BRESSER Pollux-I 150/750 EQ3 Reflector Telescope with Smartphone Adapter & Solar Filter
Explore hidden worlds through your own eyes – with the BRESSER Pollux-I telescope starter set for budding amateur astronomers, you can go on your own journey of discovery in outer space. Everything you need is already included: the astronomical reflector telescope with 150 mm aperture and 750 mm focal length, the equatorial mount, the tripod and a wide range of accessories for astronomical observations. Perfect for getting started quickly: the system is very easy to use. In addition, the entry-level telescope impresses with its versatility: you can observe the Moon and planets as well as star clusters, gas nebulae and even galaxies through the high-quality optics. Due to the parabolic primary mirror the image delights with impressive sharpness and high contrast. In addition, the 2-inch focuser allows for the use of high-quality eyepieces. Perfect conditions for fascinating sights of the night sky! Time-proven optics for your first astro-steps – the telescope By choosing the Pollux-I, you’ll start your journey to the stars with a classic Newtonian reflector telescope. Beginners are often surprised by the fact that with telescopes of this type you don't look in at the back of the tube, but at the front and laterally. This gives you the advantage of always being able to look into the telescope in a comfortable posture, even when it's pointed vertically upwards at the sky. In addition, these reflector telescopes offer optics that are absolutely free of chromatic aberrations and thus provide good imaging properties. The large aperture of 150 mm collects a lot of light from the celestial objects. In addition, 150 mm aperture and 750 mm focal length result in a short focal ratio (ratio of aperture to focal length) of 1 to 5 (F/5). On the one hand, this makes the telescope fast and provide a bright image. On the other hand, high magnifications can be achieved. This combination makes the entry-level telescope so versatile. In addition, the Pollux-I is equipped with a parabolic primary mirror. The remarkable effect of this special mirror shape: you enjoy excellent imaging properties at all magnification levels. So you can look forward to the complete range of celestial highlights. At low to medium magnification, you can admire deep-sky objects such as open star clusters, globular clusters, gas nebulae and even galaxies such as the pair of galaxies M65 and M66 in the constellation Leo. And at high magnifications, observing the planets or details on the Moon is an absolute pleasure. You can get really close to your favourite objects: The aperture of 150 mm achieves a resolving power that allows magnifications of up to about 300x with sharp images. Technically, even higher magnifications are possible, theoretically up to 562.5x using the included accessories. However, with increasing magnification, the sharpness of the image can slowly decrease. In addition, the prevailing conditions always make a difference: How highly you can magnify always depends not only on the power of the telescope but also on the air turbulence in the atmosphere (seeing conditions). The telescope also impresses with its flexibility in terms of eyepiece compatibility: it comes with a 2-inch focuser (focuser extension) and an adapter from 2 inch to 1.25 inch. This enables you to use eyepieces with 1.25-inch sockets (about 31.7 mm) as well as eyepieces with the larger 2-inch sockets (about 50.8 mm) with large fields of view. Note for nature lovers: If you choose a Newtonian telescope like the Pollux-I 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. Perfect foundation for fascinating discoveries – mount and tripod Your beginner's telescope is securely held by the height-adjustable aluminium tripod with equatorial mount. The special feature of this mount, also known as a parallactic mount: in contrast to azimuthal models, the movement of the celestial bodies is only compensated for on one axis instead of two. For this purpose, you simply align one axis parallel to the Earth's axis by pointing it approximately at Polaris. For precise and comfortable alignment and tracking of the entry-level telescope, the Pollux-I comes equipped with two flexible shafts with fine adjustment. And to ensure that the interchangeable eyepieces, barlow lens etc. always remain within reach, they can be stored 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! Well equipped for the ideal start – the accessories Your entry-level telescope comes with a wide range of astronomy accessories so that you can start to be amazed right away. For example, the LED viewfinder helps you align the telescope and find celestial objects. Installed in parallel on the telescope, this direction finder shows you a red dot when you look through it. It appears to hover in front of the sky and thereby shows you where the telescope is pointing. Varying view of the sky: With the two eyepieces with 1.25-inch sockets (31.7 mm), you can admire your astronomical discoveries at different magnifications. The 3x barlow lens already included in the set triples the magnification of the eyepiece you are using. Enjoy safe observations of our Sun with the included solar filter. This way you can easily take a closer look at sunspots and granulation on our own star. CAUTION: Never point the telescope at the Sun without the solar filter! Astrophotography for beginners: with the smartphone adapter, you can use your mobile phone as a camera on the telescope. This way you will quickly impress friends and relatives with your own first snapshots e. g. of the Moon or the Sun.

NATIONAL GEOGRAPHIC 114/500 Compact Telescope
With its 114-mm aperture, this telescope collects three times more light than a 76-mm telescope. Therefore, fainter objects become visible, and you can see more details of the moon and planets. Nevertheless, the telescope is very compact and sets up quickly, with no assembly required, so it can be transported to your favourite night-sky-observation location easily. Use is very intuitive, without compromising stability. The built-in accessory tray keeps the eyepieces handy, and the red-dot finder makes locating objects simple.Please note: Reflector telescopes with optical design “Newton” are very good for astronomical observing at the starry night sky. But these telescopes are not well usable for observing landscape and nature during daylight. Therefore we suggest refractor (lens) telescopes for landscape and nature observing.

BRESSER Venus 76/700 AZ Reflector Telescope with Smartphone Adapter & Solar Filter
The BRESSER Venus 76/700 AZ reflecting telescope allows beginners to experience their very own stargazing hours quickly and easily. With the complete set, you are equipped with everything you need for your very own sky observations: an astronomical reflecting telescope with 76 mm aperture and 700 mm focal length, an azimuthal mount, a tripod as well as extensive accessories. And to guarantee a successful start in astronomy, the system is very easy to handle – the perfect first telescope for beginners! Established technology for your easy start – the telescope With this entry-level telescope, you will be able to admire the night sky through a classic Newtonian reflector. A little surprising for astronomy novices: with this particular type, you do not look in at the back of the telescope, but at the front and laterally. The advantage: even if the telescope aperture is directed vertically towards the sky, you can make your discoveries very comfortably. No need to bend down! In addition, the Newtonian reflector is very easy to use. The optics in this type of reflector telescopes are also impressive, because they are free of chromatic aberrations – resulting in good imaging properties at all times. A sharp image with good contrast – the Venus reflector telescope achieves this with its large focal ratio of about 1 to 9.2 (F/9.2 – calculated from 76 mm aperture and 700 mm focal length). Thanks to its long focal length, the telescope for beginners shows you the Moon, Sun, planets, open star clusters as well as globular clusters in a particularly impressive way. And all this at a magnification of up to 150x in really sharp images! Technically, you can magnify even higher – theoretically up to 525x while using the included accessories. However, as the magnification increases, the sharpness of the image may slowly decrease. Of course, how much you can magnify depends not only on the resolving power of your telescope. The air turbulence in the atmosphere (seeing conditions) also plays an important role. Note for nature lovers: If you choose a Newtonian telescope like the Venus 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 a successful start – mount and tripod The height-adjustable aluminium tripod and the azimuthal mount provide a firm footing and easy celestial navigation. Especially the azimuthal mount makes life easy for beginners, because it is very user-friendly: just like a typical photo tripod, you turn the telescope by hand to the left and right, up and down. This way, your favourite celestial objects quickly appear in your field of vision. Handy: to ensure that your astronomy accessories are always within reach, there is a storage plate between the tripod legs. Everything that goes with it – the accessories Out of the box straight to the fun of observing – with the complete astronomy set, you are quickly on your way to discovering the universe. The LED viewfinder helps you keep an eye on the sky. You just mount the direction finder parallel to the actual telescope and it projects a red dot onto a small ground-glass screen. This then appears to be hovering in front of the sky when you look through the viewfinder. And it does so at exactly the same spot that your telescope is pointed at. This way, the LED finder helps you to align the reflector telescope precisely and to find the celestial objects more easily. When it comes to the level of detail in your observations, the Venus beginner's reflector telescope gives you a choice: the two included eyepieces (4 mm and 20 mm) allow you two different magnifications. You want to get an even closer look? Then simply triple the magnification of the eyepieces with the 3x Barlow lens. In addition, the socket diameter of 31.7 mm (1.25 inch) complies with an international and manufacturer-independent standard. So you can easily expand your set – and with it your astronomical horizon. If you want to observe fascinating sights not only at night but also during the day, simply grab the solar filter. With it, you can safely admire spots and granulation on our nearest star – the Sun. CAUTION: Never point the telescope at the Sun without the solar filter! A new hobby leads to new impressions – and naturally you want to capture and share those. Therefore, you can easily use your mobile phone for your first steps into astrophotograpy with the smartphone adapter. Perfect for great snapshots of the Moon or the Sun, for example. Look forward to exciting astronomical discoveries by day and night – with the BRESSER Venus 76/700 AZ reflector telescope.
