Orion 5583 1.25-Inch Hydrogen-Beta Eyepiece Filter
Product description Our Hydrogen-Beta Filter may be the only way to see the
faint and elusive Horsehead, California, and Cocoon Nebulas. It blocks
everything but the hydrogen-beta light these faint nebulas emit, providing the
contrast needed for viewing. By isolating the hydrogen-beta spectral line
centered at 486.1 nm in a 12nm band-pass and blocking other wavelengths, it
effectively blackens the background sky, allowing the faint nebula to become
clearly defined. It increases contrast even under dark skies so you can
visually capture these prized targets. Use with a moderate to large aperture
telescope under clear, dark viewing conditions. Threaded to fit 1.25" and 2"
eyepieces and diagonals. From the Manufacturer Orion's Hydrogen-Beat eyepiece
filter makes it possible to view the elusive Horsehead, California, and Cocoon
Nebulas in dark skies. Selective band-pass filter transmits only the hydrogen-
beta light these faint nebulas emit. Filter allows you to observe targets that
are considered trophies of visual astronomy. Best used with a moderate to
large aperture telescope and clear, dark skies. Threaded to fit 1.25"
eyepieces and threaded diagonal barrels
