5 of 5 Outstanding Service from a top-rate company December 5, 2020
Reviewer: Terry Trees from New Kensington, PA United States  
Filter arrived in mint condition and in record time from west coast to western PA- Cannot comment on filter performance until after 12/25 because Santa intercepted the package.

5 of 5 Great product. Better service! October 23, 2019
Reviewer: Jay Mills from New Albany, MS United States  
We all know the quality of fit, finish and function of Lumicon's standard in the telescope marketplace.  This one did not disappoint!  Ink black backgrounds and super definition in the nebulae structure.  You'll see nebulae that are only hinted at with other's filters.  It really is like getting a totally different scope!  As for the service, Don has always been generous with his experience and technical knowledge and any gear that I've purchased from EyepiecesEtc.com arrives quickly, packaged with more than ample packing to insure it's safety.  Very pleased!

5 of 5 Very useful accessory October 7, 2019
Reviewer: Santiago from Baton Rouge, LA United States  
In clear and clean night but with Moon at 63% in a heavy light polluted area:

200mm SCT: M8 was a small spot without filter. Both the OIII and the NPB gave though a spectacular view. The OIII revealed the Veil nebula, faint but otherwise impossible to see. Planetary nebula NGC6905 & 6826 where nicely visible ONLY with this filter, no hint at all w/o it.

Even worse day (haze) w/ an 80mm. Dumbbell and M57 where not there (!) until I put the OIII gen3 filter and really popped out, like ON/OFF button!

Stars are easy to focus with the filter.No problems at all to insert into my Baader diagonal. It works as a moon filter too!

I put the filter (batch 09/2019) into a spectrophotometer and the result is what the specs and the manufacturer test report promised. ~97% transmission for OIII bands, 12nm width at T=50%  (492-504), 18 nm width T +0.5% (490-508 nm).

Just in case it's not clear: I love it.

The experience to buy it in eyepiecesetc.com was excellent.
