Here's the best results .. after some Photoshopping of course.
I started here:
Which was me, forgetting I had left the camera set to 3200 ISO! One of those happy mistakes! Look at all them stars!! Everything is yellow due to the sodium streetlamps of course - next time I do this, it's backyard for me! 206 seconds (3:26) at f/4.0, ISO 3200. Then I moved onto this:
Which actually caught a bit of the milky way there! (top left cnr) This one is 219s (3:39) at f/4.0 and ISO 400. So then of course battery went flat, so went inside for charging, came back out and just as it was clouding over, got these:
123s (2:03) at f4/5, ISO 400
163s (2:43) at f4/5, ISO 400
So I have so far stabilised the mount, and got a minute of metronome clicking (60bpm) for my mp3 player, so I have a stable mount and WAY more accurate timing .. however I do end up outside for hours, in the cold, listening to clicks :)
According to the met service, we are facing rain until thursday next week :( But I live in hope!
All in all a good night! :)
