BRESSER 40mm 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. FEATURES Focal length: 40 mm Field of view: 46° Lens-Design: 4 lenses in 2 groups , fully-multicoated Housing material: completely made from metal Rubber eyecup: YES, foldable Filter thread: YES Storage: Twist-pack SCOPE OF DELIVERY BRESSER Plössl eyepiece with rubber eyecup Twist-pack

The visual effect of these new 8,5mm 82° LER 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 foldable eyecups make handling and using in the field easy. 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.These eyepieces are the choice for observers wearing glasses - with excellent performance and durability. 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.Comfort, Quality, Value. The Explore Scientific 82° LER Series Most short focal length eyepieces are excellent flat-field multi-element oculars that can transform your visual astronomy experience.

The BRESSER First Light AR-102/1000 telescope is ideal for both ambitious beginners and experienced astronomers. Discover the stunning features of Orion Nebula, which is located at a distance of 1500 light years (14,200,000,000,000 km) from earth! The stable mount keeps the telescope stable, even at higher magnifications. Thanks to the high-quality mechanics, you can take your own photos of the moon and marvel at the dividing line between night and day (terminator). The refractor telescope features an equatorial mount (also called a parallactic mount). Thanks to this two-axis mechanism, it is possible to compensate for the rotation of the earth, enabling you to precisely track your desired celestial object. The telescope also comes with a wide range of accessories for exploring the night sky, including a prism for an upright and laterally correct image.

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 systems enourmously. Depending on the type of the celestial object it is possible to increase the contrast dramatically by blocking the annoying artifical light. The EXPLORE SCIENTIFIC O-III filter uses a characteristic property of the so called emmission nebulae. Those objekcts glow in special colors, the so called emmission lines. Those emmission lines are linked to chemical elements - in this case oxygen. The EXPLORE SCIENTIFIC O-III nebula filter blocks all other colors (and thereby nearly all of the artificial light) and only the two emmission lines of the oxygen can pass the filter. The result is astonoishing: suddenly nebulae are visible at locations that were completely empty without filters. In suburbian skies for example the veil nebula NGC 6992 is almost not visible with a 200mm telescope. By using this filter you can see the nebula and its structures without problems. A must for every visual observer. The EXPLORE SCIENTIFIC nebula filters come with a individual test certificate - your guarantee to receive a premium filter.FEATURESenables the observation of so called emmission nebulaeblocks almost the entire artificial lightonly the two emmission lines of the oxygen passes the filterSCOPE OF DELIVERY1x 1,25" O-III nebula filter
