Even though the night sky is heavily polluted by the lights of Oslo and its suburbs, there are many stars visible to the naked eye only a few kilometres out of the city, like here from Svartskog. Even more so when using a camera with long exposure and high iso.

This is due north, which is very visible when all the shots are stacked, forming trails around a point in the sky – north.

This is a stack of 1011 images, covering several hours between 18/19 April. The past winter has been completely overcast, so I am truly grateful that the sky finally is clear before the bright northern summer overpowers all stars in a few weeks.
