Roundabout

Now playing with startrails - The Nikon D7000 has a built in interval exposure function. The exposure details for this image are 60 shots at 30 second - f6.3 (ISO 200, 10mm lens) on manual with an interval setting of 32 seconds on the camera - the interval must be longer than the set or expected shutter speed. (If you have left exposure bracketing on set at 3 like I did - silly! - then the manual max becomes 8 seconds which I can sort of make sense of but which certainly confused me for a few minutes not to say about 25)

 

This was from my back garden which as you can see suffers from light pollution as does almost everywhere in south east UK. I set the camera up and left it alone on its tripod for just over 30 minutes (60 shots 32 second interval - hence a 2 second gap between each exposure). I have some more interesting sites in mind but don't relish sitting around in the dark for an hour or more waiting for the sequence to complete - I can hardly leave the kit there unattended!! Quite apart from the way loitering like that looks to the uninitiated it's rather boring!

 

Back to business - the resulting 60 raw exposures were batched through Nikon's ViewNX2 to jpgs and then I used the remarkable and free "Startrails" software - very easy to use - many thanks to the author Achim Schaller

 

I would have gone for a shot centred on Polaris (north star) but that way be street lights....

 

First effort not bad - feeling my way in....
