I have looked, but everything is different, they use their own versions of different filters. I did look alot at one guy who was obviously in france, and he used spectroscopy to show what the pass filters do. Astronomik proformed the best.
Though thats why i have come to this part of the forum, its not because im lasy its because with every clown on the internet confusion often sets in. and in such a specific area that i have querys with, i just want to get other peoples honest opinions before i go and buy a decent filter.
Im going to try and get a hold of these filters before i do buy one so I can see the exact difference they make.
Further to this subject, i will more than likely take the photography leg, though as i cant afford what i need just yet im forced to use what i have. so make the best of it i say!
