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 enormously. Depending on the type of the celestial object it is possible to increase the contrast dramatically by blocking the annoying artificial light. The EXPLORE SCIENTIFIC O-III filter uses a characteristic property of the so called emission nebulae. Those objects glow in special colours, the so called emission lines. Those emission lines are linked to chemical elements - in this case oxygen. The EXPLORE SCIENTIFIC O-III nebula filter blocks all other colours (and thereby nearly all of the artificial light) and only the two emission lines of the oxygen can pass the filter. The result is astonishing: suddenly nebulae are visible at locations that were completely empty without filters. In suburban 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 emission nebulaeblocks almost the entire artificial lightonly the two emission lines of ionised oxygen passes the filterWHAT'S INCLUDED1x 2" O-III nebula filter

Whether you want to explore the night sky or make terrestrial observations during the day, the BRESSER NightExplorer 15x70 astronomy binoculars will ensure that you are perfectly equipped for all your outdoor adventures. The extra large lens diameter of 70 mm lets a large amount of light into the binoculars, while the 15x magnification ensures that you obtain highly detailed images of your observed targets. Fully multicoated optics ensure scattered light is kept to a minimum, so that you can enjoy a perfect view with the best possible optical performance. At a distance of 1000 metres, the field of view is 77 metres wide. The highly corrected eyepieces with 5 lenses in 3 groups produce vivid images with sharp edges. Coating The premium BaK-4 optics (barium crown glass) features a full multi-coating to increase light transmission and reduce reflections. Focusing Thanks to the individual eyepiece adjustment, you only need to focus the binoculars once. You can then enjoy a sharp image at infinity for the night sky. The binoculars also have a close focus, which you can set from a distance of 10 metres or more for close-up observations of your immediate surroundings. Also suitable for glasses wearers Thanks to the foldable eyecups, you can set the optimal distance between your eyes and the ocular lenses. If you wear glasses, this allows you to see the entire field of view of the Porro-prism binoculars. There is also a dioptre compensation of +/-8, which you can use to compensate for small differences in vision between your eyes. Weatherproof and robust Thanks to their waterproof design, the binoculars can be used in wet or foggy weather conditions, as water and moisture cannot enter the housing. The binoculars are filled with argon to stop the optics from fogging up. In addition, the ergonomic armouring provides a secure grip and protects the binoculars against impacts and knocks, making them ideal to travel with. Portable design The 15x70 Porro-prism binoculars come with an excellent lightweight aluminium tripod, with study ballhead mounting, to ensure wobble-free astronomical or terrestrial observations. Both the binoculars and the tripod can be stored in the sturdy padded backpack, which is also included in the set. This ensures that you can easily transport your gear to your desired vantage point, even if you have to go a long way to get there.

Ultra Light Dobsonian 305mm GENERATION II - with completely redesigned and improved construction.No telescope type has influenced amateur astronomy as radically as the dobsonian telescope. Before the introduction of this telescope type by John Dobson the vast majority of amateur telescopes were small inadequate refractors on shaky mounts - just good enough to show the polar regions on mars or the rings of Saturn. Bigger telescopes, like the Schmidt-Cassegrain telescopes, were restricted to the relatively small group of amateurs that could afford them.The brilliant combination of simple - but effective - mechanics and the largest aperture available led to a worldwide triumph of this concept. No other telescope type offers you so much light for your money as a good dobson. We have taken the motto "held together by gravity and driven by yoghurt power" and offer a modern version of the classic - designed by amateur astronomers for amateur astronomers. Despite its large aperture the telescope can be transported easily even in small cars and is assembled within minutes without tools. The construction was optimized for maximum rigidity with a minimum of mass. The combination of big altitude wheels and a optimized aluminium-sandwich construction allows for small movements even at high magnifications. The focus position is already positioned to accept our coma-corrector. The ideal workhorse for the deep-sky enthusiast. A telescope with 305mm aperture gathers more than 1800-times more light than the naked eye. Details on planetary surfaces stand out even to unexperienced observers, and countless deep-sky objects show details. Bright globular clusters are resolved down to the core and the view of the lunar terminator will provide a unforgettable experience.Dimensions for mobile use: Rockerbox 450mmx450mmx320mm; Mirrorbox 380mmx380mmx300mm; Trusses approx. 980mmEyepiece Height while pointing at zenith approximately 1,4m.12“ Net total weight: 32,1 kg; 12“ Mirror Box: 18,9 kg; 12“ Secondary cage +Rockerbox: 10 kg; 12“ 4 Pairs of trusses: 1,8kg; 12“ Altitude Wheels: 1,4kg ; Focuser thread: M54 x 0.75 mm ; Backfocus: 45mm behind the 2" eyepiece holder. 35mm when the 1.25" adapter is mountedSPECIFICATIONS Truss-Dobsonian Telescope in full Aluminium constructionNEW: Slider bearings made from TEFLON und GFK for smooth and precise movementNEW: Improved main mirror cell with completely redesigned mechanicsNEW: Altitude bearings with new designed brake and friction systemNEW: Larger feet to improve stabilityNEW: Universal finder slot to enable an easy finder upgradeNEW: Counter-weight system included - 2 x 1.0 kg NEW: Quick-lock fasteners with new springloaded design for comfortable useNEW: Powder-coated yellow altitude wheels to improve durabilityNEW: Laser engraved central mark on main mirrorSCOPE OF DELIVERYTruss Dobsonian TelescopeLED finder with standard finder slotStray light shield for secondary cageMain mirror collimation toolBattery compartment with bag for fansCounter-weights 2 x 1.0 kgExtension tube for focuserReducer 2"/1.25"Manual
