Each eye is packed with light-sensitive cells called rhabdoms that are arranged in groups of eight. To date, they are still the only animal that can see these spiralling beams of light. Last year, scientists discovered that they can also see circularly polarised light, which travels in the shape of a helix. Think of attaching a piece of string to a wall and shaking it up and down, and you’ll get the idea. Previous studies have found that mantis shrimps can detect polarised light – light that vibrates in a single plane as it travels. If this biological design can be synthesised, it could form the basis of tomorrow’s multimedia players and hard drives. It contains a technology that’s very similar to that found in CD and DVD players, but it completely outclasses our man-made efforts. They can even see a special type of light – ‘circularly polarised light’ – that no other animal can.īut Nicholas Roberts from the University of Bristol has found a new twist to the mantis shrimp’s eye. While we see in three colours, they see in twelve, and they can tune individual light-sensitive cells depending on local light levels. Each eye can move independently and can focus on object with three different areas, giving the mantis shrimp “trinocular vision”. ![]() Take a particular attention to the safety instructions written in the user guide.The most incredible eyes in the animal world can be found under the sea, on the head of the mantis shrimps. Please, use only the batteries that are recommended. The batteries are not included in the delivery. Two 31.7 mm Kellner eyepieces (K-25mm, K-12.5mm).Automatically aligns with over 270,000 pre-programmed objects.In addition, you’ll also find a built-in compass for finding your bearings, as well as a moon filter that reduces the brightness and increases the contrast to produce stunning images of the moon.Įnjoy breathtaking views of the moon, planets, star clusters and other night sky objects – with the NATIONAL GEOGRAPHIC Automatic 90 mm telescope. A star chart is also included with the set, which shows you what you can see in the night sky from your current location. For example, the LED finder scope gives you an overview of the night sky and makes it easier to find objects for initial alignment – a small red dot shows you the area at which the telescope is currently pointing. Once you’ve assembled everything, you can make use of the extensive accessories to help you get started with your night sky observations. And if you need to travel light, you can leave the steel tripod at home, as the GoTo telescope can also be used on a sturdy table or other level surface.įeature-packed astronomy kit with practical accessories Thanks to its compact Cassegrain design, this telescope is easy to transport to your favourite stargazing spots. The best places for stargazing are rarely next to your front door – to see as much as possible, you’ll need to find a dark place with an unobstructed view of the sky. Practical GoTo telescope for on-the-go use The entry-level telescope also has a 90 mm aperture, which collects around 165 times more light than the human eye, allowing you to explore deep sky objects such as the M27 Dumbbell Nebula in the constellation of Vulpecula or the M57 Ring Nebula in the constellation of Lyra. Thanks to the two included eyepieces, you can choose between 50x and 100x magnification. Marvel at Jupiter’s clouds or Saturn’s rings – featuring a 1250 mm focal length, this astronomical telescope is perfect for taking a closer look at the large planets in our solar system. ![]() Choose from an amazing range of night sky objects and explore the wonders of the universe!įeature-packed telescope for beginner astronomers What’s more, the telescope tracks objects automatically via its two quiet motors in order to compensate for the earth’s rotation. From fascinating gas giants to bright deep-sky objects, you can use the practical handset to bring your target into view with a few simple button presses. It comes with an altazimuth GoTo mount, which allows you to align the telescope automatically with over 270,000 pre-programmed night sky objects. The NATIONAL GEOGRAPHIC Automatic 90 mm telescope is the perfect entry-level telescope for beginner astronomers.
