Narrowband and O-III filters

I am planning to buy narrowband and oxygen-III filters. Do you have any suggestions which brand to choose or do you know some webpages with reviews?
Thanks

Hello Marcin... 8)

For Narrowband, get either the Lumicon UHC, or the Orion Ultrablock as a second option.

For O-III, get the Lumicon one...


Hope this helps,

For price alone I'd recommend both the Orion Ultrablock and OIII. I had an Ultrablock with SCT threads which I liked a lot, but I need to replace it with a regular 2". I bought a TV OIII on sale which I use regularly, esspecially on the Veil, but compared to other OIII filters the TV seems to let a little more light through. I think it is a pleasing view, but others have commented that it wasn't a "true" OIII filter.

I vote for the Astronomik filters. They are the only one that has been able to keep up my old Lumicon filters. The new Lumicon filters are not as good as the old ones were. Of course try before you buy, if you can.
