The Bresser AC 70/400 AR-App Telescope Makes stargazing fun, easy and educational. Point it at the moon, planets or star clusters - and discover what's going on above your head.

Simple beginning, great journey of discovery!
This compact refractor is made for those just starting out in astronomy. With its 70 mm opening it captures enough light to provide bright and sharp images of the moon, Saturn's rings or Jupiter's moons. The focal length of 400 mm provides a wide field of view, so you quickly learn your way around the sky.
You get everything you need right away: two eyepieces and a 3x Barlow lens. This allows you to switch between low and high magnifications, up to 120x, depending on what you want to look at.
Explore the sky with Augmented Reality
The included AR app makes learning to watch easier than ever. Place your smartphone in the cradle, open the app and instantly see which constellation you are pointing to. The interactive display helps you understand the sky without complicated tables. You don't just learn to look - you understand what you see.

Daytime observations in natural perspective
This telescope is not just for the night. Thanks to the Amici prism you get an upright image - ideal for daytime nature observations. From distant mountains to birds on the horizon, you see everything in the right direction and with natural clarity.
And with the sunscreen included you can safely look at the sun. This allows you to see sunspots and structures without risk to your eyes.
Take pictures of your own discoveries
Simply attach your smartphone to the eyepiece mount and take your own photos of the moon or even the sun (with filter). Perfect for sharing with friends or family - your first step in astrophotography.
For beginners who want to start right away
The Bresser AC 70/400 AR-App is lightweight, easy to mount and ready to use immediately. No complicated settings, just point and watch. Within minutes you will experience your first real stargazing moment.
