Just had a quick look at the full sized image, focus is out a bit, note the double spikes on the lower bright stars. The stars to the left of the image look worse but wont be as bad with better focus. There might be a bit of tilt on your camera, possibly the camera is not sitting square in the focuser tube, but it could still be a collimation thing. I have an RC6" but have only ever had to tweak the secondary a very slight bit. Work on the focus and go from there.
