Okay, that was vague -- let's try again. The Lumicon was considerably better than the TeleVue when I did the comparison. TV may have since improved the filter overall, or maybe the one I was testing happened to be defective, I don't know. I do know that Lumicon actually puts the filter bandpass rating on each one they sell, so you should have some idea up front how "good" it is. Might be worthwhile at an upcoming star party to do some comparison benchmarking of various OIII filters from different manufacturers and see if we can come up with a consensus; do some blind, objective comparisons, with only one person knowing which filter is in use taking notes... --- Richard Tenney <retenney@yahoo.com> wrote:
I compared my Lumicon with one of the early TeleVue OIII's a couple of years ago and it was considerably better. I have no idea if TV has improved their coatings (or QC) since then, FWIW.

Any opinions on which Oxygen III filters are best (for the money)? We have an Orion 1.25, but after Craig bought some larger eyepieces, he now wants a 2" for them. We were out in Rush Valley Saturday night, and either we went to the wrong place, or no one else chose to go, but just the two of us were looking at various nebula in Sagittarius between midnight and 1:00 (the Lagoon was sooo lovely) and that got us in the 2" filter wish mode. I've been told that Lumicon is better, but not necessarily enough better for the $. A Lumicon costs about $200, and Orion about $150. A salesperson at OPT claimed that the Baader filter at $98 for a 2" is better than the Orion. There are also filters by Teleview or Thousand Oaks. Any suggestions from you pros? Thanks!
