I agree if it's only the dust bunnies, but what about the flat field? There's possibly some vignetting in the system, this will not be corrected??
I was under the impression that all flats should be taken with the camera/ optical system which will take the lights??
Someone suggested rotating the camera and doing a median average????

Hi Merlin66,
I did not read enough and did not see you have a PST. So I guess the only way to make some flats is to cover the scope with a piece of paper when shooting the sun in order that you do not get any detail but your dust bunnies are iluminted enough to be part of the image.
Sorry first answer was stupid fomr my side
