We describe an optical device consisting of a Universal Birefringent Filter and a Fabry-Perot interferometer used in tandem to obtain monochromatic images of the Sun in the visible spectrum (between 4200 and 7000 A). The spectral resolving power is a

Mercury's transit on the solar disk offers ideal conditions to determine the stray light level of instruments. We present here the results on the stray light level deduced from the obser- vation of the Mercury transit on 2003 May 7th at the secondary

While site testing for the establishment of a new solar observatory, measurements of the microthermal turbulence as a function of the height were performed over the island of Tenerife (Canary Islands). These measurements were carried out with balloon

In this paper we describe an experiment in which we measure the energy of the atmospheric turbulence up to an altitude of 20 000 m. The measurements have been performed simultaneously by a remote optical system attached to an astronomical telescope a

Solar spectroscopy on two dimensional fields is strongly needed to obtain a better understanding of the physical processes which take place in chromospheric and photospheric plasmas. Up to now several devices have been used to obtain strictly monochr
