Here is a single 8 min shot of the Triffid Nebula, taken with the Astronomik CLS EOS Clip in filter, although its also available in 1.25" and 2" sizes also. Taken through an ED80, on an EQ6 mount, guided with an Orion Starshoot autoguider on an ST80. This image is untouched and as is.
i have recently aquired the Skywatcher 2" LPR filter, availble in the UK, and will take a shot through that also, and post the results.
The Astronomiks filter does a good job, but its a little too blue for my liking.
