OK, gradually getting this together.  Here are the images.

This was taken setting up the Equatorial Mount, need to level it and align with Polaris.  The only item of gear I forgot was my little level.  The iPhone did that perfectly well.

As I was doing my first test exposures a car came from the South, behind me.  At that point any cars approaching from the South light up my position for quite a long time, at least a couple of minutes.

All these images were taken with the D800 on my Equatorial Mount using the 16mm f/2.8 ais fisheye.

This was @ f/4.0 for 30 seconds, ISO1600.  you can see the shadow of the tripod and a slightly ghostly shadow of me on the weatherbeaten grass.



This was taken @ f/5.6, 120 seconds, ISO1250.  Graham may be interested because the signpost is directing the traveller to Eskdale 3 Miles away.



Longer exposure of 240 seconds, a flash of my head lamp on the signpost reveals the text better, again f/5.6 and ISO1250.



Ambient lighting here, f/5.6, 240 seconds, ISO 1250



The next image was caught by my red head lamp, 180 seconds, f/5.6, ISO1250.



Finally, 480 seconds @ f5.6 ISO 1250 but with the Astro Mount motor turned off.



I took one exposure at f/8.0 but it wasn't much good because it was contaminated by my torch and a passing cars headlamps, but it was pretty sharp @ f/8.0 so I may try that again.

This is the location, I was in the Southern corner of the crossroads, the Lat-Long are of my camera position.
