Unleash the power of your smartphone and enjoy a guided tour of the night sky with no prior telescope experience required. The StarSense Explorer telescope uses award-winning, patent-pending StarSense sky recognition technology to analyse star patterns overhead and calculate its position in real time.

The StarSense Explorer app automatically generates a list of visible celestial objects, allowing you to view planets, brighter nebulae and galaxies, star clusters, and double stars from urban locations, or faint deep-sky objects from darker observing sites.

Easy Smartphone-Guided Navigation

The StarSense Explorer system simplifies locating celestial objects. Simply dock your phone, launch the StarSense Explorer app, and align it with the telescope’s optics using a quick two-minute setup. The app then displays arrows to guide telescope movement, and when the bullseye turns green, the object is ready to view in the eyepiece.

This approach removes the need for star charts, imprecise planetarium apps, or computerized mounts, delivering faster, easier, and more accurate object location.

Patent-Pending StarSense Sky Recognition Technology

StarSense Explorer determines where the telescope is pointed using patent-pending technology and a Lost in Space Algorithm (LISA), similar to those used by orbiting satellites. The app matches detected star patterns to its internal database, providing greater accuracy than apps relying solely on smartphone gyros and accelerometers and enabling precise confirmation when targets are visible in the eyepiece.

Optical Performance

The telescope features a 114mm (4.5”) Newtonian reflector with highly reflective coatings and strong light-gathering ability, delivering detailed views of key celestial objects including:

• Jupiter’s Galilean moons, cloud bands, and Great Red Spot

• Saturn’s rings

• The trapezium in the Orion Nebula

• The Pleaides Open Star Cluster

Mount & Handling

A manual altazimuth mount with altitude slow-motion adjustment and sliding rod allows smooth target tracking and precise positioning. The mount is supported by an adjustable, full-height tripod with accessory tray for organisation.

Smartphone Compatibility

StarSense Explorer supports most modern smartphones, including iPhone 6 and newer models and Android devices running version 7.1.2 or later manufactured since 2016.

City & Dark Sky Observing

Even in light-polluted environments, the telescope can identify and display Jupiter, Saturn, Venus, the Orion Nebula, double stars, and other prominent objects. In darker locations, additional targets such as the Andromeda Galaxy and Hercules Open Star Cluster become visible.

With a total kit weight of 10.4 pounds, the telescope is portable and suitable for camping trips or remote observing sites.
