Modular designed multipurpose telescope, both for observing the sun in the H-alpha wavelength, as well as for night sky observations. Easy conversion between the different applications with a few simple steps. Excellent image quality due to 2-lens ED optics with 70mm aperture for night sky observation, and 60mm usable aperture for H-alpha solar observation.With innovative air pressure tuning system, high-quality 2 inch (50.8mm) Rack&Pinion (R&P) focuser, and B1200 blocking filter.Solar observing in H-alpha:The LS60MT/B1200 is a complete telescope for observing the sun in H-alpha light, with 60mm free aperture (no central obstruction) and 420mm 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 internal Etalon filter achieves a bandwidth of <0.7 Angstrom with the innovative air pressure tuning system Pressure-Tuner. Tuning is done by slightly changing the air pressure in a pressure chamber inside the telescope. This changes the refractive index of the air, making it easy to tune to the H-alpha line. The pressure tuner guarantees a homogeneous image, without central obstruction, and a permanently protected Etalon without erosion. A set of collimating lenses installed in the telescope ensures best performance.Fine adjustment is achieved with a solid 2 inch Rack&Pinion focuser with 10:1 reduction.Blocking-filter is the B1200. The B1200 is very good for visual solar observing, and also for solar imaging.The star diagonal in which the blocking filter is installed, is equipped as standard for 1.25 inch eyepieces and with a T2 camera connection.Observing the starry night sky:The H-alpha Etalon system can be removed from the telescope in a few easy steps thanks to its modular design. The 2-lens ED refractor can then be used as a normal telescope with 70mm aperture and 420mm focal length for observation and photography of the night sky. The ED Doublet lens will offer an excellent image. It can be used with a standard 2 inch zenith mirror at the R&P focuser.With an additional Amici prism, the telescope can of course also be used during the day for nature and landscape observations.This makes the LS60MT, with its small dimensions and low weight, also an ideal travel telescope for all applications!More applications:With additionally available accessories the LS60MT offers even more possibilities!- Double-StackThe LS60MT telescope can optionally be upgraded with the additionally available double-stack filters LS50FHa or LS60FHa (part numbers 0550200 and 0550250). These filters will be simply screwed on the front of the LS60MT, no additional adapters are necessary. Thereby a bandwidth of <0.5 Angstrom is achieved for H-alpha solar observation. Therefore much more details on the solar surface will become visible.- Solar observing in White-LightIf the H-alpha unit has been removed, of course either a sun filter to be installed in front of the objective, or a Herschel-wedge at the focuser can be used to observe the sunspots in White-Light.- Solar observing in Ca-K wavelengthCertainly, the Ca-K filter modules from Lunt Solar Systems can also be used at the LS60MT to observe and photograph super-granulation and other effects visible in this wavelength on the sun.This makes the LS60MT a completely universal usable telescope!FEATURES2-lens ED refractor, FPL-51Aperture: 70mmUsable aperture in H-alpha: 60mm (no central obstruction)Focal length: 420mmBandwidth: internal Etalon with <0.7 AngstromTuning: air pressure tuning system Pressure-TunerBlocking filter: B1200 with 1.25 inch and T2 connectionFocuser: Rack&Pinion focuser with 10:1 reductionTube-ring with 1/4-20 tapped base (standard thread for photo-tripods)Weight with H-alpha unit: 3.8kgWeight without H-alpha unit: 2.6kgLength with H-alpha unit and blocking filter: 40cmLength without H-alpha unit: 31cmSCOPE OF DELIVERYLS60MT Multipurpose TelescopePressure-TunerB1200 blocking filter in star-diagonal housing2 inch Rack&Pinion focuserTube ring with 1/4-20 connection for mounting on photo-tripodsTransport case (53x33x17cm)Instruction manual

The new NATIONAL GEOGRAPHIC WIFI Colour Weather Station with 7-in-1 professional outdoor sensor offers a comprehensive information service. The multifunctional outdoor sensor can easily be installed using the installation accessories supplied! The sensor reliably transmits measured values for wind speed, wind direction, humidity, temperature, amount of precipitation, as well as UV level and light intensity to the base station via 868 MHz frequency. The console's clearly structured 5.7" colour display shows a large variety of measured local data as well as your station's historically measured values. A reliable local weather forecast is calculated and displayed using weather symbols on the console display for the upcoming 12h. The WIFI function allows users to share their local data via online platforms such as "AWEKAS", ''Weather Underground'' or ''Weather Cloud''. Furthermore, the WIFI function enables Internet time synchronization and firmware updates.  You can set a temperature alarm for maximum and minimum values, which triggers both an acoustic and a light signal when the specified value is reached. For outside temperatures from -3°C, a special alarm can also be activated to warn of frost/ice. A poor indoor climate often poses health risks, especially for children and older people. The BRESSER WIFI colour Weather Station offers a smart feature for this as well. The indoor climate indicator always informs about the indoor climate by means of a symbol. For all ''moon addicts'' the different phases of the moon are also displayed. An alarm clock with snooze function is also included in the range of functions.  You can transmit your weather data to the European Weather platform AWEKAS where you can also retrieve your weatherdata worldwide. Transmit data such as air temperature, humidity, soil temperature and humidity, pool water temperature to your smart home control system, depending on which sensors you have additionally purchased. This can be done easily and free of charge via our partner AWEKAS.

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
