Omegon AC 70/400 Solar BackPack AZ Refractor Telescope
The Omegon AC 70/400 Solar BackPack AZ is a compact and lightweight refractor telescope designed for travellers, beginners, and anyone who wants a capable optical instrument that is always ready to go. Weighing just 1.5 kg, this telescope packs impressive performance into a surprisingly small package - making it an ideal companion for hikes, holidays, or spontaneous stargazing sessions away from the city.
Optics and Performance
The telescope uses a classic achromatic refractor design with a 70 mm aperture and a focal length of 400 mm, giving a focal ratio of f/5.7. All optical components are made exclusively from glass - not plastic - which ensures clear, sharp, and high-contrast images both on the sky and on the ground. The achromatic objective lens corrects chromatic aberration, producing bright and well-defined views across the field.
The set includes two 1.25" eyepieces: a 20 mm eyepiece delivering 20x magnification and a 10 mm eyepiece delivering 40x magnification. These two magnifications cover a wide range of practical uses - from sweeping wide fields of star clusters and the Milky Way to taking a closer look at the lunar surface or distant terrestrial objects. The maximum usable magnification of the telescope reaches 168x, giving room to grow as your observing experience develops.
Solar Observation
A dedicated solar filter is included in the package, making the Omegon AC 70/400 Solar BackPack one of the few entry-level telescopes genuinely ready for safe solar observation right out of the box. With this filter you can observe sunspots and the subtle granulation of the solar disc with your own eyes - a remarkable and often underestimated aspect of amateur astronomy that is possible even in daylight hours.
Mount and Tripod
The telescope is mounted on an altazimuth (AZ) mount with adjustable tension controls on both axes, allowing smooth and precise pointing in any direction. The slow-motion controls let you track objects without overcorrecting - particularly useful when observing the Moon or Sun at higher magnification. The mount attaches to an included aluminium tripod, which features a universal camera/camcorder attachment bracket so it can double as a photo tripod when needed.
Assembly requires no tools and takes only a few minutes, making this telescope genuinely practical for use in the field. There are no complex procedures to follow before you can start observing.
Ready to Go - Everything in One Backpack
The entire set - telescope tube, mount, tripod, eyepieces, and solar filter - fits into the included branded backpack. This means you can pack the telescope in the same bag as your other travel essentials and carry it comfortably wherever you go. The backpack transforms what might otherwise be an awkward collection of equipment into a single, easy-to-transport unit.
What Can You Observe?
Despite its compact size, the Omegon AC 70/400 Solar BackPack delivers a genuine astronomical experience. With 70 mm of aperture you can explore the craters and mountain ranges of the Moon in fine detail, observe the phases of Venus, see Jupiter's four Galilean moons and the planet's main cloud bands, catch Saturn's iconic rings, and resolve dozens of open star clusters and bright nebulae in the night sky. On the ground it performs equally well as a spotting scope for birdwatching, landscape observation, or watching distant sporting events.
