Celestron's NexStar 4SE Telescope: A Modern Take on a Classic Design

Celestron revitalizes their classic “orange tube” style with the NexStar 4SE, catering to both novice and seasoned stargazers. This telescope features a 4-inch aperture, blending excellent light-gathering capabilities with an affordable price. It provides stunning views of lunar and planetary surfaces, as well as deep-sky wonders like the Orion Nebula, all while maintaining a portable size.

The telescope's fully automated GoTo mount boasts a database of over 40,000 celestial objects, offering automatic tracking and locating capabilities. SkyAlign technology facilitates quick and easy telescope alignment, enabling even beginners to set up using any three bright objects in the sky.

The NexStar 4SE stands out with its unique single fork arm design and a robust steel tripod, both of which disassemble easily for convenient transport and quick setup. This telescope is an ideal first serious telescope, delivering remarkable views without breaking the bank.

Honoring a Legacy with Modern Innovations Celestron's legacy, dating back to the 1970s, began with their Schmidt-Cassegrain telescopes, making astronomy accessible and establishing Celestron as a leading telescope manufacturer. Tom Johnson, Celestron’s founder, pioneered the production of Schmidt corrector plates, balancing high-quality views with portability, and aimed to offer affordable optical instruments.

Today, the NexStar 4SE embodies these principles, enhancing the original design with contemporary features while adhering to Johnson's vision.

Explore the Wonders of the Cosmos The NexStar 4SE's primary mirror, measuring four inches, captures enough light to reveal the marvels of the solar system and beyond. Observe Saturn’s rings, Jupiter’s cloud bands, and lunar topography in detail. In darker skies, the telescope unveils deep-sky gems like the Hercules Globular Cluster and the Whirlpool Galaxy.

Innovative Single Fork Arm Mount for Easy Use The NexStar SE series features a unique, patented single fork arm mount, prioritizing portability and ease of setup. The telescope disassembles into lightweight, compact components, making it simple to transport and set up wherever you go.

The mount's sturdy construction ensures precise pointing and tracking, allowing you to easily follow celestial objects using the NexStar+ hand control, which includes a database of over 40,000 objects. SkyAlign technology simplifies alignment, and the optional StarSense AutoAlign offers even more convenience.

Expandable with Advanced Features The NexStar SE is designed to grow with your astronomical journey, compatible with various high-tech accessories. Enhance your experience with GPS coordination through SkySync or automatic alignment with StarSense AutoAlign. The built-in wedge supports long exposure tracking, perfect for lunar and planetary imaging, especially when paired with a NexImage camera. The NexStar 4SE is a telescope that evolves with your passion for astronomy.

Solar Warning	Never look directly at the Sun with the naked eye or with an optic (unless you have the proper solar filter). Permanent and irreversible eye damage may result. Never use your optic to project an image of the Sun onto any surface. Internal heat build-up can damage the optic and any accessories attached to it. Never leave your optic unsupervised. Make sure an adult who is familiar with the correct operating procedures is with your optic at all times, especially when children are present.
