Weird pattern in GFX50r astro shot

Here is a single shot astro on a GFX50r with the 23mm/4 lens. I just noticed the weird aliasing artifact (circular interference pattern running from top to bottom). Or is it? My Sony A7RII never showed anything like this in astro shots. Where could this weird pattern be coming from? Is it some interference pattern from internal reflections. I am baffled.
