At least that's my explanation/belief.
It's primarily because it over-saturates the imaging device. As an astro-photographer myself, it's extraordinary difficult to get a nice-looking image that shows both the nucleus and the spiral arms of a galaxy, because the nucleus is so much brighter. You end up either with an over-exposed nucleus and nice-looking spiral arms, or a correctly exposed nucleus and almost invisible spiral arms.
