Celestron has reinvented the manual telescope with StarSense
Explorer—the first telescope that uses your smartphone to analyze the
night sky and calculate its position in real time. StarSense Explorer is
ideal for beginners thanks to the app’s user-friendly interface and
detailed tutorials. It’s like having your own personal tour guide of the
night sky.
Dock, Launch, Explore
Leave complicated star charts, imprecise planetarium apps, and
computerized mounts behind. With StarSense Explorer, locating objects
has never been easier, faster, or more accurate. Within minutes of
setting up the telescope, you’ll be navigating the sky with confidence.
Simply place your phone in the unique StarSense dock and launch the
StarSense Explorer app. After aligning your phone to the telescope’s
optics (a quick, 2-minute procedure), StarSense Explorer generates a
list of celestial objects currently visible. Make your selection and
arrows appear onscreen, guiding you as you to move the telescope. When
the object is ready to view, the bullseye turns green.
Smartphone Compatibility
StarSense Explorer works with most modern smartphones, including
iPhone 6 and up and most devices running Android 7.1.2 or later
manufactured since 2016. For a complete compatibility list, click here.
Patented StarSense Sky Recognition Technology
StarSense Explorer uses patented technology and your smartphone to
determine exactly where the telescope is pointed in the night sky. A
Lost in Space Algorithm (LISA), like the ones satellites use in orbit to
correctly orient themselves, helps the app match star patterns it
detects overhead to its internal database.
While other astronomy apps may claim that they can help you find
objects, they rely exclusively on the phone’s gyros and accelerometers,
which aren’t as accurate as LISA technology. No other app can accurately
tell you when your target is visible in the eyepiece.
High Quality Altazimuth Mount with Slow Motion Control
An ultra-stable altazimuth mount provides a sturdy foundation for
StarSense Explorer DX. Slip clutches and geared slow motion controls in
both axes help you move the telescope smoothly and zero in your target.
As celestial objects appear to drift across the night sky, you’ll be
able to follow them with just a few turns of the knobs. It’s all
anchored by an adjustable, full-height tripod.
Dazzling Views with High Quality Optics
With a large 5” Schmidt-Cassegrain optical tube—Celestron’s
tried-and-true optical design for over 50 years—this telescope has
enough light gathering ability to bring out impressive detail in
celestial objects while remaining compact and lightweight. You can
expect sharp, bright views of Jupiter’s four Galilean moons, its cloud
bands and Great Red Spot, the rings of Saturn, the trapezium in the
Orion Nebula, and the beautiful Pleiades Open Star Cluster.
All air-to-glass surfaces are coated with our StarBright XLT optical
coatings to visibly increase contrast and light transmission for
brighter deep space views. With StarBright XLT, you’ll be able to
discern subtle details while viewing the Moon and planets as well as
faint galaxies and nebulae. For more information about our patented
StarBright XLT coatings, visit here.
Perfect for the City or Dark Sky Sites
Even if you live in a light polluted city location, StarSense
Explorer is advanced enough to be able to pick out Jupiter, Saturn,
Venus, the Orion Nebula, double stars, and a few more of the most famous
celestial objects.
But if you can take the telescope to an even slightly darker
location, more objects will become visible. With this 5”
Schmidt-Cassegrain and relatively dark skies, the Andromeda Galaxy,
Hercules Open Star Cluster, and so many more are easily within your
reach.

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.
