Explore Scientific ASTRO R-LITE red light Flashlight
The ASTRO R-LITE red light flashlight is the ideal companion at night to read star charts or make adjustments to the equipment without losing the dark adaptation of the eyes. The ASTRO R-LITE offers 3 functions: Continuous light bright / Continuous light dark / Flashing. The large diffusing lens results in a very large and evenly illuminated light cone, which can also be adjusted by a sliding mechanism. By using a power-saving LED lamp, the battery life (1 x AA-LR6) is up to 100 hours. Of course, the robust lamp housing made of aluminium is splash-proof according to IPX4 and therefore particularly well suited for outdoor applications. The side cutouts on the front of the ASTRO R-LITE provide a 360° signal function. The 50 cm long carrying strap with quick coupling and an extra belt clip included in the scope of delivery ensure that the flashlight is always quickly at hand. The ASTRO R-LITE should not be missing in any equipment. FEATURES ASTRO R-LITE Red Light Flashlight Reading star maps at night Dark adaptation of the eyes is retained Continuous light bright / Continuous light dark / Flashing 360° signal function Large diffusing lens produces a uniformly illuminated light cone Carrying strap and belt clip included Battery life up to 100 hours - Battery (1 x AA-LR6) Splash-proof according to IPX4Robust lamp housing made of aluminiumSCOPE OF DELIVERYASTRO R-LITE Red Light Flashlight Carrying strap Belt clip Battery (1 x AA-LR6)

EXPLORE SCIENTIFIC TELRAD Projection Finder Scope with base
The TELRAD viewfinder is a projection finder that can be installed on any telescope and makes it child's play to align the telescope with the starry sky.The TELRAD viewfinder is a practical alternative to classic optical viewfinders and illuminated red dot viewfinders. You can see the complete starry sky without magnification, and not just a small section as with a normal optical viewfinder. Against this background of the starry sky, three red luminous concentric rings are projected, with apparent diameters of 4 degrees, 2° and 0.5° in the sky. Move the telescope so that the object you are looking for is in the inner ring, and the telescope points in the right direction. Because the object you are looking for is inside the ring, it will not be irradiated like a normal illuminated red dot finder.The base of the TELRAD viewfinder is self-adhesive and can be mounted on all telescopic tubes from about 10cm diameter. The length of the base is about 18cm. This base remains on the telescopic tube, the TELRAD viewfinder itself can be removed or attached at any time by means of the attached quick coupling. The TELRAD is powered by two normal AA batteries (not included).There are star atlases, like the "Deep Sky Travel Atlas" from Oculum-Verlag, and planetarium programs for the PC, like the program "Stellarium", where the three rings of the TELRAD are already drawn or can be displayed around the interesting celestial objects. This makes finding these celestial objects a real walk.FEATURESTELRAD projection finderIlluminated rings of 4 degrees, 2° and 0.5° in the skySee the complete starry sky without magnificationEasy installation and useCan be installed on nearly every telescopesBase with quick release coupling included Powered by two AA batteries (not included) Very long battery life because of LED technologySCOPE OF DELIVERYTELRAD viewfinder with projector and battery compartment TELRAD base with quick-release coupling for the viewfinder Adhesive tape for attachment to telescope

EXPLORE SCIENTIFIC 2" CLS Nebula Filter
Besides air turbulence, the brightening of the night sky is the biggest obstacle to observing faint objects beyond the solar system. Street lamps and other artificial lighting mean that the sky in human settlements is no longer really black. This affects the contrast and thus the perception of deep-sky objects. Depending on the type of celestial object, however, part of disturbing artificial light can be filtered out, making it easier to observe fainter targets.The EXPLORE SCIENTIFIC CITY LIGHT SUPRESSION - or CLS - filter uses the fact that the artificial lighting is not evenly distributed over the entire spectrum. These colours - in the case of the EXPLORE SCIENTIFIC CLS nebula filter, above all the typical colours of mercury and high-pressure lamps, used in street lighting - are suppressed, but the emissions of deep-sky objects are allowed through. With a slightly brightened sky, some relatively bright deep-sky objects are practically invisible with a telescope, for example the large galaxy M101. Using this filter makes observation much easier. A must have for any visual amateur astronomer.  The CLS can also be used as a useful photographic filter - helping to improve the quality of your telescopic deep sky photos.The EXPLORE SCIENTIFIC nebula filters are delivered with an individual test report - so you can be sure of receiving high-quality filters.SPECIFICATIONS:eliminates disturbing light - e.g. from street lightingenables observation of faint deep sky objectsWHAT'S INCLUDED:1x nebula filter

EXPLORE SCIENTIFIC 82° Ar Eyepiece 11mm (1,25")
Explore Scientific 82° Series™ extreme wide field eyepieces are optimized to produce high contrast, high resolution, and superior flat field characteristics. The visual effect of these 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 a twist-up rubber eye-guard that raise to the desired height for the comfort of the observer, and 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. All 82° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.

EXPLORE SCIENTIFIC 1.25" UHC Nebula Filter
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 UHC filter uses a characteristic property of the so called emission nebulae. Those objects glow in special colours, their emission lines. Those emission lines are linked to chemical elements - in this case hydrogen at 486nm and 656nm, plus oxygen at 496nm and 501nm. The Explore Scientific UHC nebula filter blocks all other colours (and thereby nearly all of the artificial light) and only the emission line of the hydrogen and 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 Owl-nebula M97, the Veil-nebula NGC6992 or even the bright Dumbell-nebula M27 are not clearly visible. By using this filter you can see the nebulae and their structures without problems. A must for every visual observer.

EXPLORE SCIENTIFIC 68° Ar Eyepiece 16mm (1,25")
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.
