BluTuna, remember that this is full frame, and I am actually seeing a little bit of trailing in the corners already (I don't think it's Coma, because the direction is just what one would expect for trailing). What I am saying is that these "rules" are not accurate for high-resolution sensors. They are probably fine for a 12-14Mpix camera, but for our 24's, you can't use them unless you only want to share on the web or similar.
And this of course puts big strain on your camera's high-ISO performance. There is a method where the guys take 5-20 photos, then stack them in Photoshop using photomerge (in two seperate steps, one for the foreground and one for the stars, with the unwanted areas painted out), and then using a median filter for noise reduction.
There is a tutorial here:

And also some inspiration and other ideas here:

But for me at the moment these techniques are too advanced. I use Lightroom exclusively, so can't stack. Not sure for how long this will continue though. But my feeling is that if you are not prepared to use these types of techniques, you need a full-frame camera or you will only frustrate yourself.
So just pack me in as well when you go!
PRWin, f4.5? That's at least a whole stop darker than these, which are all at f2.8 and either ISO5000 or ISO8000?
Thanks.
