With a 70 mm aperture and a 400 mm focal length, it delivers sharp and clear views of the Moon, planets, and distant star clusters. Everything you need to get started right away is included in the box: three eyepieces, a star diagonal mirror, a 1.5x erecting lens, a 5x24 finder scope, and a smartphone adapter. All your gear can be conveniently stored and carried in a stylish, sturdy backpack featuring the Astro and BRESSER FAMILY design - simply pack up and head out to meet the stars.
Designed for Young Astronomers
The telescope is designed to be lightweight, compact, and easy to use even for the youngest observers. The altazimuth (AZ) mount allows smooth movement of the tube in all directions - up, down, left, and right - with no complicated adjustments required. Use the 5x24 finder scope to quickly point at your target object, then explore it in detail with your chosen eyepiece.
Magnification and Optics
The three included eyepieces provide magnifications of 20x, 33x, and 66x, letting you examine the cratered surface of the Moon, planets of the solar system, and distant star clusters such as the Pleiades or the Orion Nebula. Add the 1.5x erecting lens and the magnification increases to 30x, 50x, and 100x - making lunar details truly stunning. The star diagonal mirror allows comfortable viewing even when the telescope is pointed nearly straight up, eliminating awkward neck bends.
