The BRESSER Slider Binocular Mount, with its revolutionary design, offers unprecedented comfort for binocular observation - during the day and at night Thanks to the variable extension length of the two support rails (crossbars), the cardanic mount head and various adjustable slip couplings almost all binocular positions can be selected easily. Afterwards, the binoculars remain in their respective position thanks to the counterweights. During observation, it is usually not necessary to touch the binoculars. Whether you want to observe standing up, sitting on a swivel chair or lying down on a mat or bed, everything is possible. For wheelchair users the mount is also an interesting alternative to normal tripod solutions, where usually one tripod leg is always in the way. A steady image despite large binoculars and high magnification Especially when observing for a long time, even medium-weight binoculars weighing 500 grams or more and moderate magnifications of 10x or more make life difficult. Already after a short while the pictures blur and the arms get tired. Certainly, a high photo tripod can bring a significant improvement. But this solution is very limited in terms of the binoculars’ movability and the position of the observer. The BRESSER Slider Binocular Mount offers far more possibilities. Almost all desired binocular positions can be reached effortlessly. The patented design, with 2 counter-moving support rails (crossbars), is guided on special linear roller bearings inside the mount head with zero play. This allows the observer to vary the extension length as desired with little muscle power. The sliding resistance can be infinitely adjusted using 2 adjusting screws. In the middle of the slider mount’s centre of gravity, there is an axle with adjustable slipping clutch for the tilting and rotating movement. All bearings operate with absolute precision and backlash-free. For quick levelling, there is even a 30 mm fluorescent circular bubble in the base of the mount, which is easy to read even in the dark. Cardanic mount head The cardanic mount head works like a ball head. However, it offers a significantly higher load-capacity and more stability. Here, too, the sliding resistance of all moving parts can be adjusted to the user’s specific needs. The mount head offers several mounting holes for mounting a binocular holder via 1/4-inch photo screw or a standard GP prism clamp for mounting small telescopes. In addition, there are various holes on the side cheeks of the mount head for further accessories such as red light reading lamps, smartphone holders for the use of sky apps or LED viewfinders for quick sighting of celestial objects. Counterweights Several counterweights enable the exact balancing of the binoculars or telescope. Two counterweights of each 2.5 kg, 1.25 kg and 0.5 kg are included in the package and can be attached to the rear end of the mount on the mounting bolts on both sides. With the 2 included spring clamps the weights are secured on the bolts. Instead of the counterweights, a filled sandbag can also be attached to the existing mounting hook. This reduces the transport weight for planned excursions. Suitable for use with binoculars of up to 3.5 kg weightThe BRESSER Slider Mount can be used with binoculars of up to 3.5 kg weight. But it is also a real help for obtaining blur-free images with much smaller binoculars during long-term observations. It is mounted with an optionally available binocular tripod adapter, which is attached to the mount head with a 1/4-inch photo thread screw. Also highly recommended for compact refractor telescopesInstall an optionally available standard GP prism adapter on the mount head and use your travel telescope in a completely different way: as a high-quality spotting scope for landscape and sky observation. Tripod adapter The matching tripod adapter for using the optionally available BRESSER stainless steel Tripod ST-3 (item no.: 0114310) is already included in the slider mount’s scope of delivery. It converts the standard large 3/8-inch photo tripod thread (internal thread) in the base of the slider mount into a metric M10 thread. This means that after removing the adapter, a stable standard photo or video tripod with 3/8-inch mounting screw can also be used.GETTING STARTED VIDEO:  https://www.youtube.com/watch?v=AhJm3Cl1e9IFEATURESBRESSER Slider Binocular Mount without Tripod Enables comfortable and fatigue-free binocular observation Suitable for landscape and sky observation Shake-free and steady images at day and night Almost infinitely rotatable and swivelling cardanic mount head Supports binoculars and telescopes up to 3.5 kg weight Various observer positions are possible: standing, sitting and lying down Also a practical alternative to a photo tripod for wheelchair users Adjustable viewing height from approx. 30 cm to 170 cm (when using the BRESSER tripod, item no. 0114310)Dimensions when fully assembled: 125 x 35 x 180 cm (when using the BRESSER tripod, item no. 0114310)Total weight mount head incl. accessories: 14.5 kgWeight of mount head: 6 kg  Large 30 mm fluorescent circular bubble in the mounting base Mounting holes for further optional accessories available Several balance weights include: 2x 2.5 kg, 2x 1.25 kg, 2x 0.5 kg Adjustable friction clutches on all movable axes All surfaces high quality painted, powder coated or anodised Precise small series production - manufactured in the EU (Hungary)SCOPE OF DELIVERYSlider mount (binoculars + tripod not included)Tripod adapter 3/8 inch to M10 thread Balance weight 2.5 kg (2 pieces) Balance weight 1.25 kg (2 pieces) Balance weight 0.5 kg (2 pieces) Locking device for counterweights (2 pieces)

Solar observation in H-Alpha: prominences, filaments, flares ... the most spectacular way to see the Sun - easy and affordable with the LS40THa.Complete H-alpha solar telescope with 40mm aperture, <0.7 Angstrom bandwidth, B1200 blocking-filter, and Helical focuser.The LS40THa/B1200 is a complete telescope for observing the sun in H-alpha, with 40mm aperture (no central obstruction) and 400mm focal length. The H-alpha wavelength is the most impressive way to observe the sun, showing protuberances at the sun's edge, filaments and flares on the surface, and much more. An Etalon with mechanical tilt-tuning provides <0.7 Angstrom bandwidth.Fine adjustment is achieved with a 1.25 inch Helical focuser. Blocking-filter is the B1200, this is excellent for visual observation of the sun. The star diagonal in which the blocking filter is installed, is equipped as standard for 1.25 inch eyepiece connection.The easy handling makes this telescope ideal for starting H-Alpha solar observation. Due to its compact dimensions it is also a good travel telescope for the experienced solar observers.The LS40THa telescopes are available with choice of B500, B600 or B1200 blocking filters. The larger blocking filters provide less edge obstruction and a larger field of view for visual observation and photography. Please note that these telescopes have only a very small back focus and therefore photography is difficult. We recommend special astro cameras for photography, which have a very short distance to the sensor, such as the BRESSER Full HD camera item number 4959050.FEATURESAperture: 40mm (no central obstruction, 2-lens refractor)Focal length: 400mmBandwidth: <0.7 AngstromTuning: mechanical tilt-tuningBlocking filter: B1200 with 1.25 inch connectionFocuser: Helical focuserDovetail bar at standard GP-level1/4-20 tapped base (standard thread for photo-tripods)Sol-Searcher includedWeight: 1.2kgLength: 41cmSCOPE OF DELIVERYLS40THa Solar TelescopeB1200 blocking filter in star-diagonal housing1.25 inch Helical focuserDovetail bar (GP level)Sol-SearcherInstruction manual
