Paul, all the EXIF data is intact if you have an EXIF viewer installed in your browser. I use EXIF Viewer, a free add on for Firefox, not sure about other browsers.
The basic settings were 20 - 30 second exposures, ISO 6400, f4.0. Fairly standard for me for star shooting. If you don't want as much Milky way or other stars you can just lower your ISO to get the look you want. Lowering ISO lowers the amount of ambient light you will get in your shot.
Here are a couple more from last weekend.
