another futile attempt II

  

  

  

  

  

  

 

Unlike other optical devices this viewer focuses on different things in separate locations.
It is made to simultaneously observe the sky and measure the growth of a tree, using a specially developed measuring scale.
In the gallery it points at two small objects placed at both ends of a wall, one containing an image of a starry sky, the other an image of the tree.
