When I was using my 100d and modded 1100d I used the very powerful stretch tool in Nebulosity to bring out the detail. Then I used curves after that to fine-tune it.
If your camera is not modded you will be missing most of the Ha light.
Here are two examples of what I did with the 1100D. These were both Very early on doing Astrophotography.
Notice the short exposure times with the modded camera. Also I would have been using a CLS clip filter to reduce the skyglow.
First is with the 300mm Zoom lens. 10 x 30 Sec Subs
Second is with a meade SC8 prime focus 15 x 1 Min subs.
