Product Highlights Unleash the power of your smartphone to take you on a guided tour of the night sky—no telescope experience required. Patent-pending StarSense sky recognition technology uses your
smartphone to analyze star patterns overhead and calculate its position
in real time. StarSense Explorer app automatically generates a list of objects
currently visible. View planets, brighter nebulae and galaxies, star
clusters, and double stars from the city. Or take your telescope to
darker skies to view faint, deep sky objects. Manual altazimuth mount with smooth, dual-axis slow-motion controls
makes it easy to follow the on-screen arrows to your desired target.
When the bullseye turns green, it’s ready to view in the telescope’s
eyepiece. 130mm (5”) Newtonian reflector with highly reflective coatings and
enough light gathering ability to view all the best celestial objects. Includes 25mm and 10mm eyepieces, StarSense smartphone dock, a red
dot finderscope (in case you want to use the telescope without your
phone), and a sturdy, full-height tripod. 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 .
Patent-Pending StarSense Sky Recognition Technology
StarSense Explorer uses patent-pending 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 reorient 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 turn of the knobs. It’s all anchored by
an adjustable, full-height tripod.
Dazzling Views with High Quality Optics
With a large 130mm (5”) objective lens, this telescope has
enough light gathering ability to bring out impressive detail in
celestial objects. 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 beautiful Pleaides Open Star
Cluster. Highly reflective coatings on both the primary and secondary
mirror enhance the views even more.
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” Newtonian and
relatively dark skies, the Andromeda Galaxy, Hercules Open Star Cluster,
and so many more are easily within your reach.
The entire telescope kit weighs just 18 pounds, so it’s perfectly
portable and easy to bring on your next camping trip or to a remote
observing site.
