Product information "BRESSER LER Zoom Eyepiece 8-24mm 1.25''"
One eyepiece for every occasion
The BRESSER zoom eyepiece covers the large focal length range from 8 to 24 mm. These are also the focal lengths most frequently used with most telescopes. Especially for instant observations, where you don't want to pack a whole suitcase full of eyepieces, the zoom eyepiece is a good choice.

Always the ideal magnification on hand
A quick turn and the ideal magnification for you is set. The adjustment is stepless from 8 to 24 mm focal length. This eliminates the need to always change eyepieces.

Comfortable viewing
The BRESSER zoom eyepiece offers a large comfortable eye relief of 20 mm to the eyepiece lens (LER = long eye relief). This means comfortable viewing even during longer observation, an important criterion especially for people with glasses. The rubber eyecup can also be individually adjusted by a twist and turn movement. Apparent field of view is 40 up to 56 degrees which offers a good overview.

Advanced optical design
To achieve the best possible image over the entire focal length range, a sophisticated optical design with 8 lenses in 5 groups is used. The full multi-coating on all lens surfaces also guarantees maximum light transmission. To effectively suppress unwanted reflections, all lenses are carefully blackened at the edges. Thus, the image produced offers the maximum possible contrast and image brightness.

Compact and solid design
The BRESSER zoom eyepiece is made entirely of black anodised aluminium. It has an extremely solid and high-quality material appearance and is long-lived even with extensive use. The precise zoom mechanism can be operated safely through the ribbed metal adjustment ring. A white laser engraving with focal length and pointer arrow indicates the currently set focal length even in low light.

EXPLORE SCIENTIFIC 1.25" O-III 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 enourmously. Depending on the type of the celestial object it is possible to increase the contrast dramatically by blocking the annoying artifical light. The EXPLORE SCIENTIFIC O-III filter uses a characteristic property of the so called emmission nebulae. Those objekcts glow in special colors, the so called emmission lines. Those emmission lines are linked to chemical elements - in this case oxygen. The EXPLORE SCIENTIFIC O-III nebula filter blocks all other colors (and thereby nearly all of the artificial light) and only the two emmission lines of the oxygen can pass the filter. The result is astonoishing: suddenly nebulae are visible at locations that were completely empty without filters. In suburbian 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 emmission nebulaeblocks almost the entire artificial lightonly the two emmission lines of the oxygen passes the filterSCOPE OF DELIVERY1x 1,25" O-III nebula filter

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.

EXPLORE SCIENTIFIC 1.25" 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 EXPLORE SCIENTIFIC 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 CLS filter

EXPLORE SCIENTIFIC OPTOLONG 1.25" L-Pro Deep-Sky Light Pollution Filter
LPS filter L-Pro for deep sky nebula constellation photography.The relentless spread or urbanization and its associated light pollution have become a growing problem for all amateur astro photographers. The current solutions to the problem can be expensive and might include the purchase of a monochrome camera, several types of narrowband filters and a filter wheel. Especially with inexpensive newtonian telescopes, double-lens ED refractors or even achromats, the L-Pro filters open up completely new possibilities for the capture of high-class astronomical images even out of the light polluted city. CMOS cameras can deliver images like monochrome cameras. This new generation of filters makes it possible to take amazing astrophotos directly from the light-polluted city with all its artificial light sources. L-Pro is a multi-bandpass filter which offers better color balance by maximizing the transmission band. The balanced transmission allows astrophotos to be taken with minimal color cast to broadband emission objects such as galaxies, reflection nebulae and globular star clusters. L-Pro is the best choice for light pollution suppression. L-Pro description L-Pro (L-Professional) filter is designed to improve the visibility of various deepsky objects. By selectively reducing the transmission of wavelengths of light pollutants, specifically those produced by artificial lightings including mercury vapor lamps, both high & low pressure sodium vapor lights and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. skyglow). Together with the highly transparent in main nebula emission lines at OIII (496nm and 500nm), H-beta (486nm), NII (654nm and 658nm), H-alpha (656nm) as well as SII (672nm), the filter is suitable for enhancing the contrast and details for both visual and photograghic purpose at sub-rural areas with heavy light pollution. L-Pro is a multi-bandpass filter which offers better color balance by maximizing the transmission band. The balanced transmission allows astrophotos to be taken with minimal color cast to broadband emission objects such as galaxies, reflection nebulae and globular star clusters. L-Pro is the best choice for light pollution suppression. Main use and performance Suitable for visual observation and astrophotography. L-Pro filter has a very low transmission reduction rate against continuous spectrum space objects, and thus is quite effective in suppressing light pollution sources when shooting galaxies, reflection nebulae and globular star clusters. The same holds true for visual star observations. L-Pro filter alone can suppress infrared wavelength, and thus can be used at ease for ''L'' image shootings with CCDs. Light pollution filters do not eliminate the effects of light pollution or increase the object’s brightness. In many cases, they increase the contrast between nebula and night sky, not brightening the nebula. WARNING: These nebula filters are not designed for sun observation. DO NOT LOOK AT THE SUN WITH THIS FILTER. You will go BLIND if you ignore this warning.Coating technology L-Pro has a multiple anti-reflective coating on the optical substrate. The L-Pro filter uses a precision coating based on ion deposition coating technology. This ensures durability and scratch resistance as well as stability on the CWL (central wavelength), which is not affected by temperature changes. Absolute precision and homogeneity of the coatings as well as maximum values for transmission in the passband and optical density in the off-band range are guaranteed for all filters.FEATURES Professional visual and photographic filter for astronomy Improves deep sky nebula constellation photography Best choice for broadband light pollution suppressionFilter diameter: 1.25 inch / 31.7mm Connecting thread: M28.5 x 0.6mm (Eyepiece thread 1.25 inch)Selected optical glass material Spectrum: 380-750nmSurface Quality: 60/40 (Refer to MIL-O-13830) Fine-optically polished glass to ensure accurate 1/4 wavefront and highest parallelism over the both surfaces High transmission at major nebula emission lines (i.e. H-alpha 656nm, OIII 496nm&500nm, SII 672nm and H-beta 486nm)Precision off-band blocking, specifically the major emission lines of artificial light pollution (i.e. Na 589nm, Hg 435nm and 578nm)SCOPE OF DELIVERY L-Pro filter (1pc) Dust protection box (1pc)

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.

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.
