Thanks mates, I appreciate your comments!
Jim, I used a vr 70-300 on a tripod (of course) at 185mm, f/9, 30 seconds, Manual settings for time and f-stop, Matrix metering, ISO 200 and all pics were shot with RAW adjusted with ViewNx and converted to Jpeg.
Second two pics I zoomed in to 300mm and f/6.3 at 30 seconds and ISO 400 because it´s been a little darker and I wanted the pics to be a bit lighter. Same as above.
Swep
Edit: I forgot to mention that I set the selftimer to 10 seconds and had a mirror delay of 1 second to avoid vibrations.
