Dust donuts remain in integrated image

Adam,

What can I do?  Can LSPR help?  If so, how?  If not, what do you recommend?

    Better flats. 
    This generally is not a processing problem (assuming the images are calibrated properly.)
    At the donuts exactly the same in all calibrated images, or are there just some images that have them?
    The kind of processing you do to make them go away depends on that kind of answer. Sometimes it really isn't possible to completely deal with them... which is why the first statement is so important.
