+1 if you've got lots of noise and/or distorted/streaking stars these tools can fail. In difficult cases i use the Dynamic Alignment tool to register the first five frames then integrate them to give me a cleaner image I then use as my source target image for StarAlignment or batchpreprocessing to register all the frames against. Or in worst cases i just use DA for the whole registration process. Before all this I tend to run the Subframe Selector script to find the worst frames (where the stars are most distorted) and weed them out first so I'm not fighting vibration wiggles in the source.
