Got dark frame to work on FireCapture but not flats so Newtonian rings (altering dark and white bands) still present – also some dust bunnies!

My picture turned out as below….ImPPG allowed me to move the black point to the lowest brightness pixel present – sprad out data BUT also left the impression that there are black flames on the sun’s surface(!) – or, as my daughter Hannah suggested, makes it look like the sun has blackheads (acne vugaris).
I have therefore inverted the image in Photoshop CS6 below. Which image do you prefer?
