Here's an example of one of my very first Eta Carinas using the DSLR, along with the images histogram.
Looks very similar to yours. But notice the histogram. There is a little bit of white clipping at the right hand side and the full white range has information in it, but the left hand (black point) end isn't clipped, though there is information right to the end. It's not the perfect example but gives you some idea of what to aim for. A better exposure would have had the bulk of the tonal range more towards the middle of the histogram, though that would have probably led to more clipping at the white end. BTW this is the unprocessed image.
