EXPLORE SCIENTIFIC 68° Ar Eyepiece 16mm (1,25")

This Barlow lens doubles the focal length of your telescope. It allows you to make astronomical observations with a higher magnification than a conventional eyepiece. Thanks to the Barlow lens between the eyepiece, you can obtain a greater magnification whilst maintaining a comfortable interpupillary distance.This Vixen 2x Barlow lens is ideal for observing and photographing lunar landscapes and details on the brighter planets. The Barlow lens also features a T2 connection for photography with DSLR cameras. With T2 extension tubes, it can also be used as a camera projection adapter.With a deflecting prism, the Barlow lens enables you to obtain a magnification factor of 3.3x.FEATURES2x Barlow lenses with T2 thread2-lens optical systemDoubles the magnification factorAlso suitable as a camera adapter31.7 mm sleeveWeight: 80 gDELIVERY CONTENT 2x Barlow lenses Dust caps

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.

Universally usable variable polarizing filter with a  1.25" filter thread.This variable polarizing filter allows for a continuous adjustment of the image brightness. This is very helpful to level strong differences in contrast of different observation objects individually. Particularly for lunar and planetary observations but also for solar observations this filter prevents an outshining of details.Solar observations ONLY together with an adequate solar filter !!! Particularly when a Herschel wedge is used and with large objective lens apertures the use of the variable polarizing filter can reduce the brightness of the observation object to a confortable level. The large adjustment range of 40% to 1% light transmission and the neutral grey filter effect create a comfortable and unadulterated image.The handling is very simple. The desired filtering level is set by turning the two sides of the housing against each other.A 1.25" filter thread on both sides (female/male) allow for the simultaneous use of additional colour filters.FEATURESvariable polarizing filterindividually adjustable image brightnessmade from high-quality optical glassblack anodized aluminium housing1.25" filter thread on both sidesSCOPE OF DELIVERYpolarizing filterprotective box

This telescope set of the Messier MC-127/1900 tube and EXOS-2 PMC-Eight GoTo mount is ideal for beginners in astronomy! With its 1,900-mm focal length and 127-mm aperture, the compact telescope provides sharp planetary views at high magnifications. Discover fascinating details of distant planetary nebulae and star clusters. With the telescope tube’s short length, you can explore the night sky with ease. The modern mount, featuring precise GoTo control and a user-friendly ExploreStars app, ensures accurate tracking and effortless navigation across the sky. And with the high-quality solar filter, you can safely observe our own star. The Telescope The compact optics distinguish the Messier MC-127/1900. Its very long 1,900 mm focal length allows relaxed planetary observations at high magnifications. At the same time, the telescope is ideal for mobile use thanks to its short tube. The 127 mm aperture enables you to observe smaller planetary nebulae in the vastness of space. Marvel at the bright filaments of the famous Orion Nebula, or spot the Dumbbell Nebula in the constellation Vulpecula. With the high-quality solar filter, you can safely admire sunspots, eclipses, and planetary transits. (Warning: 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 highly precise GoTo control system. It consists of a robust Wi-Fi controller unit that provides all necessary interfaces. The NEMA-11 stepper motors connect directly to this unit by cable, and an ST-4-compatible autoguider interface is also available. Additionally, the control system supports micro-stepping for precise tracking. Intuitive operation via app and graphic star map The ExploreStars app, developed specifically for the PMC-Eight system, offers an attractive and intuitive user interface. The app displays the alignment stars available for initial setup and all celestial objects in the database as a star map with additional text information. All these objects can be conveniently viewed and selected. Powerful controller unit with Open GoTo for customization At the core of the controller unit is a fully autonomous 2-channel multi-processor with 8 CPUs and a Wi-Fi Ethernet 10/100 adapter with IP functionality. This setup enables remote operation via browser, ASCOM, app, or serial connection. Open GoTo allows you to write and load custom firmware into the controller, facilitating individual adjustments to device functions as well as creating custom object lists. Polar finder included The included, pre-mounted polar finder scope enables quick and precise alignment and allows for long exposure times without unwanted star trails. The integrated LED illumination unit further enhances the polar finder’s ease of use.

High power eyepieces (e.g. 3mm to 10mm) are used not only for obvious observations of planets and double stars, but can be employed for bright, compact deep sky objects. Not only will the scale of an object like a planetary nebula or globular cluster be impressive as it fills the eyepiece FOV, but the background sky will be very dark as the contrast effect increases with added magnification, provided that the atmospheric seeing conditions are favorable enough to reveal a sharp image. The 4.5mm is a popular choice for a wide variety of telescopes, producing some of the highest magnification views that most astronomers will observe at.Comfort, Quality, Value. The Explore Scientific 52° LER Series Most short 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.
