They work absolutely amazingly. Especially when your mirror lens is an 8-inch Celestron with a mirrored Mylar solar filter over the aperture. My father took some astounding sunspot images in his time with that ol' Celestron.

Of course, the closest I personally got to astrophotography was taking images of the Orion constellation, and a couple of the moon—all with standard camera lenses.
