EXPLORE SCIENTIFIC BT-120 SF Giant Binocular with 62° LER Eyepieces 20mm
Giant binocular for observing the starry sky, nature and landscape. Observe the beauty of the starry sky at night and distant objects in nature during the day. Globular star clusters, glowing gas nebulae, the moon with its craters and even planets can be observed wonderfully on a clear night. But also all other distant things in nature and landscape, even ships and airplanes can be seen in detail. With the all-round binoculars of the EXPLORE SCIENTIFIC BT series, you can get up very close. Thanks to the large, light-gathering lenses and the professional coatings on all lens surfaces, these binoculars produce bright and brilliant images even at night and at twilight, providing a special viewing pleasure. The comfortable 45 degree viewing angle allows fatigue-free use, even when the binoculars are tilted upwards towards the zenith.  A large binocular can also be called a double refractor telescope Binoculars such as these can really be described as a double telescope.  In this configuration, the full light gathering power of one single telescope is available to each eye. Experience a whole new dimension of observing as a consequence. Objects are reproduced almost vividly in these binoculars and observing with both eyes is a very relaxing experience. Last but not least, this comfortable way of observation increases the recognition of the finest details (particularly in fainter deep sky targets) and effectively prevents eye fatigue. Extremely robust binoculars with magnesium housing, sealed and filled with nitrogen  The BT series binoculars are designed for tough outdoor use. The IPX6 sealed and nitrogen-filled design effectively prevents fogging of the internal optics even under difficult weather conditions. The very light magnesium housing saves weight and makes it easy to handle. Two EXPLORE SCIENTIFIC 20mm eyepieces of the 62 degree LER series already included. EXPLORE SCIENTIFIC is an established manufacturer of extremely high-quality eyepieces in the astronomy scene. An optical system is only as good as its weakest component. Therefore we have decided to deliver these giant binoculars with a pair of quality eyepieces of the 62 degree LER series. With an apparent field of view of 62 degrees and a focal length of 20mm, the BT-120 binoculars produce a 33x magnification. Thus these wide angle eyepieces offer a very good overview (field of view 1.8 degrees) at moderate magnification. The large interpupillary distance of these LER (long eye relief) eyepieces of 15mm and soft silicone eyecups, which can be turned inside out, also guarantee a comfortable and relaxed view. For astronomy, a flat and sharp image field is advantageous and offers a particularly impressive viewing experience even during the day. Due to the waterproof design and the argon filling, these eyepieces are absolutely durable and easy to clean. Interchangeable eyepieces with 1.25 inch / 31.7mm plug-in diameter Adjust the magnification and field of view to your individual needs and choose from a wide range of available eyepieces. All eyepiece types with a plug-in diameter of 1.25 inch / 31.7mm can be used with the binoculars of the BT series. Especially recommended are EXPLORE SCIENTIFIC eyepieces of the 62 and 82 degree series with focal lengths from 8 to 26mm (see item No. 02188xx and 02196xx). The magnification can be varied from 25x to 75x (focal length binoculars : focal length eyepiece = magnification). The eyepieces are held in the binoculars by a precise brass compression ring clamp and guarantee a tilt free position.  Use of colour and nebula filters for astronomical observations Increase the contrast and visibility of objects and details by screwing the corresponding filters directly into the thread of the eyepiece sleeves. The use of colour and nebula filters must of course always be done in pairs. Suitable are all EXPLORE SCIENTIFIC screw filters with 1.25inch / 31.7mm diameter (see item No. 03102xx)  Comfortable 45 degree view and helical single focus The 45-degree viewing angle allows a relaxed observation position even when the binoculars are tilted strongly. Also the individual interpupillary distance can be adjusted in a range from 54 to 76mm. With the fine helical individual focusing, precise focusing is achieved effortlessly. Extendable dew caps The integrated dew caps can be removed in high humidity and cold conditions. This avoids fogging of the outer objective lenses and effectively shields additional control light coming in from the side. Integrated carrying handle A metal carrying handle located at the center of gravity facilitates transport and ensures a secure hold during tripod assembly. Suitable tripods and tripod connectionWhen using these large binoculars, a sturdy photo tripod with an appropriate load capacity is highly recommended. The connection is made via two 1/4 inch or one 3/8 inch threaded holes (standard photo tripod thread) in the tripod adapter of the binoculars. The ideal solution is to use the optional available EXPLORE SCIENTIFIC U-Mount with field tripod (item No. 0114300). This is specially designed for the large binoculars of the BT series and carries these binoculars absolutely securely. The excellent support mechanism, with adjustable friction in both axes allows easy moving and tracking. The binocular position is kept stable depending on the adjusted friction intensity. Vibrations are reduced to a minimum by the massive construction of the U-Mount and the large stainless steel tripod. Even at high magnification there are no discernable vibrations and this allows the finest details to be observed in a chosen target.FEATURES Large binoculars for observing the starry sky, nature and landscape Observe globular star clusters, glowing gas nebulae, the moon with its craters and even planets Also wild animals, ships and airplanes can be seen in detail Highly light gathering lenses produce a bright and high-contrast image All-round binoculars, but especially suitable in twilight and at night The comfortable 45 degree viewing angle allows fatigue-free use One complete lens telescope with the full light gathering power is available per eye Extremely robust binoculars with magnesium housing, sealed and filled with nitrogen Two EXPLORE SCIENTIFIC 20mm eyepieces of the 62 degree LER series already included 33x magnification and an apparent field of view of 62 degrees, true visible field of 1,8 degreesLarge interpupillary distance of 15mm to the eyepiece lens for comfortable viewing Eyepieces interchangeable and with standardized plug-in diameter of 1.25 inch / 31.7mm The magnification can be adjusted with optional eyepieces from 25x to 75x Precise brass eyepiece compression ring clamps for tilt-free fitColor and nebula filters can be used for astronomical observations Extendable dew caps prevent fogging of the outer objective lenses and stray light Integrated carrying handle facilitates transport and mounting on the tripod Tripod connection via two 1/4 inch or one 3/8 inch threaded holes (standard photo tripod thread) Tripod recommendation: EXPLORE SCIENTIFIC U-mount with field tripod (Art.No. 0114300) Objective type: Air spaced achromatic lens (2 elements/ 1 group) Coating: full multilayer coating on all optical surfaces Aperture, focal length and aperture ratio: 120mm / 660mm / F=5.5 Sealed to IPX6 standard and nitrogen filled: yes / yes Close focus distance: 35 meters Eyepiece mount diameter: 1.25'' / 31.7mm Adjustable interpupillary distance: 54 to 76 mm Helical single focus: yes BAK-4 prism system for a bright and high-contrast imageDimensions and weight of binocular: 654 x 290 x 156mm, 8.3kg Housing colour of binocular:  white What's included Giant binocular with carrying handle (without tripod)Eyepieces ES 20mm 62 degrees LER Series (2pcs)Precisely fitting foam insert for transport Dust covers for objectives and eyepiece sockets Instruction manual

BRESSER Pirsch 9-27x56 Spotting Scope Gen. II with Tube-Focus
The BRESSER Pirsch Gen II spotting scopes are primarily intended for nature observers and hunters. Equipped with a light-intense, fully broadband multi-coated 56 mm lens, they allow higher magnifications even at twilight. This spotting scope is also equipped with the high-quality UR for brighter images. Together with the waterproof and nitrogen-filled housing and the non-reflective reinforcement, nature observers can determine e.g. bird species in any weather or hunters can target game even at long distances. Photography But also friends of digital photography will find a reliable tool in the Pirsch series: together with the DSLR adapters 49-20002 or 49-14911 almost all digital cameras or smartphones can be connected. Robust materials The focus and eyepieces are made of sturdy metal for a long-lasting pleasure with the Pirsch spotting scope. The rubber reinforcement is manufactured to ensure a firm grip.

This special coating ensures better light transmission and therefore provides a bright image even in difficult lighting conditions.

This means that transport is no problem and you can quickly work with larger magnifications than with binoculars, for example, even when you are on the move. Waterproof and nitrogen filled All Pirsch models are waterproof and nitrogen filled. So you have the perfect companion with you in all weather conditions. Rain or fog does not matter to the device. Fogging from the inside in case of large temperature differences is prevented by the nitrogen filling and thus ensures that the device is always ready for use.
