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 Messier MCX-102 GoTo Telescope EQ/AZ
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 MESSIER MCX-102 telescope is your own small observatory with GoTo computer control. Easy to operate, easy to transport and universally use.  Observe moon, planets, galaxies and nebulae through the proven BRESSER Maksutov-Cassegrain optics. The main features of this optics are a sharp and high-contrast image, as well as the very compact and sealed tube design. An all-round telescope for all fast spotting lovers ! Goto systems play an important role in the world of amateur astronomy as they ensure that users spend less time searching for celestrial objects and more time observing and photographing. The BRESSER Messier GoTo control, allows you to operate your telescope with the included computer handbox. After entering the basic data such as date, time and location, at least 1 known reference star is approached and confirmed. Afterwards, you can choose your favourite objects from the integrated database and let the MCX telescope move to and track them automatically. It couldn't be simpler! One of the outstanding features of the MCX telescopes is the very solid fork mount made of die-cast aluminium and the universal field tripod made of stainless steel. Both guarantee a safe stand and as little unwanted vibrations as possible during observation. In addition, the drives in both axes are equipped with precision ball bearings and precision worm gears made of steel and brass. This ensures smooth and quiet star tracking. Adapt your smartphone camera directly behind the SPL26mm eyepiece using the included smartphone holder or mount your camera on the M35 threaded connector and take astro photos of the moon and planets. The 90° flip mirror at the back of the telescope allows a quick and comfortable change between using an eyepiece or a camera.  You'll be amazed at what this MCX telescope can do with little effort.When it comes to tracking the stars with a telescope or camera, there is nothing comparable to the precision of a German equatorial or parallactic mount. It is important to follow the objects as precise as possible when they rise in the east and sink in the west. For observers it is very easy to keep their celestial object in the middle of the eyepiece for a longer time with a German equatorial/parallactic mount. This possibility of setup  (EQ mode) is already included in your new MCX telescope. The so-called polar wedge on the tripod head can be tilted accordingly and adjusted to the latitude of your location. You can therefore quickly switch between these two types of installation (AZ/EQ) - without having to buy extra accessories! Also a fast use of the MCX telescope without tripod only as a table device is possible !  This telescope combines so many good characteristics that the purchase is really worthwhile. You will be inspired! FEATURES Universal and compact entry-level telescope with GoTo function Easy operation and transport High-resolution and proven BRESSER Maksutov-Cassegrain optics Aperture diameter: 102mm , focal length 1470mm FMC fully coated optics for a brighter image Solid die-cast aluminium fork mounting with drive motors in both axes Proven Goto control for navigation in the starry sky Computer hand box with very large and illuminated display Multilingual menu navigation in DE, GB, FR, ES, IT Sturdy stainless steel tripod with polar wedge (AZ+EQ mode possible) Can also be used without a tripod as a table-top unit Flip mirror 90° - quick change between eyepiece and camera possible Battery compartment integrated in the base for 8 x AA batteries (Batt. not included) Integrated circular bubble for easy leveling Enlarged primary mirror (116mm) for a brighter image Precise worm gears made of steel/brass in both axes Manual gear clamps in both axes Smartphone holder included for photography through the telescope LED red dot finder with CR-2032 battery included BRESSER Super Plössl eyepiece 26mm (1.25") included (56x) Eyepiece shaft diameter: 31.7mm (1.25") Camera connection thread: M35 x 1 mm External connection for 12 Volt power supply: Yes Adjustable working height on tripod: 105 - 155cm Recommended magnifications: 36x - 204x Telescope for night and solar observationSCOPE OF DELIVERY Optical MCX Tube in Fork Mount GoTo Computer Handbox with Hand Strap Field tripod with polar wedge AZ/EQ Smartphone holder for photography through the telescope BRESSER Super Plössl eyepiece 26mm (1.25") LED red dot finder, objective dust cap, Aperture solar-filterInstruction manual

BRESSER Space Explorer 150/750 Telescope with EQ3 Mount
The BRESSER Space Explorer 150/750 Telescope with an EQ-3 Mount shows you the night sky in stunning detail. Go on a journey into distant worlds: Thanks to the combination of a large 150 mm aperture and a short 750 mm focal length, you can marvel at a vast array of celestial objects such as large nebula, open star clusters or the Andromeda galaxy. The powerful Newton reflector telescope is also great for observing our own solar system: with the 25-mm Plössl eyepiece, you can view the moon in 30x magnification. The premium parabolic primary mirror produces significantly sharper images and better contrasts than a comparable telescope with a simple spherical mirror. In addition, the telescope also has a large 55 mm secondary mirror that illuminates the field of view perfectly to create a bright image. Portable design - with the 150/750 reflector telescope Can't wait to get out of the house to view the Orion Nebula or the Pleiades? With this telescope, you can search for the perfect observation spot: thanks to the short focal length, the tube is short and easy to transport. In addition, the premium equatorial mount allows even beginners to set up the telescope in no time. Tracking is also very simple - you can compensate for the earth's movements manually so that your observed objects stay within the field of view. To ensure maximum viewing comfort, the focuser on this Newton reflector telescope is attached to the side of the tube. The aluminium tripod is height-adjustable and features an accessory tray so that you can keep all your important gear within reach. The 6x30 finder scope with reticle allows you to align the telescope with objects in the night sky. The reticle indicates the position at which your telescope is pointing. If you want to capture images of your nighttime discoveries, you can connect your smartphone to the telescope via the smartphone camera adapter.
