... The wind baffle fits closely about the telescope. It is supported by the building and protects the telescope from the wind and stray light. With the wind baffle removed, the secondary truss and interior light baffles are visible. The interior light baffles consist of the secondary, conical and primary baffles (top to bottom). ... The conical baffle (center) blocks stray light paths that would otherwise have to be intercepted by the primary and secondary baffles. ...

This radar image of 2007 TU24 was obtained on January 28, 2008, about 12 hours before the asteroid's 1.4-lunar-distance pass by the Earth, from an observation that used the Arecibo telescope to transmit a 300-kilowatt beam of radio energy toward the asteroid and the Robert C. Byrd Green Bank Telescope, (GBT) in West Virginia to receive the echoes. The image summed echoes recorded over about three minutes. The intrinsic resolution of the image is about eight meters (25 feet). ...

Another method is to take very fast exposures of an object; in effect taking images faster than the seeing can blur the image. ... A third, relatively new method, is to try to detect just how the seeing is affecting the image, and actually warp the telescope mirror to compensate. ... The advantage of the second method is that it's easier to make many small mirrors than one big one. ...
