EXPLORE SCIENTIFIC TELRAD Projection Finder Scope with base
The TELRAD viewfinder is a projection finder that can be installed on any telescope and makes it child's play to align the telescope with the starry sky.The TELRAD viewfinder is a practical alternative to classic optical viewfinders and illuminated red dot viewfinders. You can see the complete starry sky without magnification, and not just a small section as with a normal optical viewfinder. Against this background of the starry sky, three red luminous concentric rings are projected, with apparent diameters of 4 degrees, 2° and 0.5° in the sky. Move the telescope so that the object you are looking for is in the inner ring, and the telescope points in the right direction. Because the object you are looking for is inside the ring, it will not be irradiated like a normal illuminated red dot finder.The base of the TELRAD viewfinder is self-adhesive and can be mounted on all telescopic tubes from about 10cm diameter. The length of the base is about 18cm. This base remains on the telescopic tube, the TELRAD viewfinder itself can be removed or attached at any time by means of the attached quick coupling. The TELRAD is powered by two normal AA batteries (not included).There are star atlases, like the "Deep Sky Travel Atlas" from Oculum-Verlag, and planetarium programs for the PC, like the program "Stellarium", where the three rings of the TELRAD are already drawn or can be displayed around the interesting celestial objects. This makes finding these celestial objects a real walk.FEATURESTELRAD projection finderIlluminated rings of 4 degrees, 2° and 0.5° in the skySee the complete starry sky without magnificationEasy installation and useCan be installed on nearly every telescopesBase with quick release coupling included Powered by two AA batteries (not included) Very long battery life because of LED technologySCOPE OF DELIVERYTELRAD viewfinder with projector and battery compartment TELRAD base with quick-release coupling for the viewfinder Adhesive tape for attachment to telescope

EXPLORE SCIENTIFIC 52° LER Eyepiece 30mm Ar
Loved by deep sky observers, a 30mm focal length eyepiece produces a large exit pupil which floods your dilated eye with light, which is needed to see faint galaxies and nebulae. Low power eyepieces are very important to observers for a variety of reasons: Their wide true field of view make object location and pointing far easier. Many deep sky objects are large and are best viewed at the lowest magnifications your telescope/eyepiece combination can achieve. When seeing conditions are poor, objects will often still look sharp at low powers.Comfort, Quality, Value. The Explore Scientific 52° LER Series mid-range focal length eyepieces are excellent flat-field multi-element oculars that can transform your visual astronomy experience. With an apparent field of view of 52 degrees, these eyepieces offer incredible value in a very nice eyepiece. Expect exceptional quality and value versus a comparably priced Plossl.  These eyepieces are the choice for observers wearing glasses - with excellent performance and durability. The rubber inlet and the foldable eyecups make handling and using in the field easy. The patented EMD"-coating produces high contrast images and prevents reflexes and ghosting. The argon purging effectively prevents internal fogging, and you don´t have to deal with dirt, fungus or cleansing fluids getting between the lenses. The eyepieces are sealed - this makes sure you will be able to enjoy these eyepieces for many years to come.SPECIFICATIONS:Large eye distance, large field and great image sharpnessExcellent viewing position for people with glassesExcellent field sharpness even with fast optics52° apparent field of viewArgon-purging prevents internal fogging, the sealing facilitates cleaningPatented EMD"-coating to maximize contrastBlackened lens edges to avoid reflexesAll eyepieces of this series are parfocalStainless steel barrel with conical security cutoffDust covers and protective bag includedSCOPE OF DELIVERY:52° EyepieceDust coversProtective bag

EXPLORE SCIENTIFIC 52° LER Eyepiece 10mm Ar
Mid-range high power eyepieces like the 10 mm are instrumental when transitioning through magnifications to observe an object until it is best seen. There are several aspects that have to come together when observing at high powers: good-to-perfect atmospheric seeing conditions; telescope optics that are collimated; a telescope that is acclimated to the ambient temperature; brightness and size of the object being observed are just a few aspects to consider. The observing challenges are high, but the rewards of observing at high power with razor sharp views are unforgettable. Comfort, Quality, Value.

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. Explore Scientific Filter 1.25" Orange No.21 - 0310273 This one really supports the detection of the dark areas on the planet Mars. The details of the clouds of Saturn and Jupiter are also so much more visible through the Filter. Explore Scientific Filter 1.25" Blue No.80A - 0310264 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. EXPLORE SCIENTIFIC 1.25" Filter Grey ND0.9 - 0310245 The neutral density filter transmits light uniformly across the entire visual spectrum. It serves as an excellent filter to reduce glare and irradiation when observing the Moon with any telescope 4"(10.2cm) and larger. The ND96 filter may also be employed in the splitting of close double stars where one of the binary pair significantly exceeds the other in brightness. 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.

BRESSER Barlow Lens 2x 31.8mm/1.25"
With the usage of barlow lenses, you can extend the equivalent focal length of telescopes and hence increase the magnification of your observed targets. Subsequently, you can use lower power eyepieces in Barlows to act as much more powerful eyepieces, but retain the larger ocular size and more comfortable viewing that comes with lower power eyepiece designs.Due to their two lens design, these Barlow lenses provide a brilliant image quality for the whole visual field and are suitable for observations and photography.  The black coloured Barlow element cell in this BRESSER Barlow Lens 2x 31.8mm/1.25," can be unscrewed and has the same thread as 1.25" filters, allowing it to be mounted in 1.25" eyepieces, t-adapters and other accessories, giving you flexibility of use and the ability to vary magnification in different accessories.  For instance, the black Barlow cell screwed into the average length nosepiece of a standard push fit t-adapter will give around 1.6x magnification on an attached DSLR.  This can be very useful when trying to get to photographic focus with some Newtonians and Solar Telescopes, which lack the necessary amount of in focus travel to get a camera to a prime focus position.FEATURESsuitable for observations and photographydoubling of the focal lengthtwo lens designfully multi-coatedWHAT'S INCLUDEDBarlow lens (1pc)

BRESSER Galaxia 114/900 EQ3 Reflector Telescope with Smartphone Adapter & Solar Filter
Fascinating Jupiter, breathtaking Ring Nebula and glowing Pleiades – there are infinite beauties to admire in outer space. With this complete telescope set for beginners, you can explore them with your own eyes, and do so immediately. Everything is included for a quick and easy start in sky observation: the astronomical reflector telescope with 114 mm aperture and 900 mm focal length, the equatorial mount, the tripod and a wide range of astronomical accessories. In addition, the telescope can be operated very easily, even by beginners. The Galaxia is particularly suitable for observing the Moon and planets as well as star clusters and bright gas nebulae. Getting started easily with a true astro-classic – the telescope This set enables you to make your first astronomical discoveries through a classic reflector telescope, a so-called Newtonian reflector. For many beginners, the view through telescopes of this type is rather unusual: you don't look in at the back of the telescope, but at the front and laterally. This way you can always enjoy your observations in a comfortable physical position. Even if the telescope is pointed vertically upwards into the sky, you don’t have to bend down. Another important advantage of these reflecting telescopes: the optics are absolutely free of chromatic aberrations and thus score points with their good imaging properties. Due to its aperture of 114 mm, the entry-level telescope already collects a lot of light from the celestial objects. In addition, 114 mm aperture and 900 mm focal length result in a large focal ratio (ratio of aperture to focal length) of 1 to 7.9 (F/7.9). As a result, you’ll enjoy a sharp image with good contrast. The combination of large aperture and long focal length makes especially Moon, Sun and planets look very impressive through this telescope. But you can also use it to observe many deep sky objects. Look forward, for example, to your first impressions of sparkling open star clusters and globular clusters. But also bright gas nebulae such as the Orion Nebula M42 or the Dumbbell Nebula M27 can already be seen with this telescope. However, how close do the celestial bodies appear through the astronomical telescope? The resolving power of the 114 mm aperture allows for magnifications of up to 230x with sharp images. Technically even more would be possible, theoretically up to 675x using the included accessories. But as the magnification increases, the image sharpness can then slowly decrease. And another factor always determines the answer to the question of possible magnification: the air turbulence in the atmosphere (seeing conditions). Note for nature lovers: If you choose a Newtonian telescope like the Galaxia 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 stargazing newbies – mount and tripod You found the ideal place for your start in astronomy? Then go ahead and mount the beginner's telescope on the equatorial mount and the height-adjustable aluminium tripod. This type of mount has a special advantage over azimuthal models: the movement of the celestial bodies is tracked on just one axis instead of two. To do this, you align one axis parallel to the Earth's axis beforehand. This so-called "alignment" is easily done: you simply point the axis approximately to Polaris. Another advantage of this particular mount is that you move the axes via two flexible shafts with fine adjustment. Perfect for comfortable and sensitive adjustment and tracking of your telescope. Always at hand: The extensive accessories can be stored on the shelf 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 you need for your new hobby – the accessories Since the telescope kit comes with an extensive range of accessories, you are perfectly equipped for your first steps in the fascinating world of astronomy. Simply install the LED viewfinder parallel to the tube, adjust it and look through. As you do so, you will see a red dot projected onto a small ground-glass screen inside the viewfinder. It appears to hover in front of the sky at the exact spot where the telescope is pointed. This helps you to find celestial objects and the exact telescope alignment more easily. Simply change your perspective – with the two eyepieces you can marvel at your favourite astronomical objects in different magnifications. They are easily inserted into the telescope's focuser using the sockets, which have the standard diameter of 1.25 inch (31.7 mm). Do you want an even more detailed view? Then simply triple the magnification of the eyepieces using the 3x barlow lens. Astronomical observations are well worthwhile even during the day: enjoy a safe view of sunspots and granulation on our own star with the solar filter. CAUTION: Never point the telescope at the sun without the solar filter! Take your first photos of the Moon or the Sun, and do it easily: the smartphone adapter enables you to attach your smartphone camera to the telescope and soon enjoy your very own astronomical snapshots. FEATURES Reflector telescope with 114 mm aperture and 900 mm focal length Reflector type Newton Well suited for observing Sun, Moon and planets, also star clusters and gas nebulae are visible Height-adjustable tripod with equatorial EQ3 mount Sensitive adjustment through flexible shafts and fine adjustment in both axes Easy to use, very suitable for beginners Focal ratio F/7.9, thus sharp image and good contrast 1,25 inch (31,7 mm) eyepiece focuser Two eyepieces and one barlow lens with 1.25 inch (31.7 mm) extension tubes for different magnifications Safe solar observation with the included solar filter Easy first steps into astrophotography with smartphone camera adapter SCOPE OF DELIVERY Telescope Aluminium tripod Equatorial EQ3 mount Eyepieces: 4 mm and 20 mm (1.25 inch sockets) Barlow lens 3x (1.25 inch socket) LED illuminated dot finder Solar filter Smartphone camera adapter Accessory tray Astronomy software download Instruction manual
