Hi,
A standard DSLR has an inbuilt filter which cuts down on the amount of Ha light that is picked up. Generally 60% to 70% of Ha light will be rejected. This very poor Ha response will turn the Tarantula blue and make it very difficult to get good results for things like the cone, horsehead etc.
Many people have this filter removed to improve the Ha response and this is called modding.
However modding can make it more difficult to take pleasing daytime snaps as a custom white balance needs to be set or the snaps will have a redish pink cast.
Without modding there are still many astro targets available so when starting out many people perservere with an unmodded camera. Canon used to produce an astro version of the 20d the 20da.
Cheers
Paul
