My good friend & I seem unable to agree on which filter is best used for what. I am a little bewildered that my friend relies heavily on a OIII filter for Nebula's other than Planetary Ones.
I have owned both a UHC and OIII and found the UHC to be far superior when viewing most Nebula's.
I understand that not all nebulas are the same, and will do better with filters designed more specific to the light coming from that target.

My friend claims that it was here at iceinspace that he was informed that an OIII filter is best use to view Nebulars. I was quick to explain out of the UHC & OIII, that I found the UHC gave much much better results on targets like M42 Orion as well as Carina Nebular.
In fact, I was quite astonished at just how much more he was missing out, when using a OIII filter on the Carina Nebular after looking at it myself in his 12" Dobsonian. I too once owned a 12" Dob and when Using a UHC on Carina, I could see HEAPS more detail.
I find that the OIII filter cuts out WAY too much light on such targets I have mentioned. In fact I told him, it was at iceinspace that I was told a OIII filter was better suited to planetary nebulas.

He pulls out his OIII filter and points to the word "Nebular" on it. LOL ...
All I can say ... is the OIII is all he owns.

So ... I beg the question ...
Surely he would do much better to view M42 and Carina
NGC 3372 bla bla bla with a UHC any day over his current recommendation of a OIII???
Thanks In Advance ...
