BRESSER Polaris-I 102/460 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.

Complete SXD2WL SD103SII Telescope Set with GoTo Mount, Tripod, and EyepiecesThis high-quality apochromatic refractor telescope set impresses with its 103-mm SD optics. The telescope is made in Japan and stands out for its excellent workmanship, sharpness, and contrast performance.The advantage of this SD refractor lies in its short construction length and its low weight. You will be amazed when you observe the moon's surface with its craters or Saturn with its ring system. On Jupiter, on a clear night, the two bright cloud bands and many smaller details become visible, such as the Great Red Spot on the planet. On moonless nights, you can observe the Andromeda Nebula, Orion Nebula, Eagle Nebula, Lagoon Nebula and many other interesting objects. Even weaker celestial objects become visible with this large aperture under a good sky.This telescope set "Made in Japan" leaves nothing to be desired. The FPL53 glass installed in the telescope reproduces an extremely clear and sharp image by eliminating residual chromatic aberrations to a high degree. The SD glass is designed to bring together all rays – violet, red, blue, yellow, and green – very precisely on the same plane. The special lens material thus reduces chromatic aberration across all colors.With the new Vixen SD103SII, no spacer shims are used anymore, leading to a significantly better image quality for bright stars. Therefore, no spikes are seen on stars in photographs, which were otherwise caused by the spacer shims. In combination with the optional SD Reducer HD Kit or SD Flattener HD (not included), this refractor telescope enables illumination with a 44-mm image circle for full-frame SLR cameras. The older ED81SII, ED103S, ED115S refractors were originally designed for visual observers and photographers with APS-C cameras developed. However, the new SD series is also optimized for the use of full-frame cameras due to the use of new internal apertures. The large 60-mm eyepiece extractor also allows for the attachment of heavy cameras without tilting. Moreover, the supplied folding mirror enables comfortable observation even in unfavorable observation situations and also provides a T2 thread for connecting a DSLR camera. Thus, you can observe in direct view or at a 90° angle . The carrying handle attached to the tube clamps ensures a safe hold during transport of the telescope. The stable metal tripod allows for a vibration-free recording of the telescope and mount even in windy weather. The SXD2WL mount is easily operated via a Wifi module with a smartphone or tablet. The free STAR BOOK Wireless app is available for user-friendly control of the mount. This allows you to use practical celestial navigation functions such as the automatic GoTo swiveling to specific celestial objects very easily via your smartphone or tablet. As the power consumption of the conventional LCD screen (STAR BOOK TEN) is eliminated, the power consumption of the mount is reduced by up to 20%. This enables longer astronomical observations and astrophotography. When you tap on the desired celestial object from a list, it automatically swivels into the telescope's field of view, and tracking begins. An existing STAR BOOK TEN control can also be used on this mount without any problems. Equipped with the same precision stepper motors as the top model, the AXD mount, the SXD2WL introduces a new standard of performance and precision in the Vixen mount family. The axis cross of the mount has a photographic load capacity of 15 kg and weighs just 9.2 kg, making it excellent for mobile observations. In addition, the motors located in the lower part of the mount simultaneously serve as counterweights. This means that the mount needs fewer weights for balance. Details of the SXD2 Mount Precision stepper motors and Micro-Step Motion Control System The heart of the SXD2 is the precision stepper motors, offering better performance and response than previous models. The Micro-Step Motion Control System boasts powerful yet very quiet drive properties, suitable for both fine movements and rapid sweeps. Built-in bearings The bearings of the RA and DEC axes and the worm shafts have been significantly improved to reduce the load on the motors. As a result, the motors move much more quietly than previous models. High-precision worm gears Advanced manufacturing technologies have eliminated errors in the worm drives. The edges of both the worms and worm gears are particularly smooth, allowing very precise tracking. DEC axis as counterweight The massive motor units are built into the lower part of the DEC axis, so the center of gravity of the SXD2 is just below the intersection point of the RA and DEC axes. This reduces the need for additional counterweights. Latitude adjustment The latitude is adjustable between 0 and 70 degrees (divided into 3 zones and adjustable +/- 15 degrees per zone, for high, medium, and low latitudes); latitude scale in 2-degree steps; fine adjustment with a tangential screw head, about 0.8 degrees per rotation. Built-in PFL-II polar finder with illumination The built-in 5x20 mm polar finder with a 10° field of view has a 3-star alignment system. This eliminates the need to set the date and time. The illuminated reticle with variable brightness and automatic shut-off is adjustable in 8 steps and is red illuminated. The alignment accuracy is 3 arc minutes. Details of the Wireless Module The Vixen Wifi adapter for EQ mounts allows you to control your Vixen mount via a smartphone or tablet. With the free STAR BOOK Wireless smartphone app, celestial navigation becomes easy and wireless. This way, the app instantly transforms your mobile device into a controller for the equatorial mount. The reaction delay of the mount, the biggest disadvantage of wireless connections, has been reduced to a level comparable to wired solutions. Reduced power consumption compared to traditional controllers with LCD monitor The power consumption of the mount is reduced by up to 20%, allowing for longer observations than with traditional wired controllers like the STAR BOOK TEN. Operation similar to the STAR BOOK TEN controller The STAR BOOK Wireless App is set up similarly to the STAR BOOK TEN controller. Depending on the star chart setting, it contains up to 259,000 celestial objects. Tap on a celestial object in the object list and start the GoTo. The mount automatically moves to this target and brings it into the telescope's field of view. All the popular features of the STAR BOOK TEN are retained. Comfortable operation While looking through the telescope, you control the mount by swiping on the star chart in the app. Since there are no buttons, you simply swipe your finger over the star chart to comfortably control the mount. Comprehensive astronomical data included This includes data on easily observable celestial bodies such as Messier objects, NGC objects, IC objects, as well as the sun, moon, planets, comets, and dwarf planets. High-precision alignment Alignment on one or two stars already provides a reasonably accurate positioning of the mount. By aligning on three or more stars, a highly precise alignment of the mount for high magnifications can be performed. The objects are then accurately and centrally placed in the telescope's field of view. The alignment information is stored and can also be retained when the device is turned off. By leaving the telescope in its current state after an observation, without moving it, you can start the next observation with the same settings. Individual adjustment options The app offers various individual adjustment options such as gear play compensation, red night mode, autoguider, variable GoTo speed, and LED brightness, similar to the STAR BOOK TEN controller. You can also set the time of the reversal of the objective tube (Meridian Flip) as desired. Even if the object moves south during tracking, you can prevent the telescope tube from reversing. Important information Not suitable for old SX mounts with the old blue Star Book Technical information about the Wifi module CPU with 32-bit CISC processor 120 MHz The unit is connected to the mount via a D-SUB 9PIN connector, similar to the STAR BOOK TEN. Equipped with a 6-pin, 6-wire modular connector for external autoguider operation.

NEW - now including a high-quality aperture Solar-filter for safe observation of sunspots, eclipses and planet transits. Great telescope for night and solar observation.The BRESSER Messier 8'' dobsonian is simply a breakthrough. Despite of its low price this telesccope offers a versatility and quality rivaling a lot more expensive telecopes. The optical diameter of 203mm (8'') does not restrict your observations on solar system objects like the moon or the planets - you can reach farther into the sky and explore globular and open clusters, nebulae and galaxies. With that telescope those objects are beginning to show structures: globular clusters are no longer only fuzzy blobs, but are resolved into masses of individual stars. Nebulae, that can only be barely detected in smaller scopes, reveal structures within. The telescope is setting a new standard in versatility: the excellent Hexafoc focuser boosts a free diameter of 65mm (2,5'') so that you do not have vignetting in big widefield eyepieces that is caused by smaller focuser barrels. The big altitude wheels handle those big, heavy eyepieces without problems - and when you intend to load even more (like a binocular viewer with two eyepieces) then you can move the tube in its tube rings and achieve balance within seconds. The excellent rigidity of the focuser makes focusing a snap - even for astrophotography. This is another virtue of this highly versatile telescope system: you can remove the altitude wheels from the tube rings, attach a dovetail and use the optical tube on a equatorial mount for astrophotography - in minutes. The focuser is handling even heavy cameras tilt and shifting-free. You are extremely demanding in your image sharpness? No problem - with the optional 10:1 gear reduction sharp images are easy. If you consider, that the focuser is that part of the telescope that is used most often, you will recognize the quantum leap this Hexafoc represents in a telescope of this price range. With the included standard accessories (6x30 finder and 25mm SPL-eyepiece) the telescope is ready for observing. If you need to transport or store the telescope as compact as possible you will like this: the rocker box of the 8'' BRESSER Messier assembles and disassembles extremely easy and fast due to the use of metal standard furniture fasteners. So you can transform the bulky rocker box into a handy flat package of boards. This telescope is setting a new standard in usability, versatility and performance in its price class.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 BRESSER refractor (lens) telescopes for landscape and nature observing.

The Vixen VA225C autoguider camera is designed to tackle common challenges in astrophotography, such as atmospheric interference and minor tracking errors that can cause star trails during long exposures. When paired with an optional guide scope, this highly sensitive colour CMOS camera continuously monitors star positions and automatically adjusts your equatorial mount in real time to correct for any deviations. This allows you to capture sharp, long-exposure images — especially useful when using telescopes with longer focal lengths. Beginner-friendly operation The VA225C makes it easy for newcomers to get started with autoguiding. Simply connect the camera to your telescope mount using the included ST4 cable for fully automated tracking control. The dedicated “Vixen Autoguider” PC software offers three preset guiding modes — City, Suburban, and Dark Sky — tailored to different viewing conditions. You can also fine-tune the settings to suit specific locations and atmospheric conditions if needed. Accurate polar alignment — without a polar finder With its built-in plate solving functionality, the VA225C allows for precise polar alignment without the need for a separate polar finder. You can check the alignment accuracy in real time via the software interface and make direct adjustments on the spot. This feature simplifies your setup process and ensures optimal conditions for successful astrophotography sessions. Exceptional sensitivity and flexible connectivity Thanks to its excellent light sensitivity, the VA225C can reliably detect suitable guide stars even with very short exposures. The camera comes with a 1.25" nosepiece for connection to guide scopes or off-axis guiders, a 1.25" filter thread (M28.5x0.6), and a C-mount thread (1" x 1/32"). We recommend the Vixen 7x50mm Finder Scope II (sold separately, item no.: X086161) as a guide scope. Its parfocal design ensures the focus remains consistent when switching between an eyepiece and the camera — so your guide star stays locked in view.
