Museum of Time
a trip to the beacon
 
On the east tip of the island stood an old beacon. Here you see it a few weeks before it was taken down to prevent the approaching sea from eating it.

A small sandy trail leads to the beacon on the "Boschplaat" - a bird sanctuary.
When I went there, it was overcast and so dark that it took well over 5 hours to finish the 11 kilometers long trail.

Luckily the sky cleared on arrival and at the end of that beautiful night, the Moon and Venus appeared in the sky just before twilight started.
 
During the night a single photograph was made with an exposure time of six hours.

As earth spinned around her axis, the stars made circular trails around polaris, the north star. Well, not all stars made circular trails: near the horizon clouds and cold air over the northsea bended the light of some stars upwards.

The bended startrails to the lower right of the beacon belong to the big dipper (ursa major, grote beer) and many stars left of the beacon belong to the milky way.

The orange light near the horizon is ionospheric nightglow: sodium (Na) atoms at a height of 100 kilometers in the atmosphere that weakly glow during the night.
