I have read that somewhere else as well and was thinking along the same lines, but on the Astronomic website it clearly says the cls-ccd is better for even unmodded dslr's and the plain cls is mainly for visual, so I am a little confused. On the links below scroll down to the suitability section on each page and have a read. It says that the cls is good for unmodded dslr's but the cls-ccd is very good for unmodded dslr's. Some input regarding this from some of you guys who actually use the filters would be great.
Thanks
