The sky inhabitants - the constellations. ... The constellations of Zodiac. The constellations of Zodiac are very popular. ... They were counted from the point of vernal equinox. ... As a result all the Zodiac row of constellations as if displaced in the two positions the count traditionally begings from the constellation where the point of a vernal equinox is. ... That is why the Sun comes to each Zodiac sign two - five weeks before the time when it comes to the constellation of the same name. ...

... The Science Operation Department is composed of Astronomers, Telescope Instruments Operators(TIOs) and Data Handling Administrators(DHAs). ... Astronomers have proposed several methods to quantitatively measure the amount of turbulence above the telescope, which the most common ones is Differential Image Motion Monitor (DIMM). In optical testing, the Hartmann test is the common method to test the quality of optical components. ... Hartmann mask consists of 48 lenses. ...
