Celestron NexStar 4SE Computerized Telescope

Weighing in at only 21 pounds, the Celestron NexStar 4SE combines extreme portability with the convenience of Celestron's NexStar computer go-to system and tack sharp Maksutov-Cassegrain optics.

The Celestron NexStar 4SE combines extreme portability and tack sharp Maksutov-Cassegrain optics with the convenience of Celestron's NexStar computer go-to system. This is an ideal telescope for beginners who are primarily interested in the moon, planets, and brighter deep space objects, or for urban dwellers who are limited to these objects by local light pollution conditions. We find the Maksutov-Cassegrain optics of the NexStar 4SE to be preferable to Schmidt-Cassegrains when viewing the moon and planets because they offer higher contrast.

Celestron NexStar 4SE: Excellent for Beginning Lunar / Planetary Observers

Let a Celestron NextStar SE help you find the moon, planets, thousands of stars, and even galaxies and nebulae at the touch of a button! In the tradition of Celestron's famous orange optical tubes, the NexStar 4SE combines the classic heritage of the original orange tube telescopes with state-of-the-art features including a fully computerized operating system, flash upgradeable software, superior coatings, and Celestron's revolutionary SkyAlign telescope alignment software. SkyAlign is arguably one of the fastest and easiest go-to alignment methods available.

Once the NexStar 4SE is aligned, you are in the driver's seat. Simply choose an object from the menu and the telescope will find it for you. Using Celestron's patented NexStar technology, the SE scopes have the ability to locate nearly 40,000 objects. All you have to do is look through the eyepiece and enjoy the view!

But what if you are a beginner and don't know what object to choose? Not to worry - let the intelligent NexStar 4SE give you a guided tour of the night sky! The "Tour" feature offers a customized list of the best objects in the sky to view based upon the time, date and your location. Not only can your NexStar 4SE find objects, it can teach you about them as well. Information on the most popular objects can be viewed on the LCD screen of the keypad. (Note: Celestron literature refers to the keypad as a "hand control.")

Whether you are a seasoned astronomer looking for a portable scope with advanced features, or just starting your astronomy adventure and looking for an easy way to enjoy the night sky, a NexStar SE will help you take a closer look.

Celestron's Revolutionary SkyAlign

Using Celestron's patented SkyAlign, simply input the date and time, pick the nearest city to your location, then point the telescope at any three bright celestial objects. The on board NexStar computer does the rest, triangulating those three stars and mapping out a model of the night sky. You do not need to know the names of the alignment objects, and you can even pick the moon or bright planets. SkyAlign is fast, accurate, and above all, easy to use.
