Vixen SLV 50° Eyepiece 6mm (1.25'')

BRESSER 30mm Plössl Eyepiece 1,25" (31,7mm) Since years a well known and approved Plössl eyepiece. Ideal to improve the performance of your telescopes for a low budget price. All the BRESSER Plössl eyepieces provide sharp and high-contrast images because of the 4-lens design. All lenses have fully-multicoated surfaces which prevents reflections efficiently. Every eyepiece is equipped with a foldable rubber eyecup to avoid straylight from the sides and the inner eyepiece shaft is carefully blackened as well. Housing and eyepiece shaft are completely made from metal - no plastic is used. Filter thread for use with colour- and nebular filters is also available. All these Plössl eyepieces offer a much better image quality than all the very simple made Kellner and Huygens eyepieces.

One eyepiece for every occasion, with very good field correction and large field of view.The BRESSER Zoom Eyepiece Deluxe 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. The Deluxe version offers with its particularly advanced optical design with 9 elements in 6 groups an even better field correction and sharpness, combined with a large apparent field of view of 40 up to 62 degrees.Always the ideal magnification on handA 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 viewingThe BRESSER Zoom Eyepiece Deluxe offers a large comfortable eye relief (LER) of 20 mm to the eyepiece lens. This means a comfortable view even during longer observation, an important criterion especially for people wearing glasses. The rubber eyecup can also be individually adjusted by a twisting movement.Advanced optical designTo achieve the best possible image over the entire focal length range, a particularly advanced optical design with 9 lenses in 6 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 designThe BRESSER Zoom Eyepiece Deluxe 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 adjusted safely through the rubberised adjustment ring. A white laser engraving with focal length and pointer arrow shows the current focal length setting even in low light.Achievable magnifications with common telescope focal lengths350mm: 44 - 15x400mm: 50 - 17x500mm: 63 - 21x650mm: 81 - 27x750mm: 94 - 31x900mm: 113 - 38x1000mm: 125 - 42xFEATURESDeluxe version with even better field correction and sharpnessLarge apparent field of view 40 up to 62 degreesZoom eyepiece with stepless focal length adjustment from 8-24 mmOne eyepiece covers a wide focal length rangeStepless adjustment to ideal magnificationQuick adjustment of magnification without changing eyepiecesComfortable eye relief of 20 mm (LER = long eye relief)Adjustable rubber eyecup to adjust to ideal interpupillary distanceAlso very suitable for eyeglass wearersCompact and solid designMade entirely of black anodised aluminiumAluminium dust cap with threadVery high-quality material appearancePrecise and robust zoom adjustment mechanismRubberised grip surface for zoom adjustmentWhite laser engraving with focal length and pointer arrowFocal length range 8-24 mm freely adjustableOptical design: 9 lenses in 6 groupsAll lens surfaces have full multi-coatingEyepiece sleeve diameter: 1.25 inches / 31.7mmFilter thread in sleeve: M28 x 0.6 mm (standard 1.25'' filter thread)Eyepiece weight: 315 gLength of eyepiece: 102 mmDiameter: 52 mmColour: blackSCOPE OF DELIVERYDeluxe zoom eyepieceMetal dust cap for eyepiece lensPlastic dust cap for eyepiece sleeve

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)
