Lunt LS50THa 50 mm H-Alpha Solar Telescope - Standard Kit

Lunt LS50THa - complete H-Alpha Solar Telescope for Observation and Photography

The LS50THa allows for solar observation and photography in the H-alpha band. It is a true "grab-and-go" telescope that reveals the details of the chromosphere, prominences, and filaments that make H-alpha observation so rewarding. The complete, ready-to-use telescope is stored in a case. All you need is a camera tripod or a small tracking mount.

The 1.25" helical focuser
The helical focuser allows for precise focusing, whether for photography or observation. When adjusting the focus, the 1.25" blocking filter does not rotate.

12 mm 1.25" flat-field eyepiece
The 12 mm eyepiece (29x magnification) is your all-purpose solar eyepiece. It provides sufficient magnification for surface details and a sufficiently wide field of view to keep the entire Sun in view.

What can you see on the Sun with the LS50THa
You can explore everything the LS50THa reveals at a bandpass of <0.65 Å. Resolve active regions on the solar disk into complex structures of light and dark, and observe the details of prominences - from soft arcs to clearly defined loops and filaments. Survey the entire limb for prominences, trace filaments across the hemisphere, and watch the slow evolution of active regions over the course of an observation session.

Pressure tuning
Pressure tuning remains your most powerful tool. Scan through the chromosphere at any magnification. Watch structures appear and recede as you shift through the hydrogen-alpha line.

Photographing the Sun with the LS50THa
Of course, you can also photograph the sun. The blocking filter also features a T2 thread on the eyepiece side for attaching cameras. The solar disk has a diameter of less than 3.5 mm at the focal point. The blocking filter with 4 mm of clear aperture therefore still provides enough space. However, we recommend using a tracking system to keep the sun exactly in the center. For solar photography, we recommend cameras with a 1.25" connection. We´ve linked a few suitable cameras in the accessories section.
