The new Generation 3 Lumicon OIII filters are here! Scan and pictures will be posted soon, but suffice to say that they are awesome! Available for purchase now, will ship Thursday or Friday. As always, $200 for the 2" LF3045 and $100 for the 1.25" LF3040.

 

We have a limited quantity of the Classic OIII filters and we are selling them off at half price! Available now on our website, they have a "C" suffix on the part number, so LF3045-C and LF 3040-C.  Both Lumicon Gen 3 and Lumicon Classic OIII filters are available now on the FarpointAstro.com website.

I forgot to add that you will be able to tell the difference because the new Generation 3 filters will say Gen3 on the filter cell.  :-)

Any "A/B" astro images showing the difference/improvement between these and previous iterations?

Clear Skies,

Gen 3?

I can count at least 8 different O-III filters from the Livermore days forward.

OSI is the 4th owner, and there has been a different version from each owner, so this is at least the 4th generation.

Well, whatever they want to call it.

Don,

 

You are, of course, very correct. :-)

 

It would more accurately be Gen9, but that doesn't sound like good marketing. Further, it would just result in confusion because historical documentation of the past models is sadly lacking. The part numbers never changed over the years. Everybody would want to know what generation their 1981 filter was. I have no idea. So there you have it. Maybe we should have gone with "Special Edition" or "Diamond Series" or something like that. Sounds a little too Madison Avenue to me, though.

 

Our Gen3 moniker was chosen to differentiate the new model, acknowledge past variants, and (at the same time) limit confusion. The Gen3 will say "Gen3" on the filter cell, but it will retain the old part numbers (LF3040 for the 1.25" and LF3045 for the 2").

 

Obviously there were many models before we acquired Lumicon. We lump them together as Gen1a-g but they never had a historical differentiating model number, so call them what you wish. There is the model that OSI put out after we acquired Lumicon, we are calling that the "Classic". The Classic is exactly the same as the last model that Lumicon put out before OSI acquired Lumicon. Yes,"Gen2" would been more logical but we had already picked the Classic name before we created the Gen3 name. We are selling off the "Classic Edition" (our previous model) at a huge 50% discount just to clear things out and start fresh. So going forward, there will only be the Gen3. Again, it will say Gen3 on the filter cell but the part numbers will be the same as they always have been.

 

Is the Gen3 an improvement over Classic Edition? Yes it is. It the Gen3 THAT much better (50% better) than the Classic Edition? No...of course not. The Classic Edition is still a very nice filter; far ahead of the inexpensive alternatives that are out there. At $50 for a 1.25" Classic OIII (LF3040-C) it is a screaming bargain. Sorry, no 2" Classic OIII's, they are already gone. We do, however, have the 2" Econoline OIII (LF3045E) for only $50. Not as good as the Classic, but still better than most competitors and absolutely unchallenged at that price.

 

I know people are waiting for scans, charts, numbers, and analysis...that is coming. We are just really swamped here at the moment and we want to put out only quality information.

 

Doug

Slightly off topic (but still discussing filters), does the latest Lumicon UHC filter cell have "Gen3" on it? How do we distinguish the newest UHC filters from the previous offerings? If I'm late to the party, my apologies. I'm still not clear on this, however.

If that paragraph refers only to the OIII filter, and I assume it does, then it does not answer my question.

It applies to UHC too.

Yes, the New TeleVue Bandmates in Nebustar UHC, O-III and H-ß have been at dealers for a little while.

TeleVue has the "no red" philosophy in filters.

They're made by Astronomik in Germany, but are a little different than the equivalent Astronomik filters.

I have test lab spec, and I'll be interested in comparing the results with the new Lumicon O-III.

I'll be watching for info. Looks like a new generation of these type filters.

If so, good. I didn't read it that way, though. The new UHC may indeed have the "Gen3" on the filter cell but that post didn't make that clear to me.

Lumicon should crow.

Tested specs of my sample Gen.3 O-III:

 

New Lumicon Gen.3 O-III 2018   11nm band width 494nm-505nm FWHM

Output % Hß 3.5   O-III (1) 95.1   O-III (2) 94.7  H-α N/A 

Excellent specs.

 

Tested in the field--excellent contrast on O-III nebulae.

Will you please post the curves for the old O-III and UHC filters so I can compare my old Lumicon filters with the new.

Here is a scan of a slightly older (pre OSI) Lumicon over the relevant range:

487.698 16.67
488.048 20.07
488.398 23.53
488.749 27.03
489.099 30.88
489.449 34.29
489.799 38.03
490.15 41.87
490.5 45.25
490.85 49.17
491.2 52.52
491.55 56.47
491.9 59.54
492.25 63.24
492.6 67.17
492.95 70.09
493.299 73.11
493.649 76.03
493.999 79.05
494.349 81.69
494.698 84.27
495.048 86.13
495.398 87.08
495.747 89.01
496.097 89.88
496.446 91.07
496.796 90.72
497.145 90.73
497.494 91.3
497.844 89.8
498.193 88.84
498.542 86.55
498.891 84.57
499.241 81.05
499.59 78.37
499.939 74.88
500.288 71.51
500.637 68.31
500.986 64.25
501.335 60.3
501.684 56.89
502.032 52.94
502.381 49.15
502.73 45.81
503.079 41.98
503.427 38.1
503.776 34.36

There is also a significant peak near 700nm.

 

11nm bandwidth 491-502nm

transmission at 495.9  about 89.5%

transmission at 500.7nm  about 67.5%

not good.  The curve is misplaced.

 

I don't have the scan handy from the 2005-2010 period my older Lumicon is from,

but the O-III line transmissions were 94.9 and 95.7% respectively, with a 12nm bandwidth (what I wrote on the package after the test).

 

For a comparison curve to be relevant, you'd have to know when your filter was made.

Don,

I own a DGM "npb" filter and I would like to complement with an OIII filter, Would you say that it is the best OIII filter that can be purchased today?.

Regards.

 

Víctor

Unsure of the answer to that.

It is certainly one of the best, along with TeleVue and Astronomik.

All are within a few percent on transmission and have essentially the same bandwidth.

Certainly it is a good performer in the field, so it would be a good one to complement the DGM.

Amongst the OIII’s, are the TeleVue and Astronomik the same, but rebranded filter?

 

I think the top end of town are virtually inseparable, so buy any of these with confidence. I’m a huge TeleVue fan, but have had a good experience with Lumicon filters, and that’s whats in my case.

Yes, I have tests for both.

The new filter:

--has less long wavelength transmission in the 650-750nm range than the old filter (OOB)

--has a higher % transmission

--has a slightly (1-2nm) narrower bandwidth.

 

The old filter was my "reference standard".  No longer.

Though both are superb (2009-2010 version and 2018 version), my new reference standard is another filter, but it is

not "visually significantly different" from the 2018 Lumicon Gen.3, which is an excellent filter!
