Celestron StarSense Explorer LT70AZ Telescope

Celestron StarSense Explorer LT70AZ Telescope

The StarSense Explorer LT70AZ is a 70 mm refractor telescope that uses a smartphone to identify objects in the night sky and calculate the telescope’s orientation in real time. The app’s guidance and tutorials are particularly well suited to beginners who want to find planets, nebulae and double stars without the need for star charts.

Your smartphone will guide you to your destination

The phone is placed in the StarSense dock, and it is aligned with the telescope’s optics in around two minutes. The StarSense Explorer app then displays a list of currently visible objects, and arrows on the screen guide you to point the telescope in the right direction. When the object is visible through the eyepiece, the crosshairs turn green. The patented Lost in Space algorithm (LISA) compares the constellations observed in the sky with the app’s database, so positioning is not based solely on the phone’s gyroscopes and accelerometers.

Crisp vision by day and by night

Fully coated glass optics improve light transmission and bring out the fine details of celestial objects. Even in a city with light pollution, you’ll be able to spot Jupiter, Saturn, Venus, the Orion Nebula and double stars, whilst in darker areas even more objects will become visible. The included 90-degree angle mirror also allows you to observe birds, wildlife and landscapes during the day.

Altitude adjustment base and fine adjustment

With the alt-azimuth mount, it is easy to swivel the telescope from one object to another, and the slow-motion elevation adjustment helps you track objects moving across the sky. The whole assembly is mounted on an adjustable, full-height tripod, and the entire set weighs just 4.2 kg, making it easy to take along on excursions and to observation sites.

Main features

• StarSense Sky Recognition technology uses the smartphone’s camera to locate the point in the sky that the telescope is pointing at.
• The app lists the visible locations and navigates to them using the arrows on the screen.
• Two eyepieces and a 2x Barlow lens provide a total of four different magnifications.
• With the StarPointer red-dot finder, you can align the telescope even without an app.
• Thanks to the corner mirror, the device can be used during the day for observing nature and landscapes.
• The accessory tray keeps eyepieces and accessories organised during observations.
