Also known as the Horsehead Nebula filter, Farpoint's H-beta Filter isolates only the hydrogen-beta line of the spectrum (486nm) in a narrow pass-band just 9 nm wide, providing maximum contrast. Now you can view extremely faint nebulous objects such as the Horsehead, Cocoon and California Nebulae. In many cases, the Hydrogen-Beta Filter is the ONLY way to view these objects. Recommended for 8" or larger telescopes. To ensure that your Farpoint filter remains the World's Best, the strictest quality control standards are employed throughout the production process. Each Farpoint Hydrogen - Beta Filter is individually inspected and produce a matched report of transmission and blocking band performance.
