I have a ZWO 2600 which will live on my 80 mm Espirit and I am thinking about a dual filter or tri filter of some kind ...however these filters it seems are for light polluted regions and I am in a reasonably dark site...is there any point in getting a filter and if so what one?
It seems to me that such filters brings you c1lose to the benefits of narrow band imaging which appeals...any advice gratefully received.

Hi Alex,
Your sky is incredibly dark: Bortle 1 SQM 21.99 !!!! (based on the stated Tabulam location in Lightpollution Map World Atlas 2015 -see below),
you don't need any light pollution filters, unless of course you specifically want to do narrowband imaging with your 2600MC OSC colour camera and some dual/tri band filters and split off the channels, but don't you also have a 2600mm that you could use if you wanted to narrowband image?
Best
