The idea came to him that they could mount the required corrective components on such a device that would allow them to be inserted into the tube before being folded out on robotic arms to the required position to intercept the beams of light from the secondary mirror, correct and then focus them on the various scientific instruments.

MagAO was originally intended for the Large Binocular Telescope (LBT), but the secondary mirror was damaged before it could be installed. The project leader Laird Close and his team were able to repair and repurpose the broken mirror for use on Magellan II. As built for the LBT, the original MagAO mirror had a diameter of 36 inches (0.91 m).
Under-cabinet light – mounted below kitchen wall cabinets. Display Case or Showcase light – shows merchandise on display within an enclosed case such as jewelry, grocery stores, and chain stores. Ceiling fan – may sometimes have a light, often referred to as a light kit mounted to it. Ceiling fans with built-in lights may eliminate the ...
French cleat on a wall (left) and correspondingly on a shelf to be hung up (right) A French cleat is a way of securing a cabinet , mirror, tools, artwork or other objects to a wall. [ 1 ] It is a molding with a 45 degree slope used to hang cabinets or other objects.
The Nasmyth design is similar to the Cassegrain except the light is not directed through a hole in the primary mirror; instead, a third mirror reflects the light to the side of the telescope to allow for the mounting of heavy instruments. This is a very common design in large research telescopes.
The telescope design has two 8.4 m (330 inch) mirrors mounted on a common base, hence the name "binocular". [1] LBT takes advantage of active and adaptive optics, provided by Arcetri Observatory. The collecting area is two 8.4 meter aperture mirrors, which works out to about 111 m 2 combined. This area is equivalent to an 11.8-meter (460 in ...
President-elect Donald Trump listens to Elon Musk as he arrives to watch SpaceX's mega rocket Starship lift off for a test flight from Starbase in Boca Chica, Texas, Tuesday, Nov. 19, 2024.
When the two mirrors are on one mount, the combined mirror spacing of the Large Binocular Telescope (22.8 m) allows fuller use of the aperture synthesis. Largest does not always equate to being the best telescopes, and overall light gathering power of the optical system can be a poor measure of a telescope's performance.
