Well, I am back.
I managed to shoot a number of halfway decent pictures.
Currently I am trying to find out what part of the sky is actually visible... :-)
I cannot yet correlate my photo's to e.g. stellarium's rendering of that date/time/location.
I went as high as ISO400 and 20 seconds exposure.
Noise was not too bad, although ISO200 is of course better but shows less stars.
Used a custom timer to avoid shakiness.
No stars show the movement of the sky, as far as I can tell.
So I am fairly happy! :-)
Thanks!
