Product Info

Manufacturer Description

The legendary Lumicon 2in 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.

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.

      5.0 Great accessory for 6" & larger telescope

      Pros:

      Quality Lenses,Easy to Use

      Cons:

      Somewhat expensive

      Comments:

      I originally bought this filter for use with a 12" F/5 Dobsonian, but I found that it works great with a 6" F/8 Newtonian too.

      I live on the edge of a Red/Orange light pollution zone, and I could never see the Helix Nebula with my 6" Newt until I got this filter. I can also see the Veil Nebula with my 6" Newt and it brings out extra detail with other objects like the M8 Lagoon Nebula & M17 Swan Nebula.

      I consider this accessory a must if you want to get the most out of a larger telescope too. I liked the 1-1/4" version so much that I also bought a 2" Lumicon OIII filter for my wide field eyepiece that I use with my 12" Dob. The filter makes objects visible in the 12" Dob that are not visible without it (ex. The Veil Nebula is not visible in 12' Dob w/o OIII filter).

      I use to have a broadband light pollution filter, but I found that the Lumicon OIII out performs it in every aspect.

      I will caution you that OIII Filters will not improve your view of galaxies, globular clusters, or open star clusters.

      5.0 A great filter for the deep sky

      Pros:

      Quality Lenses,Compact,Easy to Use

      Cons:

      Comments:

      The Lumicon oxygen III filter is the best filter to observe the deep sky.
      Through an OIII filter, M8, M17, M42 and the veil nebula are impressive and highly visible.
      This filter is recommended for a telescope of 8 inches or more.

      Quality Lenses,Accurate,Easy to Use

      Cons:

      None for me

      4.0 Simply the best!

      Pros:

      Compact,Easy to Use,Lightweight,Strong Construction,Quality Lenses,Accurate

      Cons:

      Comments:

      Lumicon are simply the best in terms of interferential filters for astronomy. Quality of lens and technical design (narrowband) have no competition.

      5.0 Lumicon Oxygen III (OIII) Filter 1.25"

      Pros:

      Much improved contrast,Very high quality coating

      Cons:

      No cons on this product

      Comments:

      This is the best filter for both visual and ccd imaging!! Even in a dark area, this filter shows some objects with a 20-30% improvement!! A must own filter with your/my Lumicon set!!

      Lumicon says::
      OIII best on 33 nebulae (biased by the inclusion of some planetary nebulae), close second best on 23 nebulae. *NOT* recommended on 6 nebulae.
      TOTAL 1st and 2nd recommendation for OIII: 56 objects.

      [Comment submitted by user gabramovich] "This type of narrowband filter doesn't enhance objects like galaxies."
