Lunt LS40THa/B500 H-alpha solar telescope

The LS40THa/B500 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 B500. 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.
