Note that background subtraction does not itself locate any object or trim away background: after you have done the subtraction you need to do that. In your case, you essentially have no background and should proceed directly to locating the object.

See my Image Segmentation Tutorial for guidance on how to threshold a bright object on a dark background and then crop out that bright blob.
