Taken last night, this is a panoramic "stitch" of six images. Each of the individual images are 3 minute exposures, meaning that this photograph was taken over 18 minutes (plus a further 3 minutes between each shot for in-camera processing).
The original version is a 36 megapixel image but has been reduced to 18 megapixels in order to keep download times reasonable. The view is of the Thunersee from the Spiez vineyard hill, looking towards Interlaken; one of my favourite views in the world. If you have a broadband internet connection and you're one of my contacts, the original version is quite something.
