The first two images are the closest I've been able to get of the Milky Way - at my latitude and this time of year it's not greatly visible as you only get the tail edge drifting above the horizon. At ISO 3200 I can just start to make out some of the denser areas in the middle of the image. Longer exposures and/or stacking would definitely help here.

Jupiter was just visible above the tops of the trees in our garden, and I tried a few variations of exposures and ISO speeds. The one below (ISO 3200, 15 seconds) was probably the best of the bunch:

I also tried out a longer lens, my Sigma 105mm, I definitely need some more practice with this one at night. 3 second exposures is just beyond what you can do at 105mm, so it really should have been 2.5s. The below image is the best of the few shots I took with it. Clearer image of Jupiter, but not as good imaging of the general starfield background:
