Description:The Original Lumicon Ultra-High Contrast narrow bandpass filter (24nm) isolates just the two doubly-ionized oxygen lines (496 and 501nm lines) and H-Beta line (486nm) emitted by emission and planetary nebulae, while blocking the rest of the overall spectrum of light. The result is extreme contrast between the black background and the delicate photons of nebula light needed for near-photographic views of the Orion, Lagoon, Swan and planetary nebulae, among others. This makes the Lumicon UHC Filter the best all-around nebular filter on the market today. See for yourself -- it's truly amazing what the Lumicon UHC 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, foreign made, low-transmission ultra-block type filters. Not intended for photographic use.

Lumicon UHC
I couldn't believe what a difference this filter made. Even from a dark-sky site, and with a 16" Dobsonian, the difference when viewing the Veil was astonishing. It was easily visible without the filter, but with it, the Veil looked just like photographic images, with fine detail easily visible.

I bought mine second-hand but would certainly buy one new if I had to. Not exactly cheap but if DSOs are your target then I think one of these is a great investment.

If you are looking for a nebula filter the Lumicon UHC is the one I would recommend, I have used it on a 102mm refractor, 8"dob and also my 15" dob and it was very useful in each one. I would recommend this over the O-lll because the contrast tends to be so extreme with the Olll.

I myself find the image noticeably dimmer, but the planetary nebula themselves appear a bit brighter. I cannot make out any better detail, but the nebula does have a slightly better contrast. I prefer to keep the brighter image myself, so this rarely is used. When hunt for really faint PN, I do pull it out and move it over the eyepiece lens without mounting it, just to see if it will "pop" out better.

I have also used this on planets, and helps a bit too.

My all-time favorite filter for my 18" Obsession Dob. Gives a big boost to DSOs without the contrast blowout of the Lumicon O-III.

This may be the best narrowband nebula filter available today. It really pops the contrast for emission and planetary nebulae. Compared to the Astronomik UHC, much better contrast, making the effect of the Astronomik seem downright anemic.

I bought it used so it was cheeper, otherwise it (to me) is a lot. But it really helps on the Orion Nebula and some by the Sag. teapot
