LS40THa/B500R&P (New standard ≤ 0.35 Å)

H-alpha 40 mm solar telescope - B500 blocking filter & rack & pinion eyepiece holder

This 40 mm H-alpha solar telescope is specially designed for observing the solar chromosphere in the H-alpha line (656.28 nm). Compact, powerful and easy to use, it lets you safely explore the Sun's dynamic phenomena: protuberances, filaments, sunspots and fine surface details.

Equipped with a B500 blocking filter and a rack & pinion eyepiece holder, It offers stable, precise focusing, ideal for fully exploiting the optical potential of visual observation.

Dedicated, secure H-alpha observation

Optimized for H-alpha solar observation, this system reveals the active structures of the chromosphere, invisible in white light.

• Spectacular protuberances at the edge of the disc
• Filaments and solar flares
• High-contrast surface details
• Monitoring the evolution of solar activity

B500 blocking filter

Visit blocking filter B500 guarantees image safety and spectral purity. Compact and lightweight, it is perfectly suited to visual use with 1.25″ format eyepieces.

• Transmission optimized for H-alpha band
• Format compatible with standard 1.25″ accessories
• Designed for safe solar observation

Rack & Pinion eyepiece holder - stability and precision

Visit rack-and-pinion eyepiece holder ensures smooth, rigid, slip-free focusing. Compared to a helical focuser, it offers greater mechanical stability, especially with slightly heavier accessories.
