Layout of the telescope-spectrographs
configuration for the Total Solar Eclipse 11th August 1999. 13 fibres were
used in total. Figure 1 was taken with the high resolution spectrograph
(Resolution 0.5nm, Range 530-670nm), while figure 2 was taken with
a low resolution spectrograph (Resolution 3.5 nm, Range 480-680nm). |

August 1999, minutes after the total eclipse. It was taken with the high
resolution spectrograph in the wavelength range 530-670 nm |
