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.

Take a closer look at the wonders of the universe. This complete telescope set for beginners contains everything you need for your new hobby: a refractor telescope with 80 mm aperture and 900 mm focal length, an equatorial mount, a tripod and a wide range of accessories for astronomical observations. The system is very easy to handle and can even be used by children. Simply unpack, set up and get started – you will be amazed at what you will discover! Easy start with user-friendly classic – the telescope The astronomical telescope is a traditional lens telescope, a so-called Fraunhofer achromatic refractor. The advantage of this established telescope type: even beginners and children find it easy to operate. In addition, the BRESSER Quasar scores points for its modern, precisely coated optics with good imaging properties. A direct comparison shows: With its 80 mm aperture, this telescope already collects 30 % more light than a 70 mm telescope and the resolving power is better as well. This means that you can already marvel at some of the details on Mars through the Quasar. In addition, 80 mm aperture and 900 mm focal length mean a large focal ratio (ratio of the aperture to the focal length) of about 1 to 11.3 (F/11.3). The result: a very sharp image with good contrast. Due to its long focal length the entry-level telescope is a specialist when it comes to observing the moon, sun, planets, open star clusters and globular clusters. But you can also take a look at many gas nebulae through this telescope, such as the famous Orion Nebula M42 or the Ring Nebula M57. How big will you see the fascinating celestial bodies? The 80 mm aperture achieves a resolving power that easily allows magnifications of up to about 160x with really sharp images. Technically, much more is possible, theoretically up to 675x using the included accessories. However, with increasing magnification, the sharpness of the image can slowly decrease. In addition to the equipment, the conditions play a role as well: the air turbulence in the atmosphere (seeing conditions) also determines how much you are able to magnify. Sturdy base for your easy astro-beginning – mount and tripod Found the perfect spot for your nocturnal explorations? Then install the telescope effortlessly on the height-adjustable aluminium tripod using the equatorial mount. The advantage of this type of mount: unlike the azimuthal models, you compensate for the movement of the celestial bodies along just one axis instead of two. To do this, you align one axis parallel to the Earth's axis, which is called "alignment". This is easily done by pointing it approximately to Polaris. The beginner's telescope also comes with two flexible shafts with a fine adjustment, which simplify the movement of the axes. They make adjusting and tracking very precise and comfortable. Handy storage: On a plate between the tripod legs, you can store your accessories within easy reach.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! The complete package for your sky observations – the accessories The extensive astronomy accessories including a safe solar filter enable you to immediately direct your gaze through the lens telescope to the sky – day and night. When observing at night, the LED viewfinder helps you find your way around: just install it parallel on the telescope, adjust it and use it to align and locate celestial objects. When you look through it, the red dot projected onto a ground-glass screen inside appears to hover in front of the sky. It shows you the spot to which the tube is pointing. This allows you to navigate easily before taking a closer look with the telescope's high magnification. Different perspectives of your astronomical discoveries are made possible by the two eyepieces, which enable different magnifications. With their sockets, which have a standard diameter of 1.25 inch (31.7 mm), they are simply inserted into the telescope's focuser. You want to see even more details? Then triple the magnification of the eyepieces with the 3x barlow lens. Always comfortable while observing the stars – for this purpose the 90-degree star diagonal mirror is included. That way you always enjoy a pleasant view into the telescope. Even if it is pointed upwards into the sky, you can comfortably look in from the side. Discover the beauty of our own star: Using the telescope in combination with the solar filter you can safely observe sunspots and granulation on the sun. CAUTION: Never point the telescope at the sun without the solar filter! Have you always been fascinated by astrophotography? Then your smartphone camera and the smartphone adapter will get you started. This way you'll quickly enjoy your first own photos e. g. of the moon or the sun.

Universal 60mm viewfinder and guide telescope with a focal length of 250mmExcellent 10x60 viewfinder telescope with removable eyepiece unit and crosshairs with adjustable red illumination. The larger aperture and focal length, provide an even brighter field of view and more accurate tracking due to the higher resolution. The precise helical focuser and the 1.25 inch /31.7mm plug-in connection, as well as the T2 camera connection thread (M42x0.75mm), allow the autoguiding required for long time exposure to obtain a point-shaped star image. It can also be used as a mini travel telescope.High quality 10x60 viewfinder telescope with adjustable crosshair illuminationImage sharpness and viewing characteristics lift this viewfinder well above the level of the usual 10x60 viewfinder scopes. The visible image is bright and crisply sharp. Furthermore, this viewfinder has a very large field of view (FOV) of 6.0 degrees. This makes finding and adjusting objects much easier. The existing scale markings (pitch=0.85 degree) on the crosshair are a good reference for estimating distances, and the open centre markings also make it easier to centre objects precisely. All lens surfaces are protected against weathering by multi-coating and guarantee a bright viewfinder image due to the high light transmission values. The adjustable red LED illumination unit is powered by two LR41 coin batteries. The main lens and the crosshairs can be focused independently of each other, giving you perfect focus for your eyes.Compact tracking unit for autoguidingOne of the main applications for this telescope is the so-called autoguiding. Here the usually larger photo-taking optics are actively corrected by a smaller guiding telescope with a second tracking camera. This means that the mechanical fluctuations in the tracking accuracy, which are present in all astronomical telescope mounts, are measured by the tracking camera and compensated accordingly. This is necessary in order to obtain a point-shaped star image on the astrophotos during long time exposures and to avoid unwanted star trails. For this purpose, the guiding telescope is inserted into the existing viewfinder shoe of the photo-taking optics and aligned parallel. If the existing viewfinder shoe is not compatible, a suitable viewfinder shoe is also included. With the 1.25 inch / 31,7mm plug connection at the rear end or via T2 thread connection (M42x0,75mm), a tracking camera can be mounted afterwards. This is held securely by a brass ring clamp and 3 clamping screws. Please note the required back focus for your tracking camera. The focal plane (backfocus) is approx. 22mm behind the T2 thread. The sensitive focusing on the guiding star is done by a large knurled wheel of the mechanically precise manufactured helical focuser. For easy reproduction of the point of focus, this has a white millimetre scale from 0 to 28mm, which is attached by laser engraving. After the tracking camera has been connected directly or via computer to the telescope mount and the necessary basic settings have been made, the first astrophotos with long time exposure can be taken.Use as mini travel telescopeThis viewfinder and guide telescope can also be used quite simply as a mini travel telescope. With the optional eyepieces, a magnification of 9x to 50x can be achieved. Nearly all eyepieces with a focal length of 5 to 26mm and 1.25 inch/31.7mm plug connection are suitable. Especially recommended are the EXPLORE SCIENTIFIC eyepieces of the 52 degree (Art. 02195xx) and 62 degree (02196xx) LER series. Note: Only straight view use is possible.Metal viewfinder holder and viewfinder shoeThe mount of this viewfinder and guide telescope is completely made of aluminium and is a stable base. The viewfinder mount is suitable for many common types of telescopes, such as EXPLORE SCIENTIFIC, BRESSER MESSIER etc. If the existing viewfinder shoe is not compatible, a matching viewfinder shoe is also included. This can be attached to the telescopic tube by means of four M5 screws. The bore distances of the viewfinder shoe are 31.7mm on the longitudinal and transverse axis. The six large adjustment screws with non-slip knurling make it easy to align the viewfinder, even with clammy fingers. All adjusting and clamping screws have plastic tips that effectively prevent the viewfinder housing and viewfinder mount from being scratched.FEATURESExcellent 10x60 viewfinder and guiding telescopeCan also be used as mini travel telescopePerfect image sharpness and good viewing comfortFMC Multi-coated lens surfacesLens focal length: 250mmMax. possible camera weight: 550gRemovable eyepiece/cross hair unitCamera connection via 1.25 inch / 31.7mm plug connection or T2 threadT2 thread: M42 x 0,75mmPrecise helical focuser for focusing the visible imageFocuser travel range: 28mmClose focus distance: 3 mLaser engraved millimetre scale from 0 to 28mm on the focuserFocal plane (backfocus) is approx. 22mm behind the T2 threadSeparate focusing of the crosshair at the eyepieceVery large field of view FOV of 6.0 degreesWith adjustable red cross-hair iillumination Scale markings crosshair with 0,85 degree graduationPower supply of illumination unit: coin battery type LR41 (2pcs)Brass ring clamp and 3 clamping screws on the 1.25 inch plug connectionWith optional eyepieces magnifications from 9x to 50x can be achievedSuitable are almost all eyepieces with 1.25 inch/31,7mm shaftMounting of the viewfinder telescope is completely made of aluminiumViewfinder mount with 6 large adjustment screws with knurled head for easy gripFinder shoe suitable for EXPLORE SCIENTIFIC, BRESSER MESSIER etc.Additionally a suitable viewfinder shoe is includedBore distances of the viewfinder shoe are 31.7mm on the longitudinal and transverse axisAdjusting and clamping screws have plastic tipsWHAT'S INCLUDED10x60 viewfinder/guiding telescopeEyepiece unit with crosshairCrosshair illumination unit incl. batteriesViewfinder holder with viewfinder shoeInstruction manual

Color Filter Set Essential is recommended for Moon & Planets from 50mm (2") Aperture Essential Set includes the following filters: BRESSER Filter Red (1,25):The blue/blue green light is totally blocked. The contrast between the card and the lighter zones will enormously increase. This is truly helpful when you watch Jupiter or Saturn. Or for mars, watching the poles. BRESSER Filter Green (1,25):The green filter is to increase the contrasts enormously between the red and the blue regions of the cloud structures on the gas planets Jupiter and Saturn. Seeing our Earth Moon through the green filter, the contrasts of each ray crater become clearly more visible.BRESSER Filter Blue (1,25):The color of light blue really supports watching the high clouds on Mars. The contrast increases. The dark red structures will be shown even darker, so this is the perfect filter for watching the big red Flecks on the gas planet Jupiter. The rings of Saturn will be accentuated, the structures of the Venus Atmosphere will be even finer. BRESSER Filter Yellow (1,25):Watching the Moon surface through the filter, the contrasts will enormously increase. Same with planet Mars. On the huge planet Jupiter, when using the filter, you can even see the contrasts between the cloud-bands and a lot more details. Starting with a telescope diameter of 8“ and a clear sight, you even get to see various details of Saturn. What ist a color Filter for and do we really need it? Color Filters darken the light slightly, that reaches the eye or the sensor of the camera. This eliminates for instance stronger transitions. The result is that your picture turns out with more contrast which automatically shows more details. FEATURESVersatile colour filter set For eyepieces and accessories with 1.25" filter thread Increase contrast on moon and planets Making object details more visibleSCOPE OF DELIVERY4pcs color filter: Red, Green, Blue, Yellow
