Celestron Starsense Explorer LT 127AZ Telescope
With the StarSense Explorer, Celestron has reinvented the manual telescope, as it is the first telescope to use your smartphone to analyze the night sky and calculate its position in real-time. The StarSense Explorer is ideal for beginners, thanks to the user-friendly app and detailed instructions. It's like having your personal guide to the night sky.
Place your phone, launch the app, explore the sky
With the StarSense Explorer, locating objects becomes easier, faster, and more accurate than ever. Within minutes of setting up the telescope, you will be navigating the sky with confidence. Simply place your smartphone in the special StarSense holder and launch the StarSense Explorer app. After aligning your phone with the telescope's optics, the StarSense Explorer creates a list of celestial objects that are visible at that moment. Select one, and arrows appear on the screen, guiding you on where to point the telescope. When the object is ready for observation, the reticle turns green.
Smartphone Compatibility
The StarSense Explorer works with most modern smartphones, including iPhones from the 6 and above, as well as most phones running Android 7.1.2 or later and manufactured after 2016.
StarSense Sky Recognition Technology – Patent Pending
The StarSense uses technology for which a patent application has been submitted and which, in collaboration with your mobile phone, accurately determines where your telescope is aiming in the night sky. A special algorithm, Lost in Space Algorithm (LISA), similar to those used by satellites in orbit to find their orientation, helps the application match star patterns it detects in the sky with its internal database.
There are other astronomy applications that claim they can help you find objects in the sky, but they rely solely on the phone's gyroscopes and accelerometers, which do not provide as much accuracy as LISA technology. No other application can accurately tell you when your target is within the field of view of your eyepiece.
Sturdy altazimuth mount
The simple altazimuth mount of the StarSense Explorer LT makes it easy to move the telescope to find the target. A fine height adjustment knob allows you to precisely correct the telescope's aiming and follow the target, which appears to shift in the sky (the apparent shift is actually due to the Earth's rotation around its axis). The entire system is mounted on an adjustable full-height tripod.
Stunning images with high-quality optics
With a primary mirror of 127mm (5”), this telescope has a sufficiently large light-gathering capacity to display details on the disks of the planets. You can expect bright and sharp images of Jupiter's four major moons, its cloud belts and the Great Red Spot, Saturn's rings, the trapezium in the Orion Nebula, and the beautiful open star cluster of the Pleiades.
Suitable for both city and dark skies
Even if you live in an urban area with intense light pollution, the StarSense Explorer is advanced enough to locate Jupiter, Saturn, Venus, the Orion Nebula, double stars, and a few more of the most well-known celestial objects.
But if you can transport the telescope to a darker location, more objects will be visible. With this 5-inch Newtonian telescope in a relatively dark location, you can easily see the Andromeda Galaxy, the open star cluster of Hercules, and many more.
The entire telescope package weighs just over 5 kg, so it is completely portable and you can very easily take it with you to a campsite or a distant observation location.
