Celestrons signature orange-tube telescope combines advanced features and excellent optics in one easy-to-use system, the NeXStar 5SE. Its the perfect choice for your first serious telescope, offering striking views at an economical price. In the 1970s, Celestrons Schmidt-Cassegrain telescopes brought the hobby of astronomy to the masses and established Celestron as the worlds premier telescope maker. Our founder, Tom Johnson, invented Celestrons proprietary method of producing Schmidt corrector plates for superior views and maximum portability. Johnson believed in creating high-quality optical instruments at an affordable price, and inspired a generation of amateur astronomers. Four decades later, we've improved upon this design by adding cutting-edge features, while staying true to our founders intent.
