Exempel på hur man kan använda ALTAZIMUTH i en mening

• Dobsonian telescopes: John Dobson popularized a simplified altazimuth mount design for Newtonian reflectors because of its ease of construction; Dobson's innovation was to use non-machined parts for the mount that could be found in any hardware store such as plywood, formica, and plastic plumbing parts combined with modern materials like nylon or teflon.
• Also, for astrophotography, the image does not rotate in the focal plane, as occurs with altazimuth mounts when they are guided to track the target's motion, unless a rotating erector prism or other field-derotator is installed.
• These were controlled from a trio of hemispherical, glazed, gunner-manned "astrodome" sighting stations operated from the pressurised sections in the nose and middle of the aircraft, each housing an altazimuth mounted pivoting gunsight to aim one or more of the unmanned remote turrets as needed, in addition to a B-17 style flexible manned tail gunner's station.
• This type of mount has been a popular retrofit for altazimuth mounted telescopes, such as the common Dobsonian telescope type, adding equatorial tracking for high magnification work and astrophotography.
