What's wrong with my A6000 night shots?

[aziggs]

I've used the A6000 successfully in the past to shoot the milky way by an extremely simple solution....putting it on a night mode and steadying the camera on a rock or backpack. I must've accidentally changed a setting because now when I do the night program mode with a 30s shutter, the photos come out looking like day time! Even when it's been pitch black outside. My example photos are attached. I know these are slightly out of focus, but it's the exposure that's driving me crazy. Any help?
