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, B500 blocking filter and helical focus.

The LS40THa/B500 is a complete telescope for observing the sun in H-alpha, with 40mm aperture (without central obstruction) and 400mm focal length. The H-alpha wavelength is the most impressive way to observe the sun, showing bulges at the edge of the sun, filaments and flares on the surface, and much more. An Etalon with mechanical tilt adjustment provides < 0.7 Angstrom bandwidth.

Precise adjustment is achieved with its 1.25-inch helical focus. The blocking filter is the B500, suitable for visual observation of the sun. The star diagonal on which the blocking filter is installed is equipped as standard for the connection of 1.25 inch eyepieces.

Its easy handling makes this telescope ideal for getting started in H-Alpha solar observation. Due to its compact dimensions it is a good travel telescope for experienced solar observers.

LS40THa telescopes are available with your choice of B500, B600 or B1200 blocking filters. Larger blocking filters provide less edge obstruction and a larger field of view for visual observation and photography. Please note that these telescopes only have a very small back focus and therefore photography is a difficult task. We recommend special astro cameras for photography, which have a very short distance to the sensor, such as the BRESSER Full HD camera number 4959050.
