The legendary Lumicon 2" Oxygen III Narrow Band-Pass Filter isolates just the two doubly ionized oxygen lines (496 and 501nm lines) emitted by diffuse, planetary and extremely faint nebulae. Lumicon has designed a filter that enables these distant objects to be clearly seen.

The 1.25" filters employ industry-standard 1.125" x 42 tpi threads (except for Questar/Brandon, which use a thread pattern unique to Questar). The 48 mm filters employ industry-standard 48 x 0.75 mm threading, which thread into 2" eyepieces. All larger filters use the given size with 0.75 mm pitch (e.g. a 72 mm Minus Violet filter has 72 x 0.75 mm threads).

Note: Recommended for telescopes 10" or larger in aperture

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
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
