clutter of cables or carrying around an expensive "power tank"! The built-in (but replaceable) battery powers the telescope for one night (ten hours) and even allows you to charge your smartphone via a USB port. You can recharge the built-in battery with the included power supply.

Even Better Ergonomics: The innovative product design introduced by Celestron with CPC telescopes can now be found on NexStar telescopes as well. In addition to the reinforced drive, this includes many "little things" that make observing more pleasant: A very stable tripod whose accessory tray does not have to be removed to fold it completely. The tripod legs have indentations so you can extend the legs by the same amount. The thumbscrew wings are turned inward so you don't get caught in the dark. The mounting table serves as an eyepiece tray and has been provided with a rubber pad for this purpose. The very subtle red light helps you find your accessories safely. Thanks to the carrying handle on the fork leg and the handles around the base of the fork, handling is very easy and comfortable.

Description

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 large focus area, making it possible to fit almost any accessory. 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 required with other optical designs. .
