These eyepieces with their huge apparent field of view not only gave the observer a panoramic visual experience, but they relax the eye so the observer could pay attention to subtle details for extended periods. These ultra-wide angle eyepieces played a critical role in the military for aiming at targets, and their long eye-relief counterparts helped reduce eye injury from recoil. Each 100° Series Nitrogen-Purged Waterproof eyepiece is internally sealed and purged with inert, dry nitrogen gas to prevent internal fogging, to halt the intrusion of fine particulates and fungus, and to maximize the life of the internal coatings. To make sure, every 100° eyepiece is tested by submerging them down to 1 meter of water for 30 minutes.

Warning notes
  • General safety instructions DANGER Risk of eye injuries! Never look directly at the sun or near the sun through this device. There is a risk of blindness! Children should only use the device under supervision. Keep packaging materials (plastic bags, rubber bands, etc.) away from children! There is a risk of suffocation! FIRE HAZARD! Do not expose the device – especially the lenses – to direct sunlight! The light concentration could cause fires. RISK of material damage! Do not dismantle the device! In case of a defect, please contact your dealer. They will contact the service center and may send the device in for repair. Do not expose the device to temperatures above 60°C!
  • Never look at the sun through an eyepiece/telescope without a certified protection filter. A moon filter can never be used for solar observation. The moon filter is only suitable for moon observation. The solar filter must be mounted in front of the telescope opening, not at the eyepiece. Otherwise, the concentrated light beam through the optics will immediately destroy the filter foil, leading to severe eye damage, including permanent blindness.
  • Never leave the optics unattended. Children and inexperienced adults could point the telescope at the sun without proper precautions and lose their eyesight.
  • Do not expose the device to high temperatures.

BRESSER Barlow Lens 2x 31.8mm/1.25"
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)

EXPLORE SCIENTIFIC ED APO 127mm f/7,5 FCD-100 Alu HEX
Highly corrected 127 mm air-spaced triplet apochromat (with three lenses) and aluminium tube and a 2.5'' high-precision HEXAFOC focuser. NEW: Now with hybrid viewfinder shoe to accept different viewfinder holders. Apochromats are the ultimate choice in small to medium-sized telescopes: the combination of compactness, transportability, very high image contrast and sharpness together with the possibility to make excellent astrophotos cannot be bested. The advances in glass manufacturing during the last few years have made true apochromats available to more astronomy enthusiasts than ever before. The new Explore Scientific FCD-100 Alu Hex represents another major improvement in this field - the overall correction (colour and spherical) is setting new standards in this price class. The optical design shows a polystrehl value of 0.97 indicating a level of correction that is absolutely top of the line. This excellent apochromat is a very versatile telescope: the fast f-ratio makes short exposure times possible. The high contrast and sharpness of the image provide breathtaking views of large objects like the North America nebula or the Andromeda Galaxy, as well as tack sharp planetary images. The telescope is lightweight and compact - the dew shield slides down the tube to minimize size for transportation. Revolutionary glass and precision manufacturing created a telescope that offers observing joy on the highest level. This does not only qualify this telescope as the ideal travel scope, it is also the perfect choice for fast observations and for astrophotography. The excellent 2,5'' HEXAFOC focuser with 10:1 reduction is perfect for this - the large inner diameter of 65 mm prevents vignetting by the focuser when the telescope is used for astrophotography with large sensors. These very popular EXPLORE SCIENTIFIC Triplet ED APO Refractors we do offer in 3 different product lines: Essential Line: HOYA FCD-1 Glass lens, AL-Tube, 2.0'' Rack and Pinion Focusser with 1:10, 2.0'' Star Diagonal 99% Reflectivity (see Part No. 0112084(AL), 0112106(AL), 0112132(AL)), 0112155(CF + 3''FT) Professional Line: HOYA FCD-100 Glass lens, AL/CF-Tube, 2.5'' HEXAFOC Focusser with 1:10, 2.0'' Star Diagonal 99% Reflectivity (see Part No. 0112086(AL), 0112108(AL), 0112109(CF), 0112134(AL), 0112135(CF)) High-End Line: OHARA FPL-53 Glass lens, Carbon(CF) Tube, 3.0'' Feather-Touch Focusser with 1:10, 2.0'' Star Diagonal 99% Reflectivity (see Part No. 0112165(CF)) SPECIFICATIONS Aperture: 127 mm Focal Length: 952 mm Focal ratio: f/7.5 Design: Apochromat with three lenses, two air spaces and FCD-100 glass Weight: 7.7 kg Back focus: 150 mm above 2'' adaptor Hybrid viewfinder shoe to accept different viewfinder holders SCOPE OF DELIVERY Optical tube with retractable dew-shield 2.5'' HEX focuser with 1:10 gear reduction 2'' Star Diagonal 99% reflectivity Tube rings with dovetail plate and handle Dust caps for front-lens and focuser Hybrid viewfinder shoe

EXPLORE SCIENTIFIC 68° Ar Eyepiece 40mm (2")
With the introduction of the 68° Series we are pleased to make two important improvements in eyepiece manufacture, the first being 15 layer Enhanced Multi-layer Deposition (EMD™) coatings on all glass-to-air surfaces to gain maximum contrast, and waterproofing the eyepiece with the use of Argon gas purging instead of standard Nitrogen gas. Although Nitrogen is a fine choice that will last for many years, Argon is a larger molecule that maintains its protective properties over a wider range of temperatures, and is even more resistant to diffusion thereby further extending the protective waterproof environment of the eyepiece body. Through computer-optimized design, a careful selection of optical glasses, and enhanced multi-layer deposition coatings, the Explore Scientific 68° Series™ eyepieces produce long eye-relief and ensure high image-correction, a flat field, and high contrast across the entire image field. An excellent choice for those who make extended visual studies of detail with subtle variations of brightness, and for those who must wear glasses while observing. All 68° Series eyepieces are fully EMD (Enhanced Multi-Layer Deposition) coated and edge-blackened to produce superior contrast.

EXPLORE SCIENTIFIC Ultra Light Dobsonian 305mm GENERATION II
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
