1. An optical telescope with a micrometer is used to precisely adjust the polar axis of an equatorial radio telescope and any precise dial and clock will not be needed.

2. Made with data from the Nordic Optical Telescope in the Canary Islands, the composite picture shows extended emission from the nebula.

3. A typical optical telescope might have adiameter a few million times the wavelength of the light it is collecting.

4. This mosaic of M31 merges 330 individual images taken bySwift's Ultraviolet/Optical Telescope.

5. Now you take an optical telescope and you look from the ground,(Sentencedict) and now you see the optical spectrum of the donor.

6. The performance of optical telescope and TA(telescope array)as optical terminal in laser inter-satellites communication is researched.

7. In 1990, the first space-based optical telescope, the Hubble Space Telescope, was launched, providing the deepest, most detailed visible-light view of the universe.

8. This is the most advanced optical telescope in the world.

9. This mosaic of M31 merges 330 individual images taken by the Ultraviolet/Optical Telescope aboard NASA's Swift spacecraft.

10. In this paper, an anti-shake system is designed for small optical telescope, which has a compact size, low power consumption and good anti-shake effect.

11. Last week, scientists at several academic institutions used a large optical telescope to check the spectral properties of the drifter.

12. The relationship between residual wavefront phase error and frequency response in an adaptive optical telescope is analyzed.

13. It's the longest exposure that's ever been taken with an optical telescope.

14. Finally given are our detailed work results. We get the FWHM and EE of the Yunnan Observatory 1m optical telescope.

15. Stray light analysis is one of crucial technologies to ensure the image quality of Lunar-based Optical Telescope (LOT).
