Hi Everard. You won't get Ha with a 10" scope. You just can't get a Ha filter that big, or if you could, you wouldn't be able to afford it.
For that aperture, you are limited to white light and as Eric pointed out, there's an article on how to build your own which is what I did. That will show you sun spots and minor surface granulation at higher mags and good seeing.
To see flares and prominenances, you need H-a, and your cheapest option is the PST at under $1000 (for 40mm aperture). You have to spend much much more than that to get larger apertures, and even then, it's still only 60mm aperture.
What you can see through a PST is actually quite good. It's just a matter of practise, and tuning in the filter to show the detail you want to see. I certainly wouldn't call it limited.
