10 STOPS! Why not just use your lens cap?

Adorama lists a 16x ND Tiffen Digital HT filter that Tiffen's website doesn't (?) See http://www.adorama.com/TF77ND12HT.html

That is allot of light blockage, I was only looking for 3-5 stops but 10 is allot.

The tiffen HT's are nice, and are easy to clean for a multicoated filter.

I want to get some movement in clouds/water during the day I'll check out Tiffen. I just found a 9 stop Hoya.

Hoya super HMC and HMC's are nice, but they are a bit difficult to clean in the field. Tiffen uses a titanium mix in their coating so you can treat it like a glass filter. I have a hmc filter, they do work nice. But not easy to clean.

What do you think if I stacked my CP, .6 and .9 ND filters? That's about 7 stops right? Will the image quality deteriorate more than a 9-10 stop ND filter?

Your .6 is two stops, your .9 is three stops, and the Tiffen 16x I mentioned is four stops. Ten stops would be for something like taking time exposures of the Sun.

Have you tried your .6 and .9 filters to do what you want? Did you get close? Were the results from the .9 significantly different from the .6?

Filters, especially inexpensive filters, can noticeably reduce image quality. Stacking filters, especially inexpensive filters, will reduce image quality A LOT! Since this is to record movement during a long exposure, the image quality degradation might not be noticeable, but flare may appear during your exposure that you didn't see when you first set it up.
