This 40 mm H-alpha solar telescope is designed for detailed observation of the solar chromosphere in the H-alpha line (656.28 nm). Compact, lightweight and high-performance, it enables you to safely explore the protuberances, filaments, active regions and the fine texture of the solar surface.

This top-of-the-range version combines a B600 blocking filter to a Rack & Pinion eyepiece holder with 10:1 fine gearing, with maximum focusing precision, ideal for high magnifications.

Dedicated H-alpha observation

Optimized to isolate the H-alpha band, this system reveals the dynamic phenomena of the chromosphere, invisible in white light:

• Disc edge protuberances
• Magnetic filaments and structures
• Fine surface details
• Precise monitoring of the evolution of solar activity

B600 blocking filter - a more comfortable field

Visit blocking filter B600 offers a larger effective diameter than the B500, providing greater visual comfort and flexibility with different eyepieces.

• Transmission optimized for H-alpha band
• 1.25″ accessory compatibility
