Still enthusiastic about my 5D3 but...Did some night sky photography last night and detected in all the frames black shadows around certain star clusters, no matter what ISO setting it was.

This is a result of oversharpening. What you are seeing is so-called ringing artifacts. Turn sharpening down and your problem will be gone.

Kind regards,
