[wesdon1]

Anyone ever tried the Optolong L-Ultimate ? If yes, how do they perform compared to, say, the L-Extreme version?

I see what you are saying but the top graph doesn't end as such. the red line continues but I don't know what that means.

Plain CLS filters are mainly for visual use so don't have to cut off the IR, but CCD / CMOS cameras have a significant sensitivity to IR so it needs to be blocked otherwise image bloat will occur.

Thank You for educating me! I've totally re-done and re-titled the post!
