OCULUM VERLAG - Fernrohr-Führerschein in 4 Schritten (GERMAN)

Unpack, set up, enjoy – with this complete telescope set you will soon begin your first exploration of the night sky. All the equipment for your new, exciting hobby is already included: the lens telescope with 70 mm aperture and 900 mm focal length, the equatorial mount, the tripod and a wide range of accessories for astronomical observations. Ideal for beginners: the system is very easy to handle and can even be used by children. Well-proven design for an easy beginning – the telescope With this set you'll start your voyage of discovery to the stars with a classic refracting telescope, a so-called achromatic refractor of the Fraunhofer type. The advantage of this particular design: even beginners as well as children can use it with ease. In addition, the Lyra refracting telescope impresses with good imaging properties due to its modern, precisely coated optics. If you compare this entry-level telescope to a corresponding astronomical telescope with a 60 mm aperture, you will notice: With its 70 mm aperture, the Lyra already collects 36 % more light. It also offers better resolution. In addition, 70 mm aperture and 900 mm focal length result in a very large focal ratio (ratio of aperture to focal length) of about 1 to 12.9 (F/12.9). The impressive result: a very sharp image with good contrast. Enjoy the view of our natural satellite, the Moon. Or take a look at the planets. Even the famous Pleiades sparkle captivatingly in your field of view. For the long focal length makes the telescope a specialist for observing the Moon, Sun, planets and open as well as globular clusters. And how big will these eye-catchers of the sky appear? Thanks to the 70 mm aperture, the resolution allows magnifications of up to 140x with really sharp images. Technically, much more would be possible – theoretically up to 675x using the included accessories. However, then the image sharpness could slowly decrease with increasing magnification. Of course – as with everything in astronomy – the prevailing conditions also play a role: So, how much you can actually magnify is determined not only by your telescope's performance but also by the air turbulence in the atmosphere (seeing conditions). Perfect foundation for your glimpse into space – mount and tripod Once you have found the ideal location for your astronomical telescope, you can quickly start exploring the sky. Simply mount the tube with the equatorial mount on the height-adjustable aluminium tripod. This special type of mount has the advantage of particularly convenient tracking: for this purpose, an axis is aligned parallel to the Earth's axis by pointing it approximately at Polaris during the so-called "alignment". Afterwards, the movement of the celestial bodies can be conveniently compensated for on this one axis rather than on both at the same time, as is the case with an azimuthal mount. In addition, the two flexible shafts with fine adjustment ensure the very precise and comfortable adjustment and tracking of the entry-level telescope. Always the right accessories at hand: the storage plate between the tripod legs provides space for eyepieces, barlow lens, solar filter etc.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! All-round equipment for astronomy newbies – the accessories Moon, planets or the Sun – with the extensive accessories you will get the best out of your astronomical telescope for any observation object. But initially, the LED viewfinder helps you find the nocturnal celestial bodies in the first place. To do this, the direction finder is installed and aligned parallel to the actual telescope. When you then look through it, a small red dot appears to hover in front of the sky. It shows you the spot at which the telescope is pointed. In this way, you precisely align the tube and easily find your objects before you gaze at them through the higher magnification of the telescope. Change of perspective for stargazers: using the two eyepieces you achieve different magnifications. They can be switched easily: With their standard socket diameter of 1.25 inches (31.7 mm), they are simply inserted into the eyepiece focuser of the entry-level telescope. Looking for even more detail? Then grab the 3x barlow lens and triple the magnification of the eyepieces. Comfortable observation at all times: a 90-degree star diagonal mirror is included. So, even if the telescope points vertically upwards into the sky, you can still look in comfortably from the side. For exciting discoveries during the day simply attach the safe solar filter to the telescope’s aperture. This way you can take a closer look at our own star and marvel at sunspots and granulation on the sun. CAUTION: Never point the telescope at the sun without the solar filter! Take the plunge into the fascinating world of astrophotography with the smartphone adapter. It allows you to use your smartphone as a camera on the telescope – and easily take exciting snapshots of your favourite celestial bodies such as the Moon or the Sun.

The view of the night sky holds countless fascinating sights in store for us. The BRESSER Polaris-I 102/460 EQ3 lens telescope comes with everything you need for a quick and easy start in astronomy: an astronomical lens telescope with 102 mm aperture and 460 mm focal length, an equatorial mount, a tripod and a wide range of accessories. The system is extremely easy to handle - perfect for newcomers to the exciting hobby of astronomy. Moreover, due to its compact dimensions, the entry-level telescope is ideally suited as a travel telescope. So find the perfect observation site and enjoy an exciting ''walk'' through the Milky Way. Classic telescope for a new generation of stargazers – the telescope Children and beginners in particular benefit from the classic design of this lens telescope, which is also called an achromatic refractor according to Fraunhofer. This is mainly due to its easy handling – ideal for your fist steps in celestial observation. The entry-level telescope owes its good imaging properties to the optics’ modern, precise coating. The 102 mm aperture already collects a lot of light from the celestial objects. But it is due to the very short focal ratio (ratio of 102 mm aperture and 460 mm focal length) of about 1 to 4.5 (F/4.5) that you can enjoy an extra-bright image. Another advantage of the combination of short focal length and fast focal ratio: the beginner's telescope shows you the details in the Milky Way and extended gas nebulae such as the North America Nebula NGC 7000 particularly impressively. This makes a ''trip'' through the Milky Way with low magnification so much fun. However, the telescope will also give you a lot of pleasure while travelling on Earth, because it is very compact and thus perfect as a travel telescope. And what about the magnification? Here, too, the aperture of 102 mm shows its effect: It gives the telescope a resolving power that easily allows magnifications of up to about 200x with sharp images. From a purely technical point of view, this is by no means the limit – with the included accessories, you can theoretically magnify up to 345x. The image sharpness can slowly decrease with increasing magnification, though. However, the degree of magnification achievable does not only depend on your telescope. The air turbulence in the atmosphere (seeing conditions) also influences your astronomical observations. Set up, align, start marvelling – mount and tripod Found the perfect location for your observations? Then attach the telescope tube to the eight-adjustable aluminium tripod with equatorial mount and off you go. The special advantage of equatorial mounts: Unlike with an azimuthal mount, you don't need to move both axes at the same time. Instead, you align one axis parallel to the Earth's axis by pointing it approximately at the polar star. Then you simply track the movement of the celestial bodies just on this one axis. Because you move the axes via two flexible shafts with fine adjustment, you can adjust and track the beginner's telescope very precisely and comfortably. And for quick access to all your accessories, simply place them on the tray between the tripod legs.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! Must-haves for star observation – the accessories In order for you to start stargazing right away, the astronomy set comes with many accessories. With the LED viewfinder, you can easily keep track of the sky. Just install the viewfinder parallel to the actual telescope and it projects a red dot onto a small ground-glass screen. When you look through it, this dot appears to be floating in front of the sky. Not just anywhere, but exactly at the point at which your telescope aperture is currently pointing. This allows you to align your telescope more precisely and find the celestial objects you have chosen for your night-time exploration much more easily. As with everything else, a change of perspective is always fun. Therefore, the two eyepieces (4 mm and 20 mm) allow you to view the objects in different magnifications – and thus enjoy completely different views. You want to see even more details? Then triple the magnification of the eyepieces with the 3x Barlow lens. The telescope for beginners is also flexible when it comes to upgrades: the diameter of the sockets is 31.7 mm (1.25 inches), which is an international standard that applies to all manufacturers. So you can choose from a large variety of additionally available eyepieces. In order for you to explore the universe with ease, the 90-degree star diagonal mirror always offers a comfortable view into the beginner’s telescope. Even if the telescope is pointed vertically upwards into the sky, you simply look in from the side – and just enjoy the view. But it is not only at night that the sky attracts our attention with spectacular highlights. In the daytime sky, our nearest star is particularly worth seeing. You can observe it completely safely using the solar filter. You will be amazed once you take a closer look at the sunspots and the granulation on the Sun. CAUTION: Never point the telescope at the Sun without the solar filter! Capture your favourite moments of sky observation. You can easily take your first steps in astrophotography by using the smartphone camera adapter – for impressive snapshots of the Sun and Moon, for example.
