LUNT LS40FHa H-alpha double-stack filter for LS40THa

50mm H-alpha solar filter system with B1800 blocking filter, for front mounting at telescopes with 1.25" focuser, and up to 1620mm focal length.The LS50FHa H-alpha Etalon filter system with 50mm aperture (no central obstruction) for use on any refractor and many other telescopes. Because the LS50FHa has an estimated bandwidth of <0.75 Angstrom it is capable to providing high contrast views of both solar surface and edge detail (prominences).The system includes the B1800 blocking filter, which is usable for telescopes up to 1620mm focal length. Larger blocking filters suitable for longer focal length are also optional available. The blocking filter is installed in a 90° star diagonal for 1.25" focuser. This diagonal is equipped with a reception for 1.25" eyepieces and a T2 camera connection.Adding an additional available double-stack Etalon system will reduce the bandwidth to ~<0.55 Angstrom.FEATURESAperture: 50 mmNo central obstructionBandwidth: <0.75 AngstromTuning: tiltable EtalonHousing diameter: 95 mmLength: 73 mmWeight: 0.7 kgFront thread: M90x1 female threadRear thread: M90x1 male threadBlocking filter: B1800 in diagonal for 1.25" focuserMaximum focal length of telescope: 1620 mmSCOPE OF DELIVERYLS50FHa solar filterB1800 Blocking Filter (for 1.25" focuser) in star-diagonalTransport caseInstruction manual

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)

The anti-reflection filter is an accessory for the DSII/SFPT double-stack module for the Lunt Solar Systems LS80MT and LS100MT telescopes. Reflections that may occur there can be effectively reduced with this anti-reflection filter if necessary.At the LS80MT and LS100MT multipurpose telescopes from Lunt Solar Systems, double-stacking is possible in H-alpha mode for solar observation with the internal DSII/SFPT double-stack modules (item number 0551395). The DSII modules reduce the bandwidth to <0.5 Angstroms. The DSII modules are designed to show better the surface details of the Sun, the contrast is significantly increased, and therefore filaments and active areas are better visible.But the DSII modules can also induce reflections, which can show up as a strong brightening around the sun. This so-called ''glow'' is not a problem when observing the solar surface. But it can complicate the observation of prominences, and many observers find it disturbing. The HRG/SFPT anti-reflection filter is designed to solve this problem. The filter effectively reduces the reflections. But please also note that the image will become darker by using this anti-reflective filter.The HRG/SFPT anti-reflection filter is easy to install. It is not necessary to return the telescope to the manufacturer, the filter can be easily installed by the user.This filter cannot be used separately! It can only be used on a Lunt Solar Systems LS80MT or LS100MT telescope together with a DSII/SFPT Double-Stack module.SCOPE OF DELIVERYHRG/SFPT anti-reflection filterInstruction manual

Double-stack filter for LS50THa telescopes.The bandwidth of H-alpha systems can be reduced by so-called "double-stacking". A smaller bandwidth provides much more contrast at the solar surface, thereby many more details will become visible.Double-stacking with a bandwidth of only <0.55 Angstrom is also possible at the LS50THa telescopes. Therefore Lunt Solar Systems has especially designed this LS50C double-stack filter in compact housing. The filter threads directly onto the LS50THa telescopes.FEATURESAperture: 50  mmBandwidth: <0.55 AngstromTuning: mechanical tilt-tuningHousing diameter: 85 mmLength: 70 mmWeight: 0.7 kgFront thread: M80x1 female threadRear thread: M80x1 male threadonly usable together with a LS50THa telescope!SCOPE OF DELIVERYLS50C H-alpha double-stack filterInstruction manual
