Gemini telescope (GEMINI) is a US-based international equipment (including what makes a good telescope, the United States accounted for 50%, the UK 25%, Canada 15%, 5% in Chile, 2.5% in Argentina, Brazil accounted for 2.5%), from the American University Astronomical Union (AURA) responsible for implementation. It consists of two 8 m telescopes, one on the northern hemisphere, one on the southern hemisphere, in order to carry out systematic observations throughout the day. Its primary mirror active optics control, tilt mirror secondary mirror for fast correction, also through the adaptive optics system of the infrared region close to the diffraction limit. Large Sky Area Multi-Object Fiber Spectroscopy Telescope LAMOST (GuoShouJing) which is China has built an effective clear aperture of 4 m, a focal length of 20 meters, the field of view of 20 square degrees of the star ceremony reflecting Schmidt telescope. Its technical features are: 1. The active optics technology in reflecting Schmidt system for real-time tracking celestial spherical aberration correction movement in telescope what kind of good, to achieve large-caliber and large field of view of both functions. 2. Spherical primary mirror and a mirror are used splicing techniques. 3. Multi-Object Fiber (up to 4000, only 600 general telescope) spectroscopic techniques will be an important breakthrough. LAMOST the general survey of galaxies and other limiting magnitude pushed to 20.5m, higher than about 2 SDSS plans, to achieve high-quality general survey telescope spectrum of price 107 galaxies, the number of observations that target by an order of magnitude.
