Why the lowest ISO? I shoot the night sky at 1600 to 3200 ISO.

Use a tripod and a long exposure. Maybe 15 seconds. Use manual mode and use the widest aperture and lowest iso (probably iso-80) and set your focal length to about 75mm. You should get something like this. This wasn't taken with a P520, but those are the settings I used and it should work the same on your P520. Note that with the naked eye I only saw about a dozen stars in the sky. The camera sensor picked up the rest.
