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, B500 blocking-filter, and Helical focuser.The LS40THa/B500 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 B500, this is good 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: B500 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 TelescopeB500 blocking filter in star-diagonal housing1.25 inch Helical focuserDovetail bar (GP level)Sol-SearcherInstruction manual

Ultra Light Dobsonian 406mm GENERATION II - with completely redesigned and improved construction. No telescope type has influenced amateur astronomy as radically as the dobsonian telescope. Before the introduction of this telescope type by John Dobson the vast majority of amateur telescopes were small inadequate refractors on shaky mounts - just good enough to show the polar regions on mars or the rings of Saturn. Bigger telescopes, like the Schmidt-Cassegrain telescopes, were restricted to the relatively small group of amateurs that could afford them.The brilliant combination of simple - but effective - mechanics and the largest aperture available led to a worldwide triumph of this concept. No other telescope type offers you so much light for your money as a good dobson. We have taken the motto "held together by gravity and driven by yoghurt power" and offer a modern version of the classic - designed by amateur astronomers for amateur astronomers. Despite its large aperture the telescope can be transported easily even in small cars and is assembled within minutes without tools. The construction was optimized for maximum rigidity with a minimum of mass. The combination of big altitude wheels and a optimized aluminium-sandwich construction allows for small movements even at high magnifications. The focus position is already positioned to accept our coma-corrector. The ideal workhorse for the deep-sky enthusiast. A telescope with 406mm aperture gathers more than 3300-times more light than the naked eye. Details on planetary surfaces stand out even to unexperienced observers, and countless deep-sky objects show details. Bright globular clusters are resolved down to the core and the view of the lunar terminator will provide a unforgettable experience.

Scientists at famous space agency NASA are always reaching for the stars with their missions and celestial observations. With the ISA Space Exploration NASA-themed AstroPlanetarium, you can bring a piece of this exciting world of research into your own home. But, before you get started, you should take the stickers and customise your astro projector in style with great NASA motifs. Then you can embark on your very own journey of discovery into the night sky – the 2 projection discs will bring you 8,000 stars or 61 constellations, all with names, through bright LEDs. At the optimal distance of 2 m, you can admire the image on a large total area of approx. 1.6 x 2.1 m. Flexible astro fun with the home planetarium Weather, location, time of year – all astronomers know that what you see in the night sky depends on a number of different factors. But with the AstroPlanetarium, you can devote time to your hobby whenever it suits you. Simply select the starry sky that you want to observe by setting the date and the time from 8 pm to 2 am. You’ll then see all the starry magnificence that you’d expect to see outside at that time. Gradually, you can explore every night of the year. Great additional functions for stargazers Always on the move, if you want it – with the integrated motor, you can make the image rotate at the touch of a button. Unlike the rotation of the earth, you can choose the direction of rotation and one of the 6 speed levels to suit your wishes. With shooting star mode, you can also set comet trains to pass over the night sky – who knows, maybe they’ll bring luck with them? And when it’s time to head off to the land of dreams, you can fall asleep under the stars with sleep mode, which will shut your planetarium off after 30, 60 or 120 minutes (depending on setting). Follow in the footsteps of your NASA role models and embark on your very own astro discoveries when it suits you with the ISA Space Exploration NASA-themed AstroPlanetarium.
