National Geographic AC 70/400 AR-App Telescope

Explore the stars with your smartphone
The National Geographic AC 70/400 AR-App Telescope makes stargazing intuitive and fun. With a 70 mm aperture and a short focal length of 400 mm (f/5.7), you get a wide field of view in which you'll find the Moon, Saturn's rings and Jupiter's moons effortlessly. The lightweight tube and aluminum tripod are ready in minutes, so you can look right away.

Smart guidance via AR app
The included smartphone adapter and free AR app are the heart of this system. Place your phone on the cradle and point the telescope: the screen shows in real time which constellations and planets are in view. This is how you learn to navigate the night sky without complicated tables. The app also includes a mini-encyclopedia with explanations, stories and quizzes, ideal for young explorers.

Optics that show more
The 70 mm achromatic lens delivers bright, high-contrast images. The combination with the 45° Amici prism gives an upright image, useful for both astronomical and terrestrial observations. With the 3 included eyepieces (20 mm, 8 mm and 4 mm) and the 3× Barlow lens, you can easily vary between wide overview images and higher magnifications up to 140×.

Mobile observatory
Everything fits into the compact transport bag: telescope, tripod, eyepieces, prism, Barlow and smartphone holder. This makes it easy to take it with you to a dark spot outside the city. The low weight and easy handling make this scope ideal for children, families and beginners.

For added variety, a 3x Barlow lens is included that lets you triple the magnification. The smartphone adapter also lets you take your first astrophotos of the moon and planets. Everything fits into the included transport bag, so you can easily take this lightweight telescope with you to a dark spot outside the city.

What we recommend

With the National Geographic AC 70/400 AR-App Telescope, you see:

• Craters and mountains on the Moon
• Saturn's rings and Jupiter's largest moons
• Bright nebulae and star clusters such as the Orion Nebula and Pleiades
• Earthly objects such as landscapes or birds thanks to the Amici prism

This telescope is intended for educational, first-time discoveries. For detailed deep-sky photography or professional planetary imaging, a larger scope is better suited, but as an educational entry-level telescope with AR support, this model is unique.
