EFW Mini light leak

Discovered a huge light leak trying to make a set of Darks during daylight hours.
Finally tracked it down to the pop-rivet that holds the white disk on. Covered it with black tape, leak gone.

Others on ASI Camera group on Facebook reporting the same issue

Both images from same location, scope, camera, gain, temp, duration. Different targets. Single FITS subframe stretched, resized, and saved as jpeg

I now know is the motor and the "pop-rivet" is the motor shaft). Other users have shown the leak is around the disk.

Tailspin45 Thank you, I got it, and forwarded it to our team.

Forgot to include this "smoking gun". I tried to create Flat frames for calibration during the day and the Flats looked like this. That's when I knew I had a leak. I'd always created the flats at night and the leak wasn't obvious.
