Almost exactly two years after the first “wedding” between our main telescope and the dome building, we could celebrate the second “wedding” between the main telescope and its optics. This consists of the primary mirror, the secondary mirror and two large correction lenses. The main mirror virtually “floats” in the mirror cell on a cushion of air, which prevents the glass from bending and thus destroying the high optical quality. The optical adjustment is controlled by three electrical sensors, which carry only a small part of the mirror weight.
With this telescope we collect about 18,000 times more light than the human eye, which will have a corresponding effect on the observation results.
^-^ Congratulations!!! And those 4 bridesmen are also good~~
Hope I can eat their bridecake soon……
