Telescope Mounts . ... I just collected all the information I used in considering what kind of telescope mount I wanted and made a web page. ... A very important aspect to using a telescope is the mount. ... An altazimuth mount is a design to hold the OTA and allow the user to guide the scope by using two motions. ... The newest GOTO telescopes can do all of this without equatorial mounts and polar alignment because the computer can be programmed to know the position of the scope by using guide stars. ...

... In this case, the main vortex in the Benard cell is decomposed into smaller ones as a result of ten perioddoubling bifurcations. It is shown that the resulting turbulence is coherent and determinate; the fractal character (local selfsimilarity) of its spectrum is found. ... It is shown that the real atmospheric turbulence is the result of mixing of different coherent structures. ...
