With the StarSense Explorer app and your phone mounted in the custom dock, this scope becomes your personal tour guide to the cosmos.
And this isnt just any telescope slapped onto a phone dockits a high-performance 5″ (127mm) Schmidt-Cassegrain optical tube coated with Celestrons legendary StarBright XLT multi-coatings. Whether youre scanning Saturns rings, hunting down the Hercules Cluster, or enjoying the crisp lunar terminator, the StarSense Explorer DX 5″ SCT has the optics and guidance system to make your observing time count.
Key Features
StarSense Explorer: Smartphone Navigation Meets Telescope Precision
The magic starts with Celestrons patented StarSense sky recognition technology. It uses your smartphones camera, not its internal gyros or accelerometers, to image the sky and determine the telescopes orientation in real time. This Lost in Space Algorithm (LISA) is the same type of tech used by satellites, and its far more accurate than apps relying on your phones sensors.
Once you dock your phone and align it with the telescope, the StarSense Explorer app automatically generates a list of visible objects and guides you to them with on-screen arrows. Follow them with the slow-motion controls, and when the target is centered, the bullseye turns greenits in the eyepiece.
5-Inch Schmidt-Cassegrain Optics
With a 5″ aperture (127mm) and 1250mm focal length (f/10), this scope brings plenty of light-gathering ability in a compact package. The Schmidt-Cassegrain design is a favorite for a reasonits versatile, portable, and delivers high-contrast, sharp images across a wide range of magnifications. StarBright XLT coatings further improve brightness and contrast, whether you’re viewing Saturns Cassini Division or teasing out the spiral arms of the Whirlpool Galaxy from darker skies.
Manual Alt-Az Mount with Fine Control
The DX alt-azimuth mount provides buttery-smooth movement with geared slow-motion controls on both axes. Slip clutches make it easy to move the telescope manually, then switch to fine tracking as your target drifts. You get the hands-on feel of a manual mount without the frustration, ideal for beginners or those looking for a quick grab-and-go setup.

Observing Tip
For best performance, take the StarSense Explorer DX 5″ SCT out of the city. While it does perform well under urban skiesresolving double stars, showing planetary detail, and revealing brighter deep-sky objectsthis scope truly shines when it gets a taste of darker skies. Bring it along on your next camping trip or drive a few miles outside city limits and watch the Andromeda Galaxy bloom into view.
