Celestron NexStar 4SE Computerised Telescope

The Celestron NexStar 4SE Computerised Telescope is packed with high-tech features to make it as easy as possible for you as an experienced astronomer or a novice stargazer to enjoy superb views of over 38,000 celestial objects in the night sky.

You do not even have to know where to look to see the planets, stars and galaxies as you can deploy the fully automatic GoTo technology will locate and track your chosen object for you.

The Celestron NexStar 4SE Computerised Telescope will not only enable you to see with astonishing clarity and detail our Moon and the planets in our solar system but it will take you out into deep space to see features you probably never knew existed.

The SkyAlign technology makes it quick and easy to align the telescope in just a few minutes.

And whether you are setting it up in your garden or taking it out to a countryside hill away from urban street and building lighting, the telescope and its tripod can be quickly dismantled into manageable components for easy transportation and quick re-assembly onsite.

View the Universe's Most Impressive Celestial Objects

The 4-inch primary mirror has enough light-gathering ability to observe the best features of the solar system such as Saturn's rings, the cloud bands on Jupiter and specific geographical details on the surface of the Moon. When you want to view deep sky objects, take your 4SE to a dark-sky site to see such sights as the hundreds of pinpoint stars in the Hercules Globular Cluster, the spiral arms of the Whirlpool Galaxy and much more.

Revolutionary Single Fork Arm Mount

Sturdy construction from high-quality components give NexStar SE the computerised pointing and tracking accuracy needed to observe and follow your favourite targets with push-button ease. You can use the included NexStar+ hand control to locate nearly 40,000 celestial objects.

Alternatively, take a Sky Tour and let your telescope automatically show you the best objects currently visible in the night sky.

SkyAlign makes aligning your telescope as easy as 1-2-3. Just centre three bright objects in your eyepiece and press ALIGN.

Advanced Features Let the NexStar SE Grow with You

The NexStar SE is compatible with many high-tech accessories that are not included with this telescope but which you can buy separately if and when you decide you want their functions. For example, you could provide GPS coordinates to your telescope by adding SkySync or you could add automatic alignment functionality by adding StarSense AutoAlign.

If you want to explore the world of astro-imaging, the 4SE is a perfect choice. Its built-in wedge allows you to track long exposures. You can even remove the telescope's secondary mirror and replace it with a DSLR or astronomical CCD camera for wide-field images captured at f/2 using a Fastar/HyperStar lens assembly. Alternatively, if you are interested in imaging the Moon and planets, you could pair your NexStar 4SE with one of the Celestron Skyris cameras.
