Lunt LS40THa B600 H-alpha solar telescope

Product Description

.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.

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 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.
