SALT launching on 11 November
The Southern African Large Telescope (SALT) will officially be launched on Thursday 10th November. SALT is the largest telescope in the southern hemisphere and equal in size the the largest telescope in the northern hemisphere.
It's the biggest OPTICAL telescope in the Southern Hemisphere.
Almost all radio and mm-wave telescopes are bigger than it, and have been for decades.
It's still to be fully calibrated. That's what first light literally means, the first astronomical light to pass through the instrument, so that you can start the shakedown tests and calibrations.
Pedantically speaking, SALT isn't the largest telescope in the southern hemisphere. There are plenty larger -- for example, the Parkes Observatory in Australia is 64 meters across. It doesn't match the size of the largest telescope in the northern hemisphere, either. To do so it would have to be as large as Arecibo, 305 meters across.
