Celestron StarSense Explorer™ DX 5" Smartphone App-Enabled SCT

StarSense Explorer: Smartphone Navigation with 2-Minute Alignment

Celestron's patented StarSense sky recognition technology transforms your smartphone into a real-time planetarium and targeting system. Simply dock your phone, launch the app, and complete a quick 2-minute alignment. The app uses a Lost in Space Algorithm (LISA) to analyze star patterns overhead, calculating the telescope's exact position with far greater accuracy than apps that rely solely on a phone's internal gyros. On-screen arrows guide your movements, and a green bullseye confirms when your target is perfectly framed in the eyepiece.

125mm f/10 Schmidt-Cassegrain: 329x Light Gathering with XLT Coatings

At the heart of the StarSense Explorer DX 5" is a high-quality 125mm (5") Schmidt-Cassegrain optical tube, a design proven for over 50 years. This aperture provides a light gathering power of 329x compared to the naked eye, reaching a limiting stellar magnitude of 13. The f/10 focal ratio is ideal for high-magnification views of the Moon and planets, allowing you to resolve Jupiter's cloud bands, the Cassini Division in Saturn's rings, and tiny lunar craters.

• StarBright XLT Coatings: All air-to-glass surfaces are treated with Celestron's premium optical coatings, maximizing light transmission and contrast for brighter, sharper views of everything from faint galaxies to subtle planetary details.
• Included Magnification: The package includes a 25mm eyepiece for a wide 50x view, perfect for locating objects, and a 10mm eyepiece that boosts the power to 125x for close-up observations.
• Compact Power: Despite its 1250mm focal length, the optical tube is only 330mm (13") long and weighs just 5 lbs, making it incredibly portable.

Alt-Azimuth Mount: Stable Manual Pointing with Slow-Motion Controls

The StarSense Explorer app is paired with a sturdy, manual alt-azimuth mount designed for stability and precision. The full-height tripod features 31.75mm (1.25") steel legs, providing a solid foundation that minimizes vibrations. While you move the telescope manually to get close to your target, the dual-axis slow-motion control knobs allow for fine, deliberate adjustments, making it easy to center objects or track them smoothly as they drift across the sky.

StarSense DX 5" vs. NexStar 5SE: App-Assisted Manual vs. Full GoTo

Both the StarSense Explorer DX 5" and the NexStar 5SE feature the same excellent 125mm f/10 XLT-coated Schmidt-Cassegrain optics, but they offer two different philosophies for exploring the night sky.

• NexStar 5SE Advantage: The primary advantage of the NexStar 5SE is its fully computerized GoTo mount. It automatically locates and tracks any of the 40,000+ objects in its database, which is ideal for observers who want push-button convenience or plan to do planetary imaging.
• StarSense Explorer DX 5" Advantage: The StarSense Explorer operates without any external power, making it more portable and field-ready. Its app-guided, hands-on approach teaches you the sky as you observe, offering a more engaging experience. It achieves precise pointing without the cost and complexity of a GoTo system.
