H-alpha LUNT LS40THa/B500 H-alpha solar telescope

Full H-alpha solar telescope with 40 mm aperture, 40 mm bandwidth, 40 mm bandwidth, 40 mm bandwidth

The LS40THa/B500 is a complete H-alpha solar observing telescope with 40 mm aperture (no central obstruction) and 400 mm focal length. The H-alpha wavelength is the most impressive way to observe the sun, showing bumps on the edge of the sun, filaments and flares on the surface and much more. An Etalon with mechanical tilt adjustment provides a bandwidth of
Fine adjustment is achieved with a 1.25-inch helical focuser. The blocking filter is the B500, this is good for visual observation of the sun. The diagonal star on which the locking filter is installed is equipped as standard for the connection of 1.25-inch eyepieces.

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.

LS40THa telescopes are available with a choice of B500, B600 or B1200 blocking filters. The larger blocking filters provide less edge obstruction and a larger field of view for visual observing and photography. Note that these telescopes have a very small back focus and therefore photography is difficult. We recommend special astro cameras for photography, which have a very short backfocus distance.
