Precision Viewing with Standard Eyepieces
The LS40THa/B500 solar telescope features a 40mm aperture (unobstructed) and a 400mm focal length, optimized for breathtaking views of the Sun's edge and surface details in H-alpha light. Its Etalon system, with mechanical tilt-tuning, ensures sharpness and clarity with less than 0.7 Angstrom bandwidth. Adjustments are a breeze with the 1.25-inch Helical focuser, and the B500 blocking filter, housed in a star diagonal, supports standard 1.25-inch eyepieces for a wide range of viewing experiences.

Travel-Friendly Design
Designed with portability in mind, this compact telescope is perfect for both beginners and seasoned solar observers on the move, offering a straightforward setup for exploring the Sun's dramatic features in H-Alpha light.

Customizable Viewing Experience
Choose from B500, B600, or B1200 blocking filters to tailor your viewing experience. Larger filters provide an expanded field of view and reduced edge obstruction, ideal for both visual observation and photography. Note: Due to limited back focus, we recommend using specialized astro cameras for photography to achieve the best results.
