I was in Big Bend last Dec with the 23 mm F4 and GFX 100. I shot a bunch of single shot astro. This one was 20 seconds at F4, 2000 ISO. I had to export it at 70% quality jpeg i LR to get it down to 50 MB so I could post it here. I think F4 is too slow for astro single shot.

On the raw at 100%, you can see star trails even at 20 seconds.

Without moving the camera synchronized with the stellar body you’re working against the laws of physics to get round stars no matter how short the exposure. The flip side to that is that then you then introduce movement into the landscape.
