Product information "EXPLORE SCIENTIFIC Teleextender 2x 31.7mm/1.25""
With teleextenders it is possible to extend the effective focal length of a telescope system, resulting in higher magnification for the observation of the moon, the planets or small Deep-Sky objects with the same eyepieces. So you can use the advantages of eyepieces with longer focal length - such as the bigger eye distance and the more relaxed observing comfort - at high magnifications also.
These teleextenders incorporate a telecentric optical design that deliveres a excellent image sharpness over the whole field of view and are premium choices for visual observations and astrophotography. The combination of excellent fully multicoating with superior optical design makes the Focal Extenders superior to classic Barlow lenses.

Features: 
  • Suitable for visual observations and astrophotography
  • Doubling the effective total focal length of the telescope
  • Four lens telecentric design
  • Fully multicoated
  • Filter thread for color or nebula filters

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 LER Zoom Eyepiece 8-24mm 1.25''
One eyepiece for every occasion The BRESSER zoom eyepiece covers the large focal length range from 8 to 24 mm. These are also the focal lengths most frequently used with most telescopes. Especially for instant observations, where you don't want to pack a whole suitcase full of eyepieces, the zoom eyepiece is a good choice. Always the ideal magnification on hand A quick turn and the ideal magnification for you is set. The adjustment is stepless from 8 to 24 mm focal length. This eliminates the need to always change eyepieces. Comfortable viewing The BRESSER zoom eyepiece offers a large comfortable eye relief of 20 mm to the eyepiece lens (LER = long eye relief). This means comfortable viewing even during longer observation, an important criterion especially for people with glasses. The rubber eyecup can also be individually adjusted by a twist and turn movement. Apparent field of view is 40 up to 56 degrees which offers a good overview. Advanced optical design To achieve the best possible image over the entire focal length range, a sophisticated optical design with 8 lenses in 5 groups is used. The full multi-coating on all lens surfaces also guarantees maximum light transmission. To effectively suppress unwanted reflections, all lenses are carefully blackened at the edges. Thus, the image produced offers the maximum possible contrast and image brightness. Compact and solid design The BRESSER zoom eyepiece is made entirely of black anodised aluminium. It has an extremely solid and high-quality material appearance and is long-lived even with extensive use. The precise zoom mechanism can be operated safely through the ribbed metal adjustment ring. A white laser engraving with focal length and pointer arrow indicates the currently set focal length even in low light.

EXPLORE SCIENTIFIC 82° Ar Eyepiece 11mm (1,25")
Explore Scientific 82° Series™ extreme wide field eyepieces are optimized to produce high contrast, high resolution, and superior flat field characteristics. The visual effect of these eyepieces with their long eye-relief and their 82° apparent field is truly a full-immersion experience. Your eye is relaxed, allowing you to easily use the "averted vision" technique to study faint details across a huge field-of-view. The 82° Series eyepieces come with a twist-up rubber eye-guard that raise to the desired height for the comfort of the observer, and as experienced astronomers know, eye comfort is critical when trying to observe at the visual limits of the telescope. To keep internal reflections to a minimum, all internal surfaces of the eyepiece barrel are flat black, as well as the edges of the lenses themselves to minimize the scattering of light within the lenses themselves. All 82° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.

EXPLORE SCIENTIFIC 2" UHC Nebula Filter
One of the most important obstacles for the exploration of the night sky is the brightening of the night sky by artificial lights, such as streetlights. The night sky is not really dark in the vicinity of towns or cities, which reduces the visibility of objects beyond the solar system enormously. Depending on the type of the celestial object, it is possible to dramatically increase the contrast by blocking annoying artificial light. The EXPLORE SCIENTIFIC UHC filter "zeros in" on the wavelengths of so-called emission nebulae. Those objects glow in special colours - their emission lines. Those emission lines are linked to chemical elements - in this case hydrogen at 486nm and 656nm, plus oxygen at 496nm and 501nm. The EXPLORE SCIENTIFIC UHC nebula filter blocks all other colour wavelengths (and thereby nearly all of artificial light) and only the emission line of the hydrogen and oxygen can pass the filter. The result is astonishing: suddenly nebulae are visible at locations that were completely invisible from, without filters. In suburban skies, for example the Owl-nebula M97, the Veil-nebula NGC 6992 or even the bright Dumbell-nebula M27 are not clearly visible. Using this filter allows you to see nebulae and their structures in much finer detail. A must for every visual observer. The Explore Scientific nebula filters come with a individual test certificate - your guarantee to receive a premium filter.

BRESSER Messier AR152L/1200 EXOS-2 PMC-Eight GoTo Telescope Set
Perfect for ambitious planetary observers: the set consists of the BRESSER Messier AR-152L/1200 Telescope and the modern EXOS-2 PMC-Eight GoTo Mount. With the large aperture and long focal length of 1200 mm, the high-quality optics deliver razor-sharp, high-contrast images that impress with every observation. The telescope is especially suitable for detailed views of Mars, Jupiter, and other celestial bodies. You can also explore the sun using the included objective filter. The mount is equipped with a precise GoTo control and is very easy to use with the intuitive ExploreStars App. Thanks to the extremely accurate tracking, the selected celestial object is guaranteed to always stay in the field of view. The Telescope For demanding planetary observers, the BRESSER Messier AR-152L is the dream device. Discover structures in Jupiter’s cloud bands, the finest grooves and craters on the moon’s surface, and structures on Mars, including the ice-covered polar caps of our neighboring planet! Observe the dance of Jupiter’s moons around the planet and discover the greenish glow of Uranus far beyond Saturn’s orbit. The combination of large aperture and long focal length enables sharp, high-contrast images that will impress you every time. And with the high-quality objective solar filter, you can also safely observe our own star. (Caution: Never point the telescope at the sun without a solar filter!) The Mount The EXPLORE SCIENTIFIC EXOS-2 PMC-Eight GoTo Mount is equipped with a modern and very precise GoTo control system. It consists of a robust Wi-Fi controller unit that provides all the necessary interfaces. The NEMA-11 stepper motors are directly connected to this unit via cable, and an ST-4 compatible autoguider interface is also available. In addition, the control system supports micro-stepping to ensure precise tracking. Intuitive operation via app and graphical star chart The ExploreStars App, developed specifically for the PMC-Eight system, impresses with a very well-designed, intuitive user interface. The currently available alignment stars for initializing the control system, as well as all celestial objects in the database, are displayed as a star chart with additional text information. All these objects can be easily viewed and selected. Powerful controller unit with Open GoTo for customization The heart of the controller unit consists of a completely autonomous 2-channel multi-processor with 8 CPUs and a Wi-Fi Ethernet 10/100 adapter with IP function. This allows remote operation via browser, ASCOM, app, or serial connection. The Open GoTo also allows you to write your own firmware and upload it to the controller unit. This enables custom adjustments to the device’s functions as well as the creation of custom object lists, etc. Polar finder included The included and pre-installed polar finder scope allows for quick and precise alignment and long exposure times without unwanted star trails. The integrated LED lighting unit further enhances the comfort of using the polar finder.
