OK, now you can tell me what I've done wrong with them
Nice first images. I can only summise about the colour problems. DSLR unmodded are quite sensitive to the OIII colour range (Jade/Blue/Aqua) and not terribly sensitive to the Ha (red colour range).

A classic mistake when imaging with an unmodded DSLR is to try and add the red which is often missing with DSLR images by using the colour balance and pushing up the red which in turn adds a wash to the entire image. A hard one to overcome without modding the camera.
