Celestron NexStar 4SE Maksutov Computerised Telescope
Celestron’s NexStar 4SE telescope combines advanced features and excellent optics in one easy-to-use system. It’s the perfect choice for your first serious telescope, offering striking views of the night sky, planets and the Moon.
Anyone who enjoys stargazing or moon gazing can delight in observing the starry night sky. The 4SE’s four-inch primary mirror packs enough light-gathering ability to observe the best that the solar system has to offer: Saturn’s rings, the cloud bands on Jupiter, and geographic features on the surface of the Moon. When it comes to deep sky objects, take your 4SE to a dark-sky site and you’ll see hundreds of pinpoint stars in the Hercules Globular Cluster, the spiral arms of the Whirlpool Galaxy, and more. This is a great telescope for any fan of astronomy.
• 4-inch aperture provides excellent light-gathering ability. You’ll get impressive views of the Moon and planets, along with deep sky objects like the Orion Nebula, while retaining a compact form factor.
• Fully automated GoTo mount with database of 40,000+ celestial objects automatically locates and tracks objects for you.
• SkyAlign technology gets your telescope aligned and ready to observe in minutes. Even if you’re unfamiliar with the night sky, you can easily align your telescope on any three bright objects.
• Unique single fork arm design and sturdy steel tripod all break down into separate components for easy transport and quick assembly. You’ll have no problem getting the NexStar SE to your favourite observing site, or setting it up quickly in your garden.
