Typically an un-modified DSLR can only capture about 20% of the red spectrum due to the internal filters. A wide field Ha shot of rhat same area will show you much more, and many hidden structures. The whispy clouds you see in the LMC are usually Ha emission nebula structures. It will not help much to put an Ha filter on your DSLR as the internal filters will still block most of it. An astro modified DSLR will allow about 5x as much Ha light through and this will givevyou the whispy structures you seek.

I was thinking of modding my cheap Nikon but that would basically rule it out for any other kind of photography, yeah? And I'd have to use filters to get colour images, and basically quadruple the capture time to get the different channels? Do I have that right? Or am I supposed to just add Ha to the unmodded DSLR capture?
