Celestron STARSENSE EXPLORER™ LT 127AZ

Description

• 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, ExploreLeave 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 CompatibilityStarSense Explorer works with most modern smartphones, including iPhone 6 and up and most devices running Android 7.1.2 or later manufactured since 2016.

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 127mm (5”) objective mirror, 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 127mm (5″) Newtonian reflector under relatively dark skies, Omega Centauri, Tarantula Nebula, the Eta Carina Nebula and so many more southern sky jewels are easily within your reach.

  The entire telescope kit weighs just 5.2 kg, so it’s perfectly portable and easy to bring on your next camping trip or to a remote observing site. You don’t need mobile phone coverage to use the StarSense app, so it’s perfect for use in the bush.
