Celestron NexStar Evolution 9.25 "Telescope

New technologies have come to this Celestron telescope. The Nexstar Evolution telescope models incorporate an internal router with WIFI connectivity . This way, no matter where we are, coverage will never be a problem in operating our telescope. Wherever we are, we will be able to use our spectacular telescope through the IOS or Android tablet or smartphone through the Celestron app, which incorporates the fast SkyAlign alignment system .
The easiest and most spectacular telescope to use in history!
Forget about batteries or external power supplies. For the first time, the Nexstar Evolution model incorporates as a world first its own integrated lithium-ion battery with a range of 10 hours of continuous observation. In addition, through the USB charging port you can connect other devices that you need to power during the observation.
The Celestron Nexstar Evolution 9.25 "model mounts very easily and quickly and as a whole is a lightweight and light bulky telescope compared to a 9-inch diameter telescope. It is precisely thanks to its large diameter with optical system Schimdt-Cassegrain which makes it a very bright telescope producing bright and sharp images through its Starbright XLT optical treatment It can also be a telescope to start in the world of astrophotography , although ideally you should adapt a Equatorial wedge, being the only fork telescope that incorporates a bisinfín system with improved motors.In addition, thanks to the precision of guidance we will hardly have to make corrections in hours obtaining bright and sharp images like planets like Jupiter or nebulae like Orion, among others .
