EXPLORE SCIENTIFIC 68° Ar Eyepiece 28mm (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.

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)

BRESSER 10mm Plössl eyepiece 31,7mm/1,25"
BRESSER 10mm 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.

Vixen SLV 50° Eyepiece 6mm (1.25'')
​The Vixen SLV series are the modern take on the classic Vixen Lanthanum eyepieces. These eyepieces were legendary for their generous eye relief and precise nature, making them a firm favourite with planetary, lunar and double star observers. This 6mm is an excellent choice for higher power on most telescopes, especially good for Lunar and Planetary observers. The SLV Series of Vixen Eyepieces feature a hexagonal shaped eyepiece barrel, long 20mm eye relief, and twist up click stop eyecup for adjusting to the most comfortable viewing. The SLV eyepieces feature high grade lanthanum glass, and deliver remarkably clear and high contrast star images to the edge of the viewing circle. The lenses are fully multicoated for high light transmission.Size 31.7mm/1.25"Apparent FOV 50°Eye relief 20mmWeight 168g (5.92oz)

EXPLORE SCIENTIFIC 100° Ar Eyepiece 9mm (2")
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 Argon-Purged Waterproof eyepiece is internally sealed and purged with inert, dry argon gas to prevent internal fogging, to halt the intrusion of fine particulates and fungus. This also maximizes 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.All 100° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.

EXPLORE SCIENTIFIC Filter Set 1 Moon & Planets from 50mm (2'')
Filter Set 1 is recommended for Moon & Planets from 50mm (2'') Aperture Set 1 includes the following filters: Explore Scientific Filter 1.25" Light Yellow No.8 - 0310268 Watching the Moon surface through the filter, the contrasts will enormously increase. Same with planet Mars. On the huge planet Jupiter, when using the filter, you can even see the contrasts between the cloud-bands and a lot more details. Starting with a telescope diameter of 8“ and a clear sight, you even get to see various details of Saturn. Explore Scientific Filter 1.25" Orange No.21 - 0310273 This one really supports the detection of the dark areas on the planet Mars. The details of the clouds of Saturn and Jupiter are also so much more visible through the Filter. Explore Scientific Filter 1.25" Blue No.80A - 0310264 The color of light blue really supports watching the high clouds on Mars. The contrast increases. The dark red structures will be shown even darker, so this is the perfect filter for watching the big red Flecks on the gas planet Jupiter. The rings of Saturn will be accentuated, the structures of the Venus Atmosphere will be even finer. EXPLORE SCIENTIFIC 1.25" Filter Grey ND0.9 - 0310245 The neutral density filter transmits light uniformly across the entire visual spectrum. It serves as an excellent filter to reduce glare and irradiation when observing the Moon with any telescope 4"(10.2cm) and larger. The ND96 filter may also be employed in the splitting of close double stars where one of the binary pair significantly exceeds the other in brightness. What ist a color Filter for and do we really need it? Color Filters darken the light slightly, that reaches the eye or the sensor of the camera. This eliminates for instance stronger transitions. The result is that your picture turns out with more contrast which automatically shows more details. FEATURES Made from high-quality optical glass Filter glass is absolutely parallel All optical surfaces have anti reflex coatings Filter housing from black anodized aluminum Filter threads on both ends (female/male) Multiple filters usage is possible SCOPE OF DELIVERY 4pcs color filter 4pcs protection-case
