I have 4 2" eyepieces plus a televure 2x barlow at the moment, the next one I will get will be a 15mm or 12mm eyepiece. Sorry the 20 sounds great but just out of my range.
So if I only bought 1 filter now what should I get firt the O111 or the ultrablock.

Houghy,
I would get the DGM Optics NPB filter.
As I said Phil Harrington rates it as the best Narrowband/UHC type filter he has ever used. I have a copy of a review Phil did on 25 different filters and the DGM NPB filter came out very very favourably. Unfortunately I can't be much more specific than that because the article has not gone to print and will do so in a future issue of an American Astronomy Magazine. The DGM NPB is very cheap and very good. Failing that if you want a top class excellent filter I would get the Astronomiks OIII from Bintel followed by the Astronomiks UHC from Bintel. If you are budget conscious I would get the Orion Ultrablock from Joe O'neil in Canada
