EXPLORE SCIENTIFIC Light Shroud 10" + 12" Ultra Light Dobson

Keep out stray and unwanted light from your 16" Truss Tube Dobsonian telescope with a lightweight light shroud. Keeping the path dark between your secondary and primary mirror will boost image contrast and brightness bringing out more details. Constructed of opaque black nylon with excellent stretch, each end of our DOB light shroud has an elastic band to keep the shroud in place and allow for an easy fit and installation. Breathable nylon will let air circulate and yet keep dust away, keeping your optics clear and avoiding any unnecessary pressure from the breeze. A must have for the suburban observer where stray light interferes.FEATURESKeep out stray and unwanted light Boost image contrast and brightnessBringing out more details Keep dust away; avoiding pressure from the breezeBlack nylon with excellent stretch Fits for 16" Truss Tube Dobsonian telescopeSCOPE OF DELIVERY1 pc Light Shroud 16"

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

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

An optimal set for ambitious astrophotographers: the BRESSER Messier NT203s/800 Telescope with EXOS-2 PMC-Eight GoTo Mount. With its short f/3.9 focal ratio, this 203-mm telescope with a parabolic primary mirror allows deep sky imaging with short exposure times. The large 85 mm secondary mirror ensures optimal field illumination, while the high-quality 2.5" Hexafoc focuser enables vignetting-free photography. The modern mount impresses with its precise GoTo control and easy operation via the ExploreStars app, ensuring accurate tracking and intuitive sky navigation. The Telescope The BRESSER Messier Newton Telescopes have established themselves as reliable workhorses for astrophotography in recent years. With the Messier NT203s/800 with Hexafoc, we present the latest generation of these devices. The photo-Newton with a parabolic primary mirror and a fast focal ratio of 203 mm (8") f/3.9 enables deeper exposures in the same amount of time. The large 85 mm secondary mirror guarantees optimal field illumination, and the high-quality 2.5" Hexafoc focuser ensures vignetting-free photography. The tube rings with a 44-mm universal dovetail bar and handle with camera mounting option, along with an excellent bright crosshair finder, round out this high-quality device.The focuser can also be upgraded with a 10:1 reduction gear (Art. No.: 0625720). For pinpoint star imaging, the optional HR Coma Corrector (Art. No. 0510330) can be used. This is designed for both visual and photographic use, significantly improving image quality, especially in the outer areas of the field. 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 are directly connected to this unit via cable, and a ST-4 compatible autoguider port is also available. The control system also supports micro-step operation to ensure precise tracking. Intuitive operation via app and graphical star map The ExploreStars app, specifically developed for the PMC-Eight system, impresses with its well-designed, intuitive graphical interface. The current alignment stars for control initialization, as well as all celestial objects in the database, are displayed 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 heart 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 allows remote operation via browser, ASCOM, app, or serial connection. With Open GoTo, custom firmware can also be written and loaded into the controller unit, allowing customization of device functions and the creation of custom object lists, etc. Polar finder included The included and pre-installed polar finder scope enables quick and precise polar alignment for long exposure times without unwanted star trails. The integrated LED lighting unit further enhances the user experience of the polar finder.
