Pixinsight - dark stars

I've just commenced on the long journey of learning how to drive PI.

I have a range of questions - which I may bore everyone with at some stages.

For starters, I have an odd experience.

Raw images when displayed in PI have a dark spot near the centre of all bright stars. In especially bright stars, this covers up to a third of the star.

I had thought it was a result of the minimum/maximum clipping process when calibrating images but its there in uncalibrated images too.

This is very odd - I haven't seen this with Maxim.

Images are taken with a QSI 583 using Maxim.

Has anyone else encountered this before?
