Product Description
The legendary Lumicon 2" OIII narrow band-pass filter isolates just the two doubly ionized oxygen lines (496 and 501nm lines) emitted by diffuse, planetary and 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 for telescopes 10" or larger in aperture. 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 OIII emission lines.

Lumicon Oxygen III superb on Nebulas
By Harold N. Moore
I have used Lumicon's Oxygen III filter for many years. The Veil and Helix are very dim and hard to find without the filter, but pop out with extremely bright detail when using this filter. I have used this filter with my 20-inch reflector, but it works well with any size scope. You will get fantastic views of M57 (the Ring), M27 (the Dumbell), M17 (the Swan or Omega), M8 (the Lagoon), M 44 ((the Great Orion), as well as hundreds of other nebula. I have used used other filters like the ultra high contrast, but the oxygen III reigns King!

By Fred Rayworth
I love the O-3 filter for nebulas. I have the O-3 in 1 1/4" and when I first got it, I was amazed how much it brought out diffuse nebula and planetaries. It was like having several more inches of aperture. A good example was the Veil Nebula. In my 16," it brought out extreme detail compared to the regular view through the eyepiece.When I got my set of 2" Orion Q-70 eyepieces, I needed a 2" format filter. After using several deep sky filters besides the O-3 in the 1 1/4" format, I knew that the O-3 was the only one worth the bucks in large format, except for maybe the H-Beta.This filter is amazing. I've only had a chance to use it one time this February 2008, and through the 38mm Q-70 with this filter, the Orion nebula looked almost 3-D. In fact, the swirls and festoons went way beyond the 70 degree field with the filter, whereas, without it, the nebula looked nice, but was confined to the field of view and didn't have near as much detail.I also used it on some obscure Herschel 2 planetaries and it really made them jump out against the background stars. Now keep in mind that this filter is no good for galaxies, star clusters, or dark nebula such as the Horsehead. In fact, when you are looking through it, all the stars take on a greenish purple hue and are much dimmer.Overall, this filter does the job and is a must add on to your eyepiece collection. Highly recommended.
