A Compact Powerhouse for Star Gazers


The Celestron NexStar 4 SE Telescope is a compact, powerful, and versatile telescope designed for both beginners and experienced astronomers. This comprehensive review will cover the key features, performance, ease of use, and value for money that the NexStar 4 SE offers.

Celestron has a long history of producing high-quality telescopes, and this model is no exception.

Overview of the Celestron NexStar 4 SE

The NexStar 4 SE is a Maksutov-Cassegrain telescope with a 102mm (4-inch) aperture, a 1325mm focal length, and an f/13 focal ratio. This telescope sits on Celestron's well-regarded computerized SE mount with an integrated single-arm fork design. The package also includes an eyepiece, a red dot finder scope, a tripod with an accessory tray, and the NexStar+ hand controller.

Key Features

Optical Performance

The Celestron NexStar 4 SE boasts excellent optical performance for its size, thanks to its Maksutov-Cassegrain design. The 4-inch aperture gathers a good amount of light, allowing for clear and detailed views of the Moon, planets, and brighter deep-sky objects. The f/13 focal ratio, while making the telescope less suitable for wide-field views, provides high-contrast, high-resolution images that are perfect for planetary and lunar observation. The StarBright XLT coatings on the optics enhance light transmission and minimize reflections, further improving image quality.

Computerized SE Mount and NexStar+ Hand Controller

The NexStar 4 SE's computerized SE mount is a significant feature that adds to its appeal. The mount is equipped with dual-axis motors, allowing for precise tracking and smooth movement across the sky. The included NexStar+ hand controller features a database of over 40,000 celestial objects, enabling users to easily locate and observe a vast array of celestial wonders. The controller also includes features like guided tours, custom object lists, and multiple alignment procedures.

Portability and Ease of Use

One of the most attractive features of the Celestron NexStar 4 SE is its compact size and portability. The telescope's tube and mount weigh a combined 11 pounds, making it easy to transport and set up. The included tripod is sturdy, yet lightweight, and the accessory tray provides convenient storage for eyepieces and other accessories. Additionally, the telescope's single-arm fork design allows for quick and easy setup, and the NexStar+ hand controller's intuitive interface makes navigating the night sky a breeze.

Expandability and Compatibility

The Celestron NexStar 4 SE is compatible with a wide range of accessories, including additional eyepieces, Barlow lenses, filters, and cameras for astrophotography. The telescope's 1.25-inch eyepiece holder and T-adapter make it easy to switch between different eyepieces or attach a camera for astrophotography. The built-in wedge on the tripod allows for basic equatorial tracking, enabling long-exposure photography with the addition of an optional motor drive.


The NexStar 4 SE's performance is impressive for its size. The 4-inch aperture provides bright, clear images of the Moon, revealing craters, mountains, and other lunar features in exquisite detail. Planetary views are equally striking, with Jupiter's cloud bands and Great Red Spot, Saturn's rings, and the largest moon, Titan, all clearly visible. The telescope also performs well on brighter deep-sky objects, such as the Orion Nebula, and Andromeda Galaxy, and star clusters like the Pleiades and the Hercules Globular Cluster. The high-resolution images are perfect for discerning fine details on planetary and lunar surfaces, making it an excellent choice for observers who prioritize planetary observation.

Astrophotography Potential.

While the NexStar 4 SE is not specifically designed for astrophotography, it is still possible to capture some impressive images of the Moon and planets with the right accessories. The built-in wedge and motor drive allow for basic equatorial tracking, which can enable long-exposure photography for capturing some deep-sky objects. However, it is worth noting that the f/13 focal ratio and the mount's tracking capabilities may not be suitable for serious deep-sky astrophotography. For those primarily interested in astrophotography, a larger-aperture telescope with a more robust equatorial mount may be a better option.

Value for Money

The Celestron NexStar 4 SE offers a great balance of performance, portability, and features at a competitive price point. While there are less expensive telescopes on the market, the NexStar 4 SE provides a level of quality and functionality that is hard to beat at this price range. The computerized SE mount, with its extensive database and user-friendly interface, is a standout feature that greatly enhances the overall stargazing experience. Additionally, the telescope's compatibility with a wide range of accessories allows users to expand and customize their setup as their interests and skills grow.
