Product information "LUNT LS50FHa/B3400 H-alpha solar filter"
50mm H-alpha solar filter system with B3400 blocking filter, for front mounting at telescopes with 2" focuser, and up to 3060mm 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 B3400 blocking filter, which is usable for telescopes up to 3060mm focal length. The blocking filter is installed in a straight extension tube for 2" focuser. This extension tube is equipped with a reception for 2" eyepieces and a adapter for 1.25" eyepieces.

Adding an additional available double-stack Etalon system will reduce the bandwidth to ~<0.55 Angstrom.

FEATURES
  • Aperture: 50 mm
  • No central obstruction
  • Bandwidth: <0.75 Angstrom
  • Tuning: tiltable Etalon
  • Housing diameter: 95 mm
  • Length: 73 mm
  • Weight: 0.7 kg
  • Front thread: M90x1 female thread
  • Rear thread: M90x1 male thread
  • Blocking filter: B3400 in extension tube for 2" focuser
  • Maximum focal length of telescope: 3060 mm

BRESSER NightExplorer 15x70 Astronomy Binoculars
Whether you want to explore the night sky or make terrestrial observations during the day, the BRESSER NightExplorer 15x70 astronomy binoculars will ensure that you are perfectly equipped for all your outdoor adventures. The extra large lens diameter of 70 mm lets a large amount of light into the binoculars, while the 15x magnification ensures that you obtain highly detailed images of your observed targets. Fully multicoated optics ensure scattered light is kept to a minimum, so that you can enjoy a perfect view with the best possible optical performance. At a distance of 1000 metres, the field of view is 77 metres wide. The highly corrected eyepieces with 5 lenses in 3 groups produce vivid images with sharp edges. Coating The premium BaK-4 optics (barium crown glass) features a full multi-coating to increase light transmission and reduce reflections. Focusing Thanks to the individual eyepiece adjustment, you only need to focus the binoculars once. You can then enjoy a sharp image at infinity for the night sky. The binoculars also have a close focus, which you can set from a distance of 10 metres or more for close-up observations of your immediate surroundings. Also suitable for glasses wearers Thanks to the foldable eyecups, you can set the optimal distance between your eyes and the ocular lenses. If you wear glasses, this allows you to see the entire field of view of the Porro-prism binoculars. There is also a dioptre compensation of +/-8, which you can use to compensate for small differences in vision between your eyes. Weatherproof and robust Thanks to their waterproof design, the binoculars can be used in wet or foggy weather conditions, as water and moisture cannot enter the housing. The binoculars are filled with argon to stop the optics from fogging up. In addition, the ergonomic armouring provides a secure grip and protects the binoculars against impacts and knocks, making them ideal to travel with. Portable design The 15x70 Porro-prism binoculars come with an excellent lightweight aluminium tripod, with study ballhead mounting, to ensure wobble-free astronomical or terrestrial observations. Both the binoculars and the tripod can be stored in the sturdy padded backpack, which is also included in the set. This ensures that you can easily transport your gear to your desired vantage point, even if you have to go a long way to get there. Discover the night sky and the wonders of nature with the powerful BRESSER NightExplorer 15x70 astronomy binoculars!

BRESSER Messier NT-203/1000 Hexafoc Optical Tube
NEW – now including a high-quality aperture Solar-filter for safe observation of sunspots, eclipses and planet transits. Great telescope for night and solar observation.The BRESSER Messier NT-203 telescope with a parabolic main mirror provides you images that a few years ago were impossible in this price class. Modern production technology lets you track the shadows of Jupiter's moons on the planet; the amount of structure and details on the surface of the planet is breathtaking. But the BRESSER Messier NT-203 is not only great for planetary observation: Detect details in faint distant galaxies and let the glow of nebulae take you to a journey into the depth of the milky way. The BRESSER Messier NT-203 provides you with images from the remains of giant exploded stars and gives you a view into the nursery of new stars. Let this big scope take you away to the beauty of the universe! Please note: Reflector telescopes with optical design Newton are very good for astronomical observing at the starry night sky. But these telescopes are not well usable for observing landscape and nature during daylight. Therefore we suggest BRESSER refractor (lens) telescopes for landscape and nature observing.CHARACTERISTICSOptical design: reflector telescopeMirror diameter: 203 mm / focal length: 1000 mm / F/5Maximum recommended magnification: 406x Telescope for night and solar observingVery high quality Hexafoc focuser with 2,5" free inner diameterDiffraction limited optics with parabolic main mirror8x50 straight through viewfinder with reticleOptimized finder socket for comfortable use Cradle rings with handle and integrated piggyback camera holder (1/4 thread)Smartphone adapter for celestial navigation includedDovetail plate with stainless steel rail 50,8 mm (2) to 31,7 mm (1,25) adapter with integrated T2 thread (T2-adapter ring for your camera is needed) SCOPE OF DELIVERYOptical tube 26 mm Super Plössl eyepiece 31,7 mm (1.25") Integrated 31,7 mm and T2 adapter Prism rail with stainless steel clamping surface Adapter for 50.8 mm (2") eyepieces 8x50 optical viewfinder Rotatable star map Aperture solar filter Tube clamp with handle and camera holder Smartphone adapter for celestial navigation Software Stellarium (via download)

EXPLORE SCIENTIFIC 2" O-III Nebula Filter 6.5nm
One of the most important obstacles for the exploration of the night sky is the brightening of the night sky by artificial lighting, such as street lights. The night sky is not really dark in the vicinity of towns or cities, which reduces the visibility of objects beyond the solar system enormously. Depending on the type of celestial object, it is possible to increase the contrast dramatically by blocking the interfering artificial light. The EXPLORE SCIENTIFIC O-III filteruses a characteristic property of the so-called emission nebulae. Those objects glow in special colours, the so-called emission lines. Those emission lines are linked to chemical elements - in this case, oxygen. The EXPLORE SCIENTIFIC O-III nebula filterblocks all other colours (and thereby nearly all the artificial light) and only the two emission lines of the oxygen can pass the filter. The result is astonishing: suddenly, nebulae are visible in locations that were completely empty without using filters. In suburban skies, for example, the veil nebula NGC 6992 is almost invisible with a 200 mm telescope. By using this filter, you can see the nebula and its structures without any difficulties. A must for every visual observer and for astrophotography. The EXPLORE SCIENTIFIC nebula filterscome with an individual test certificate - your guarantee for receiving a premium filter. This filter's narrow passband of only 6.5 nm bandwidth highlights the faint emission nebulae or makes them visible even under difficult urban conditions. FEATURES enables the observation of so-called emmission nebulae blocks almost the entire artificial light only the two emmission lines of the oxygen passes the filter band pass width: 6.5 nm narrow band version for difficult urban conditions allows more contrast for faint deep sky objects ideal for use near cities, in heavy brightened skies individual test certificate included to guarantee you receive a premium filter SCOPE OF DELIVERY 1x 2'' O-III nebula filter
