If you only plan to buy one filter the DGM NPB may be your best choice. It isn't expensive and works on a wider range of targets than the UHC and OIII filters individually. It is a very narrow pass band UHC filter and essentially is almost a hybrid UHC/OIII filter. It is also idealy suited to a scope of 12" aperture.

Good advice! I agree with John's comments as to the differences between them...I think highly of my DGM NPB filter...
