small scuffs on cls filter, should I replace it?

[billhinge]

Hi all

Planning to do some photography with a diy modded canon dslr this christmas, I work away from home so Christmas is my next major time off. I'm putting my kit back together from out of hibernation from last 2 years.

When I dug out my 2" cls filter from storeage I noticed that there are about 3 very small scuff marks on the surface. Will this have a noticeable impact? ie does it need replacing with a uhc filter or will the scratches be out of focus? Just putting together a little shopping list ...

regards

Yes. And the zillion particles of dust in the air, plus the diffusing effect of water vapor over kilometers of air layers...you get the picture.
