H-alpha solar observation: prominences, filaments, flares... The most spectacular way to view 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 a 40mm aperture (no central obstruction) and a 400mm focal length. The H-alpha wavelength is the most impressive way to observe the sun, revealing prominences at the edge of the sun, filaments and flares on the surface, and much more. A mechanically tilt-adjustable etalon provides a bandwidth of <0.7 angstrom. Fine adjustment is achieved with a 1.25-inch helical focuser. The blocking filter is the B500, which is good for visual observation of the Sun. The star diagonal on which the blocking filter is installed is equipped as standard for connecting 1.25-inch eyepieces. Its ease of use makes this telescope ideal for beginners in H-alpha solar observation. Due to its compact dimensions, it is also a good travel telescope for experienced solar observers. The LS40THA telescopes are available with the option of B500, B600, or B1200 blocking filters. The larger blocking filters provide less edge obstruction and a wider field of view for visual observation and photography. Note that these telescopes have very little back focus, making photography difficult. We recommend special astronomical cameras for photography, which have a very short distance to the sensor, such as the Bresser Full HD camera number 4959050.
