BRESSER Polaris-I 102/460 EQ3 Refractor Telescope with Smartphone Adapter & Solar Filter
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. Set off on your very own voyage of discovery to the Sun, Moon and through the Milky Way – with the BRESSER Polaris-I 102/460 EQ3 refractor telescope. FEATURES Telescope for beginners with 102 mm aperture and 460 mm focal length Achromatic refractor type Fraunhofer Ideal for observing the Milky Way and extended gas nebulae at low magnifications Height-adjustable tripod with equatorial EQ3 mount Easy to use, very good for beginners Focal ratio F/4.5, therefore very fast and bright image Very compact, therefore good as a travel telescope 50.8 mm (2 inch) focuser with adapter to 31.7 mm (1.25 inch) Two eyepieces and one Barlow lens with 31.7 mm (1.25 inch) sockets for different magnifications Safe solar observation with the included solar filter Entry into astrophotography with smartphone camera adapter SCOPE OF DELIVERY Lens telescope Aluminium tripod Equatorial EQ3 mount Eyepieces: 4 mm and 20 mm (1.25 inch sockets) Barlow lens 3x (1.25 inch socket) Star diagonal mirror LED illuminated dot finder Solar filter Smartphone camera adapter Accessory tray Astronomy software download Instruction manual

BRESSER Polaris-II 102/600 EQ3 Refractor Telescope with Smartphone Adapter & Solar Filter
NEW - now including a high-quality aperture Solar-filter for safe observation of sunspots, eclipses and planet transits. With the included smartphone camera adapter you can take pictures of your observations right through the telescope's eyepiece. Moon, planets, stars – the BRESSER Polaris-II 102/600 EQ3 lens telescope takes beginners a lot closer to the beauties of the universe. The complete set comes with everything you need to admire the night sky: the astronomical lens telescope with 102 mm aperture and 600 mm focal length, the equatorial mount, the tripod and a wide range of accessories for exciting astronomical observations. Explore the fascinating surface of the moon and marvel at the sight of the planets. But you can go even further than that, because the entry-level telescope also shows you star clusters and gas nebulae in the deep sky range. Operation is very easy – so you are off to a successful start in astronomy in no time. Getting started in astronomy with a classic – the telescope Effortless handling, impressive images: As an easy-to-use Fraunhofer-type achromatic refractor, this classic lens telescope is the perfect first telescope for beginners and children. Thanks to its modern, precisely coated optics, it offers good imaging properties as well. The 102 mm aperture already collects a lot of light from the celestial objects. In addition, 102 mm aperture and 600 mm focal length result in an average focal ratio (ratio of aperture to focal length) of about 1 to 6 (F/6). Because of this average focal ratio the beginner’s telescope is an all-rounder for all celestial objects. So observe interesting details on the moon and planets with high magnifications. Or choose a medium to low magnification and admire the sight of open star clusters such as the Pleiades, globular clusters like M13 or gas nebulae like the Orion Nebula M42. Speaking of magnifications: How big will the celestial objects appear through this telescope for beginners? The aperture of 102 mm achieves a resolving power that easily allows magnifications of up to about 200x with sharp images. Technically, the telescope can do more. However, with increasing magnification, the images can become blurred. And the telescope is not the only factor determining the possible degree of magnification. The air turbulence in the atmosphere (seeing conditions) also plays a major role. Solid base for your celestial exploration – mount and tripod Found the perfect observation site? Then set up the telescope on the height-adjustable aluminium tripod with equatorial mount. The advantage of equatorial mounts: Unlike with an azimuthal mount, you don’t have to move both axes at the same time. Instead, one axis is simply aligned parallel to the Earth's axis at the beginning. In this so-called alignment, you point the axis in the direction of the polar star. After that, you can track the celestial bodies just on this one axis. Another benefit of this mount: you move the axes via two flexible shafts with fine adjustment. Perfect for delicate as well as comfortable adjustment and tracking of the entry-level telescope. To ensure that your accessories are always within reach during fascinating discoveries, there is an extra storage plate 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! Everything for your first steps in stargazing – the accessories The astronomy set contains lots of accessories so that you can immediately set off on your discovery tour of the night sky. Use the LED finder to precisely align your beginner's telescope and thus find celestial objects more easily. You just have to install the direction finder in parallel on your telescope. It projects a red dot onto a small ground-glass screen that appears to be floating in front of the sky when you look through. Since the aperture of your telescope points in the exact same direction, this helps you to keep track of the night sky. Two eyepieces (K-20mm, K-4mm) are included so that you can admire celestial bodies in two different magnifications. Still not enough for you? Then simply triple the magnification of the eyepieces with the 3x Barlow lens. And should you ever wish to change perspective during your astronomical observations, the standard tube diameter of 31.7 mm (1.25 inch) gives you a wide choice of additionally available eyepieces. The 90-degree star diagonal mirror, on the other hand, provides more convenience and a comfortable view. Even if your entry-level telescope is pointed vertically upwards, you can simply look in from the side. Discover the wonderful world of astronomy with the BRESSER Polaris-II 102/600 EQ3 lens telescope.
