Observation


We have used three different methods of Venus observation. Details will emerge upon clicking.

1. Direct observation using a solar filter
  The direct observation has been conducted by Team 3. Exact values could not be determined, as the observed image was too small.
2. Projection methods
  This method has been used by Team 2. A telescope has been used, through which we projected the image onto a list of paper. These values were the most exact, and because of this also the final time values have been derived from this observation.
3. Through a CCD sensor
  This way has been chosen by Team 1. In this case they employed a digital camcorder with a camera and the image was being projected onto a wall using a dataprojector. The CCD sensor had a resolution of 1.55 MP and the photographies located in the photo gallery have been taken using it. As a means of protection for the sensor a welding filter no. 14 has been used. Other features include a 10x optical zoom and manual exposition. In spite of employing modern equipment the results obtained, however, weren't as precise as those obtained using the telescope.
