Guarantee & Returns
  • Isolates just the two doubly ionized oxygen lines
  • Faint objects become much more visible
  • Great for the Veil, Ring, Dumbbell and Orion
  • Performs great under light-polluted and dark skies
  • Each filter individually inspected by Lumicon

Description

The renowned, original Lumicon OIII narrow bandpass filter (11nm) isolates just the two doubly-ionized oxygen lines (496 and 501nm lines) emitted by planetary and emission nebulae while blocking the rest of the overall spectrum of light. The result is extreme contrast between the black background of space and the delicate photons of OIII light needed for near-photographic views of the Veil, Ring, Dumbbell and Orion nebulae, among other objects. See for yourselfit's truly amazing what the OIII filter allows you to see! Lumicon tests every filter individually on a Perkin-Elmer Double-Beam spectrophotometer, inscribing on the filter its % transmission for each of the primary lines.
Do not settle for cheap imitations.


Not intended for photography (use the Lumicon Deep Sky Filter).

    Excellent on Planetary Nebulae

    By Brian

    from Renton, WA

    Verified Reviewer

    Comments about Lumicon Oxygen III Telescope Filter:

    I use this product primarily for viewing planetary nebulae. Without the filter most are invisible from my light polluted skies. With the filter the sky turns black, stars turn purple, and the planetary nebulae jump out with good detail in a whitish-lavender color.

    Great Filter

    By Kyle

    from Undisclosed

    Comments about Lumicon Oxygen III Telescope Filter:

    The filter works great. Living in a city, it is very hard to view nebula. But with the filter, I am able to clearly see nebula. This is a must-have filter!

    Lumicon Oxygen III filter

    By Chuck Lappan

    from Undisclosed

    Comments about Lumicon Oxygen III Telescope Filter:

    Wow! This really puts life into nebulas in Sagittarius that I could never appreciate even with a Deep Sky Filter. Makes the Ring Nebula jump out of the sky. It is my favorite accessory.
