Celestron NexStar 8 SE Telescope

A portable telescope that is easy to use and will prove useful not only for observations made at home, but also for field trips. It is convenient to use and allows more advanced observations.

Celestron SE series telescopes are characterized by their construction in the form of short catadioptric optical tubes and single-arm lightweight azimuth mounts, which are equipped with a GoTo system. Such a system is an important advantage, as it allows automatic search for objects in the sky - especially useful for less visible observational targets. In turn, a RedDot type finder will allow you to easily locate bright objects in the sky.

The optical tube of the Schmidt-Cassegrain system has a diameter of 203 mm and a focal length of 2032 mm. The corrector plate has StarBright XLT anti-glare coating to minimize light loss. The azimuthal mount used is modified compared to the 4SE and 5SE models - the parallactic wedge has been removed and the size and weight of the head has been increased. Either 8 head-mounted AA batteries or an additional 12-volt power supply can be used to power the mount.

It uses a NexStar controller with a database of 38181 objects, with 9 rotation speeds. For proper operation of the system, it is necessary to manually set up to 3 reference objects, making it possible to search for both objects contained in the database and those defined by the user. The mount can be connected to a computer, making it possible to control it using popular astronomy software. An additional RS232-USB converter is required.

The high-quality Plossel eyepiece has a focal length of 25 mm and a field of view of 50 degrees. The SCT T-Adapter allows you to connect a camera. As an option, it is possible to connect the Star Sense automatic homing system, as well as the Celestron SkySync GPS module. In turn, the SkyQ Link module allows control via WiFi.
