"Man must rise above the Earth - to the top of the atmosphere and beyond - for only then will he fully understand the world in which he lives."
Socrates ca. 450 B.C.

The "Big Five" segmented mirror telescopes:
Keck I (1993) and Keck II (1996) - Hawaii, USA
HET (1999) - Texas, USA
SALT (2005) - South Africa
GRANTECAN (2009) - Canary Islands, Spain

The eye-brain is an amazing detector:
- removes aberrations (clever image processing; stereoscopic; scanning)
- capable of a 1,000,000,000 dynamic range ( < 100,000 for a CCD)
- ~0.5 arcmin resolution
- a two-dimensional video detector (~30 frames/second)
- capable of photometry: measuring the brightness and colour of stars

The next big thing: the largest astronomical CCD camera for the Large Synoptic Survery Telescope (LSST)
- a wide-field (3.5°) 8-m telescope surveying 20,000 sq deg of the southern sky
- will survey to V=27.5, cataloging 1010 stars and 1010 galaxies
- detector consists of 200 4k x 4k CCDs - a 32 Gigapixel camera
- each 15-second exposure reaches V=25
- only two seconds to readout entire detector (many parallel reads)
- will produce 32 TB of data per night!
