Ha filters with color ccd's / DSLRs?
Anybody know if a Ha filter will work for imaging using a DSLR or a Bayer Matrix CCD?

I love the HaRGB images that have been displayed recently, and would like to give it a go when all my new bits and pieces arrive... So, Should I add a 2" Ha filter to my 2ft long order? and if so, whats the difference between all of them, 7nm, 5nm etc Obviously, the wavelength of light it allows through is the difference, but what is the effect on the image?

Cheers.
Alex.
