Looks interesting, any additional info on what this is?

If you click on the “Bright Stars” layer, you’ll see this labelled as “HR 1457”;

Bright stars saturate the detectors, so that’s why it looks all odd in the middle. It should just look like a dot; all the structure (the X shaped diffraction spikes, the sprays of light) are optical or instrumental effects. The circle in the middle, which looks really cool, comes from how the data processing software deals with saturated pixels.
