Product information "LUNT LS7-21ZE Zoom Eyepiece 7.2mm - 21.5mm"
Lunt Solar Systems zoom-eyepiece with variable focal length from 7.2mm to 21.5mm, with 1.25 inch (31.7mm) connection.

The special of this zoom eyepiece is that the optical layout offers highest quality views of the sun, but also on nightsky objects. LUNT minimized the reflections by using superb multicoatings and with care designed internal baffle system and blackened lens edges. The LUNT zoom-eyepiece is not the widest field zoom-eyepiece on the market, LUNT prefered best performance over widest field. The sun and stars are perfect pin point across the entire field of view without any visible distortion. The LUNT zoom-eyepiece is almost parfocal, from one end to the other end of the zooming way you need only 0.5mm to refocuse. The LUNT zoom-eyepiece has a very nice height adjustable eyeguard to protect your eye against day light reflections and to help you to find the perfect eye position.

Please note that these eyepieces are only accessories for existing solar telescopes or filters when observing the sun. Solar observation alone with these eyepieces without additional solar filters is not possible!

LUNT Sol Searcher
Sol-Searcher for installing on all solar telescopes of Lunt Solar Systems. The tube rings of the LUNT solar telescopes are prepared for the mounting of this Sol-Searcher."I can't find the Sun!" sounds funny. However, the Sun is tricky to find in a properly filtered telescope, and you don't ever want to chance a direct gaze, let alone a magnified image of it.This Sol-Searcher is the safe and easy way to find the Sun. It is absolutely safe since you don't look through Sol-Searcher, you look at it. The aperture acts as a "pinhole" which projects an image of the Sun on to the 1/4" translucent "screen." This screen can be viewed from either side. Simply move your scope until the Sun's image is centered on the screen and the Sun will be in the eyepiece's field of view.The solar telescopes from Lunt Solar Systems are fitted for installing this Sol-Searcher. Only at the LS130MT and LS152THa telescopes the additionally adapter 0554302 will be needed.SCOPE OF DELIVERYTeleVue Sol-SearcherScrewsHexagon wrench

EXPLORE SCIENTIFIC 2" 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 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

EXPLORE SCIENTIFIC 2" Variable Polarizing Filter
Universally usable variable polarizing filter with a  2" filter thread.This variable polarizing filter allows for a continuous adjustment of the image brightness. This is very helpful to level strong differences in contrast of different observation objects individually. Particularly for lunar and planetary observations but also for solar observations this filter prevents an outshining of details.Solar observations ONLY together with an adequate solar filter !!! Particularly when a Herschel wedge is used and with large objective lens apertures the use of the variable polarizing filter can reduce the brightness of the observation object to a confortable level. The large adjustment range of 40% to 1% light transmission and the neutral grey filter effect create a comfortable and unadulterated image.The handling is very simple. The desired filtering level is set by turning the two sides of the housing against each other.A 2.0" filter thread on both sides (female/male) allow for the simultaneous use of additional colour filters.FEATURESvariable polarizing filterindividually adjustable image brightnessmade from high-quality optical glassblack anodized aluminium housing2.0" filter thread on both sidesSCOPE OF DELIVERYpolarizing filterprotective box

EXPLORE SCIENTIFIC 68° Ar Eyepiece 20mm (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.

EXPLORE SCIENTIFIC 100° Ar Eyepiece 5,5mm (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.

BRESSER BinoViewer Deluxe 1.25''
You see better with two eyesThe BRESSER BinoViewer Deluxe makes it possible to observe astronomical objects in a relaxed way with both eyes and with considerably more detail than using one eye. The images created of the moon, planets and globular clusters are particularly impressive. But also with deep-sky objects such as the Orion Nebula the detection of details is much easier. At the same time this binoviewer is very easy to handle. Thanks to the newly patented optical system you can get into focus with any telescope. All you need is a pair of identical eyepieces to enjoy this dramatic and immersive viewing experience.How to use the BinoViewer? Since the BRESSER BinoViewer Deluxe does not require an additional light path (back focus), it can be used with any telescope - including Newtonians and short focus refracting telescopes, which traditionally suffered when using standard binoviewers. No light path corrector or similar accessory is necessary. If a standard 1.25'' eyepiece can be focused, the binoviewer will also work. The eyepiece focal length and field of view size of the eyepieces used are fully retained. As with binoculars one eyepiece is focused first using the telescope focuser. Then the second eyepiece can be brought into focus using the helical focuser on the binoviewer. The required interpupillary distance is then elegantly adjusted to a range of 58–74mm with the help of a linear sliding mechanism, with graduated marker, to help you find your ideal interocular setting quickly.  Self-centring helical eyepiece grips, rather than side-mounted thumbscrew eyepiece retainers are used, decreasing the chance of offsetting collimation of both eyepiece to each other.  The fact that this design of binoviewer uses a well-engineered linear slide mechanism to adjust interpupillary distance, rather than a cheaper-to-produce traditional hinged design also helps retention of collimation.Which objects can be observed with this accessory?Actually, all objects that were previously observed with the telescope in question, but only monocularly with one eye. Because there is no magnification factor at the binoviewer, even low magnifications can be achieved. This makes not only the moon, planets and globular clusters, but also the brighter deep-sky objects very interesting observation targets. The use of two eyes leads to a more relaxed view than using one eye alone.  Although true depth of field viewing at infinity is a little beyond most telescopes and binoviewers, users will note how the human brain attempts to impose depth of field ("3d-like") effects on stereo views through binoviewers.  The biggest difference that most observers comment upon when comparing views through binoviewers like these, as opposed to single monocular eyepiece views, is the extra detail that can be seen in most observable targets.  Relaxed viewing and extra detail in objects are the two main benefits of binoviewing, which the BRESSER Bino Viewer Deluxe 1.25'' delivers in abundance.Also ideal as an accessory for solar telescopesA very special application is the use of the BRESSER BinoViewer Deluxe in combination with all solar telescopes. The spherical shape of the sun with all its surface details is shown very impressively.  The depth of field effects of seeing filaments silhouetted against the solar surface are particularly enjoyable to observe.Important note: Do not use the BRESSER Binoviwer Deluxe without a suitable solar telescope or a safe solar filter in front of the telescopes objective lens . Otherwise, there is an acute risk of going blind.High-quality mechanics and materialsThe entire BRESSER BinoViewer Deluxe is made of high-quality materials. Except for the outer plastic covers all components are made of anodised aluminium. Particularly remarkable are the low-backlash sliding mechanism for adjusting the interpupillary distance and the precise rotary clamping of both eyepiece adapters. The wide clamping surface holds the eyepieces in place securely and also centres them automatically on the optical axis. The one-sided dioptric adjustment has a backlash-free helical drive and enables the finest corrections. For safe transport a high-quality hard-shell transport case is included in the scope of delivery.Which eyepieces can be used?All eyepieces with a 1.25'' barrel and a field stop of up to 22mm. Depending on the interpupillary distance the outer diameter of the eyepiece housing should not exceed a value of approximately 50 mm.Filter thread 1.25'' availableNo 2nd filter sets are necessary to operate the BRESSER Binocular Approach Deluxe. The desired colour or nebula filter can be screwed directly into the 1.25'' nosepiece. in this configuration, when changing the eyepieces to affect a change in magnification, no swapping of filters is necessary.  Unique mirror-lens system with Ohara (Japan) lanthanum glass material The BRESSER Binocular Viewer Deluxe is equipped with a unique mirror-lens system. This has the advantage of higher light transmission and less color aberration. The resulting image is simply brighter and sharper. To achieve this the exclusive Ohara (Japan) lanthanum glass material has been used and in addition all optical surfaces are equipped with a full multi-layer broadband coating. Finally the beam-splitting mirror has a 99% dielectric coating and completes the excellent optical design.FEATURESEnables binocular observations with all telescopesRelaxed and comfortable viewingThree-dimensional viewing experienceSuitable for all telescopes with 1.25'' eyepiece connectionNo additional light path requiredNo magnification factor at the binocular attachmentEven low magnifications with large fields of view are achievableFor observing moon, planets and deep sky objectsPrecise and robust mechanicsSliding mechanism to adjust the interpupillary distanceDioptric compensation via fine helical driveWide eyepiece rotation clamp with automatic centeringFilter thread 1.25'' (M28.5 x 0.6mm) availableLens and mirror design made of finest Ohara (Japan) lanthanum glass materialAdvanced broadband multilayer coating on all optical surfaces99 % dielectric-coated beam-splitting mirrorHigh-quality hard-shell carrying case includedWHAT'S INCLUDEDBino Viewer DeluxeDust capsCarrying case

EXPLORE SCIENTIFIC 100° Ar Eyepiece 14mm (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.
