Best OIII filter?

[cyborg421]

On FLO there is virtually no difference in price between the Baader OIII filter and the SW one but it seems from the comments that the Baader is much the better one?

The Baader has a narrower pass-band than most others so it is more aggressive and darkens the view much more. You may like this or you may not. Personally, I don't. I prefer the brighter image you get with the Skywatcher, Astronomic, Castell, or Lumicon filters.

I use a Castell 1.25 O-III filter and find it's excellent.
