50 mm H-alpha solar telescope - B400 blocking filter & Rack & Pinion eyepiece holder

This 50 mm H-alpha solar telescope is dedicated to detailed observation of the solar chromosphere in the H-alpha line (656.28 nm). Thanks to its larger aperture than 40 mm models, it offers a significant gain in resolution and in brightness, The result is an even finer picture of the Sun's dynamic phenomena.

This version is equipped with a B400 blocking filter and a rack & pinion eyepiece holder, for stable, precise focusing.

H-alpha solar observation

Optimized to isolate the H-alpha band, this system makes it possible to observe :

• Spectacular protuberances at the edge of the disc
• Dark filaments and magnetic structures
• High-contrast fine surface details
• Daily evolution of solar activity

The 50mm aperture provides better detail separation and higher contrast.
