The magnification of your telescope can be trippled with the use of this achromatic BRESSER Barlow Lens 3x 31.7 mm (1.25'').

Open the case and you're ready to go: The BRESSER Arcturus 60/700 AZ lens telescope shows you the fascinating world of star clusters and planets. This complete set contains everything you need for your first steps into sky observation: an astronomical lens telescope with 60 mm aperture and 700 mm focal length, an azimuthal mount, a tripod and lots of accessories. The system is very easy to handle and therefore ideal for introducing children to astronomy as a hobby. And since there are so many beautiful things to discover on Earth as well, the telescope is suitable for observing nature and landscapes. Simply an astro-classic – the telescope With this classic lens telescope – a so-called Fraunhofer achromatic refractor – even beginners and children can easily gain new insights into the night sky. Thanks to the modern, precisely coated optics, the starter telescope offers good imaging properties. A sharp image with good contrast – this is ensured by the large focal ratio of about 1 to 11.7 (F/11.7), which results from the ratio of the 60 mm aperture to the 700 mm focal length. Perfect for exploring our Moon, the planets, but also open star clusters and globular clusters. And what about the magnification? The 60 mm aperture provides a resolving power that easily allows magnifications up to about 120x with really sharp images. Technically, even more is possible with this beginner’s telescope – up to 175x with the included accessories. However, as the magnification increases, the image can become more and more blurred. How much magnification is actually possible depends not only on the telescope, but also on the air turbulence in the atmosphere (seeing conditions). The foundation for moving impressions – mount and tripod For your nighttime observations, attach your telescope to the height-adjustable aluminium tripod with azimuthal mount. Thanks to its extremely easy operation, you can enjoy effortless astronomical explorations with this azimuthal mount. Just like with a normal photo tripod, you simply turn the starter telescope by hand up and down, to the left and right. To ensure that your eyepieces, compass, star map etc. are always within reach, simply place your accessories on the practical storage plate located between the tripod legs. Everything for a good start in astronomy – the accessories In the sturdy hard-top case, in which you can store the beginner's telescope perfectly and take it safely with you on your travels, you will also find lots of accessories. The 5x24 finder is a small miniature telescope that you simply mount parallel to the actual telescope. With its weak 5x magnification and integrated crosshair, it helps you keep track of the starry sky. So it allows you to easily find celestial objects and precisely align the telescope – before you then enjoy the view with the higher magnification. And how high the magnification is depends on which of the three included eyepieces (4 mm; 12.5 mm; 20 mm) you are currently using. To change the magnification, simply insert another one into the telescope's focuser. If at some point you want to change your field of view with additional eyepieces: no problem! The 1.25 inch (31.7 mm) socket diameter complies with an international and cross-manufacturer standard, so you can combine a wide range of optional eyepieces with your telescope. For a comfortable view at any time, you will also find a 90-degree diagonal mirror in the scope of delivery. Otherwise, you would have to lie down under the starter telescope in order to achieve good observation results when the optics are pointed upwards into the sky. Instead, you simply look in comfortably from the side. In addition to the night sky, the Earth also offers many captivating sights. That's why the 1.5x erecting lens turns the image the right side around, so that you can devote your entry-level telescope to observing nature and landscapes during day. However, because orientation in the night sky is not as easy as on our daytime planet, a compass and star map are included in the set. This way you always know where to look and what you will see there. Enjoy a quick start to the exciting hobby of astronomy with the BRESSER Arcturus 60/700 AZ lens telescope including all accessories.

Embark on a voyage of discovery through our solar system and beyond using the BRESSER Spica-II reflector telescope. You can start straight away with your new hobby, because this complete astronomy set already comes with everything you need for exciting observations: an astronomical reflector telescope with 130 mm aperture and 1000 mm focal length, an equatorial mount, a tripod and extensive accessories. Perfect for the astro-novice: the system is very easy to use. So look forward to fascinating sights especially of the Moon, the planets and the Sun. Perfect combination of mirror and lens – the telescope Using the Spica-II you’ll start your celestial exploration tour with a classic reflecting telescope of the "Newton" type with an additional lens inside the focuser. This combination of mirror and lens is called "catadioptric". It’s immediately noticeable with this type of telescope that you do not look in at the back, but at the front and laterally. What is the advantage? Even if the telescope is pointed vertically into the sky, you can observe the beauties of the night sky in a comfortable posture. In addition, catadioptric telescopes impress with their transportability, because despite the long focal length, the tube is comparatively short. With its 130 mm aperture, the Spica-II already collects a lot of light from celestial objects. In addition, 130 mm aperture and 1000 mm focal length result in a focal ratio (ratio of aperture to focal length) of 1 to 7.7 (F/7.7). This means you can enjoy an image with good contrast even at high magnifications. Thus, the telescope is well suited for observing the planets and details on the Moon. Even some deep sky objects are worth looking at through this entry-level telescope: admire open star clusters and globular clusters as well as bright so-called planetary nebulae such as the Ring Nebula M57 in the constellation Lyra. And how big will the nocturnal highlights appear? The 130 mm aperture achieves a resolution that allows magnifications of up to about 260x with sharp images. Technically, even more is possible – theoretically up to 750x with the included accessories. However, as the magnification increases, the sharpness of the image may slowly decrease. In addition, as is so often the case in astronomy, you are also dependent on the prevailing conditions. For example, the air turbulence in the atmosphere (seeing conditions) always plays a role in your magnification possibilities. Note for nature lovers: If you choose a Newtonian telescope like the Spica-II reflector telescope, you can look forward to a specialist in astronomical observation. However, the image is always displayed laterally reversed as well as upside down, which makes no difference when observing the sky. However, this type of telescope is less suitable for nature and landscape observation during the day. Would you like to use your new telescope for exciting nature discoveries as well? Then we recommend that you choose one of the BRESSER refractor telescopes. A good foundation for your astro-start – mount and tripod If you want to look up at the sky, you need a solid base on the ground. That's why you will find a robust height-adjustable aluminium tripod and an equatorial mount in your telescope set. The special advantage of this type of mount: unlike an azimuthal model, the movement of the celestial bodies is compensated for only on one axis instead of two. For this purpose, one axis of the equatorial mount is aligned parallel to the Earth's axis in the course of the so-called "alignment". This is easily done by pointing it approximately at Polaris. Perfect for convenient adjustment and tracking of the entry-level telescope: the axes can be moved precisely via the two flexible shafts with fine adjustment. And if you simply place smartphone adapter, eyepieces etc. on the convenient storage plate between the tripod legs, you will have the equipment you need quickly at hand.Keep track of things automatically: For this telescope’s equatorial EQ-3 mount, the tracking motor with item number 4951400 is available as an optional accessory. This eliminates the need to manually track a celestial object set in the telescope. When this motor is installed at the mount, it automatically tracks the celestial object, keeping it in the field of view of the eyepiece. This makes observing the night sky even more comfortable! Everything for the astro-beginner – the accessoriesFor your start into the wonderful world of astronomy, the Spica-II beginner's telescope comes with lots of accessories. The LED viewfinder, for example, is great for orientation in the night sky. You simply install the direction finder parallel to the actual telescope. It projects a red dot onto a small ground-glass screen that appears to float in front of the sky when you look through it. In this way, it shows you where the telescope is pointing. A great help for the exact alignment of the telescope and the easy location of celestial objects before you gaze at them with higher magnifications. You determine how detailed you observe your discoveries by using one of the two eyepieces, each of which provides a different magnification. They are fitted with standard 1.25-inch (31.7 mm) diameter sockets which allow them to be easily inserted into the eyepiece focuser of the entry-level telescope. Would you like to look even closer? Then grab the 3x barlow lens, which triples the magnification of the eyepieces in no time. Explore the astronomical highlight of the daytime sky: With the safe solar filter you can examine sunspots as well as granulation on the Sun. CAUTION: Never point the telescope at the Sun without the solar filter! There is also a suitable accessory for your first steps in astrophotography: with the smartphone adapter, you can use your mobile phone as a camera on the telescope. First snapshots of the Moon or Sun made easy! FEATURES Reflector telescope with 130 mm aperture and 1000 mm focal length Reflector type catadioptric Well suited for observing the Sun, Moon and planets Height-adjustable tripod with equatorial EQ3 mount Precise adjustment through flexible shafts and fine adjustment in both axes Easy to use, very good for beginners Focal ratio F/7.7, therefore good for observing the planets and details on the Moon 1.25-inch focuser (31.7 mm) Two eyepieces and one barlow lens with 1.25-inch (31.7 mm) sockets for different magnifications Safe solar observation with the included solar filter First steps in astrophotography with smartphone camera adapter SCOPE OF DELIVERY Telescope Aluminium tripod Equatorial EQ3 mount Eyepieces: 4 mm and 20 mm (1.25-inch sockets) Barlow lens 3x (1.25-inch socket) LED illuminated viewfinder Solar filter Smartphone camera adapter Accessory tray Astronomy software as download Instruction manual
