Probably just my lack of knowledge of what you meant by ghost....
I am still learning myself. Now I see it is called NGC3242 as your post stated you were having a go at planetary and you were having issues stacking I assumed (incorrectly) the ghosting was a problem you had. Now I have learned there is a nebula called the Ghost of Jupiter. You learn something new everyday.
