Lumicon H-beta Filter - 1.25"

This 1.25-Inch Hydrogen-Beta Filter from Lumicon aids in viewing of extremely faint nebulous objects such as the Horsehead, Cocoon, and California Nebulae.

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

In many cases, the Lumicon Hydrogen-beta Filter is the ONLY way to view these faint objects.

Recommended for 8-Inch or larger telescopes.

Lumicon filters' quality control remains the world’s best and strictest quality control standards and they are employed throughout the production process.
