Product information "LUNT LS40THa/B600 H-alpha solar telescope"
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, B600 blocking-filter, and Helical focuser.


The LS40THa/B600 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 B600, this is very 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.

BRESSER Twilight I telescope mount with tripod
The Twilight I is a light-to-medium-duty alt-azimuth mount with tripod designed to quickly and easily accept small to medium sized refractors, such as the AR102 + AR127s or ED102mm + ED127, and of course, the ED80mm. Lightweight, fast Newtonians will also match up nicely with the BRESSER Twilight I mount. As long as your telescope does not exceed 18 pounds and has a Vixen-Style Universal Dovetail bar for mounting the telescope to the mount head, you are good to go. The Twilight I alt-azimuth mount head is made of powder-coated aluminum and there are worm gears on both axes. The adjustable angle head can be tilted forward or back at a 45° angle to allow more clearance for your telescope so you can point it straight up for viewing at the zenith. The Allen hex wrench for doing the mount head adjustment can be safely stored at the integrated magnetic holder.  Slow-motion control cables are attached on the vertical and horizontal axes, and are easy to turn during the night, even with gloves on, due to the over-sized knurled knobs that are attached to the end of each cable. They can be attached to either side of each axis to accommodate right or left-handed users, or different types of telescopes (e.g. refractors vs. Newtonian reflectors) for ease of adjustment. The stainless steel tripod that comes standard with the Twilight I mount has adjustable legs and a wide foot print of 42 inches, which makes the tripod more stable. A spreader bar locks against the inside of the legs to secure the tripod even further, and keep vibrations to a minimum. SCOPE OF DELIVERYTwilight I Telescope MountStainless Steel Field tripod

BRESSER Space Explorer MC 90/1250 Automatic-Telescope
Who hasn't dreamed of a trip to the stars? The BRESSER Space Explorer MC 90/1250 automatic telescope will take you on an exciting journey into space. The telescope is easy to use, even for beginners - after aligning with one, two or three stars, you can choose an object from the 270,000 pre-installed celestial objects. Whether you want to observe a fascinating gas planet or a bright deep-sky object, the telescope will automatically move to your desired target. Thanks to the built-in motors in both axes of the azimuthal mount, the target object is automatically tracked so that you can sit back and enjoy the night sky. Explore the night sky with the Maksutov telescope Featuring a long focal length of 1250 mm, this telescope is ideal for making exciting discoveries in the solar system and beyond. Take a close look at the gas clouds on Jupiter, or watch the rings of Saturn through the telescope for the first time with your own eyes. Thanks to the 90 mm aperture, the telescope collects about 165 times more light than the human eye. However, it's not just the planets that look stunning through the high-quality optics. It's also worth venturing further afield into space: marvel at the sight of the Orion Nebula, 1,344 light years from Earth, or the famous Ring Nebula M57 in the constellation Lyra. The two included eyepieces with 25 mm and 12.5 mm focal lengths will show you these objects and many others at 50 or 100 times magnification. And because the best observation spots are usually not found in your immediate vicinity, the telescope features a compact Cassegrain design for easy transport. If there is a stable table at your observation site, you can even leave the tripod at home. Everything you need for exploring the night sky The telescope also allows you to capture images of the night sky. Simply attach the smartphone holder to the eyepiece, and take snapshots of planets, open star clusters and other night sky objects. The telescope is also ideal for observing and taking photos of the moon. In order to comfortably watch Earth's natural satellite through your Maksutov-Cassegrain telescope, it is best to use the included moon filter. The moon filter darkens the image slightly and increases the contrast to provide a more comfortable view. Perfect for exploring fascinating moon craters, lunar seas and shadows in the twilight zone! The telescope also comes with a star chart to help you navigate the night sky with its mythically named constellations.
