Hold the universe in your hands with the Celestron NexStar 4SE.

If you're after a well-renowned beginner telescope, you can't go wrong with Celestron's orange tube design. The Celestron NexStar 4SE Computerised Maksutov-Cassegrain Telescope lets you go to, track and observe celestial objects with ease. With an 4-inch aperture, this telescope offers good light-gathering capabilities whilst maintaining an incredibly compact form factor. This means you'll be able to observe the craters on the Moon, Jupiter and the rings of Saturn. Beyond our solar system, the 4SE will use its motorised mount to automatically guide to and track hundreds of deep sky objects. Take it out to a dark sky site and prepare to be taken aback by the fascinating views of the 4SE.

With a sturdy, high-quality Maksutov-Cassegrain construction placed on a Computerised, Alt-Az Single Fork Arm, the NexStar 4SE offers impressive optical performance at a very reasonable price.

For even better and brighter views, consider the Celestron NexStar 6SE with a 6-inch aperture.

 

Fully Automated, Computerised GoTo Mount.

Featuring a database of over 40,000 celestial objects, use the included NexStar+ Hand Control to select exactly where you want your telescope to go and what you want it to track as objects move across the night sky. Perfect for both beginners and seasoned astronomers.

 

Featuring SkyAlign Technology.

The NexStar 4SE is perfect for beginners with an easy setup process. Simply input the date, time and your location and point the telescope at any three bright objects in the sky and your SkyAlign-enabled NexStar 4SE will identify its exact orientation and position in the night sky.

 

Easily Transportable and Easy-To-Use.

Thanks to the patented, single fork arm mount of the NexStar SE, the telescope is surprisingly portable and allows for a quick and easy setup. The 4SE is incredibly compact too, with the tube weighing just 2.7kg!
