Lumicon 2 Inch Econoline Oxygen III Filter

Lumicon 2 Inch Econoline Oxygen III Filter, with an average peak transmission rate of 80%, is a bargain! Current mainline Lumicon OIII filters average greater than 90%, but at half the price, the Econoline provides solid performance. The Econoline is no slouch, it compares favorably with classic Lumicon filters of years ago. It was designed to vastly outperform “bargain brand” filters at only a slight increase in price over those low performance filters.

Oxygen III narrow band-pass filters isolate 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 and produce near-photographic views of the Veil, Ring, Dumbbell and Orion nebula, among many other objects. This filter performs well under both light-polluted and dark skies.
