Lumicon 1.25 Inch Hydrogen-Beta Filter


Lumicon 1.25 Inch Hydrogen-β Filter is also known as the Horsehead Nebula filter. This filter isolates only the hydrogen-β line of the spectrum (486nm) in a narrow pass-band just 9nm wide, providing maximum contrast.

Aids in viewing of extremely faint nebulous objects such as the Horsehead, Cocoon and California Nebulae. In many cases, the Lumicon Hydrogen-Beta Filter is the ONLY way to view these objects. Recommended for 8″ or larger telescopes.

Lumicon filters remain the world’s best and strictest quality control standards are employed throughout the production process. Each Lumicon Hydrogen-β Filter is individually inspected and proudly inscribed with the percentage of light transmittance of the H-Beta emission line.
