Lumicon 1.25" Oxygen III (OIII) Filter - Gen 3

The improved Gen 3 Lumicon 1.25" OIII narrow band-pass filter isolates just the two doubly ionized oxygen lines (496 and 501nm lines) emitted by diffuse, planetary and extremely faint nebulae. Thus, these faint objects become much more visible against the blackened background of space. The Lumicon Oxygen III Filter produces near-photographic views of the Veil, Ring, Dumbbell, and Orion nebula, among many other objects. Performs well under both light-polluted and dark skies. Recommended with eyepieces that yield a 5 mm to 7 mm exit pupil. To ensure that your Lumicon filter remains the World's Best, the strictest quality control standards are employed throughout the production process. Each Lumicon Oxygen III Filter is individually inspected and proudly inscribed with the percentage of light transmittance of the two OIII emission lines.
