7 - 8nm narrow band versus 12nm narrow band filters

I am currently using Astronomik 12nm narrow band filters for imaging. I am thinking of some changes so I was wondering if the Baader 7 - 8 nm narrow band filters were going to be ok for a 110mm f6 refracting scope?

I also have a GSO RC8 that I plan to use soon, too. Are they going to be ok in that as well?

Decep,
I am sure they will be. I switched from the 12Nm Astronomiks to the 7-8Nm Baader versions, without a hitch.

I thought even at 3Nm things only got problematic at around f4 or lower ?

Thanks guys,

That is good news. Looks like it will be full steam ahead.
