LUNT LS40THa/B1200 H-alpha Solar Telescope

Complete H-alpha solar telescope with 40mm aperture, <0.7 Angstrom bandwidth, B1200 blocking-filter, and Helical focuser.

The LS40THa/B1200 is a complete telescope for observing the sun in H-alpha, with a 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 B1200, which is excellent for visual observation of the sun. The star diagonal in which the blocking filter is installed is equipped as standard for a 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 experienced solar observers.

The LS40THa telescopes are available with 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 these telescopes have a small back focus distance, so photography is difficult. We recommend CMOS Astro Cameras with a short 12.5mm back focus distance.
