UForkMount. A gun turret is essentially an alt-azimuth mount for a gun, and a standard camera tripod is an alt-azimuth mount as well. Attaches to an iEQ45 tripod or pier. Typical current applications of altazimuth mounts include the following.

Another limitation is the problem of gimbal lock at zenith pointing. The entire building constitutes the altazimuth mount, saving on mass and cost. Astronomical telescope altazimuth mounts. On the other hand, an equatorial mount only needs to be rotated about a single axis, at a constant rate, to follow the rotation of the night sky (diurnal motion). View cart for details. The pointing direction of the mirror is perpendicular to its surface. $275.00. The primary disadvantage is its inability to follow astronomical objects in the night sky as the Earth spins on its axis.

[5] The simple structure of an altazimuth mount allows significant cost reductions, in spite of the additional cost associated with the more complex tracking and image-orienting mechanisms. 0 bids. Made in Germany. 365Astronomy Giant Alt-Azimuth Telescope Mount Head ONLY This mount provides heavy-duty Alt-Azimuth telescope carrying capabilities up to about 12kg payload. Beginner telescopes: Altazimuth mounts are cheap and simple to use. When used as an astronomical telescope mount, the biggest advantage of an alt-azimuth mount is the simplicity of its mechanical design.The primary disadvantage is its inability to follow astronomical objects in the night sky as the Earth spins on its axis. This imparts an uneven rotation to the field of view that also has to be corrected via a microprocessor based counter rotation system. The tripod has a load capacity of 15lbs and is perfect for small to medium sized telescopes up to 6" aperture. This iOptron AZ Base converts the iEQ45 from an equatorial mount to an alt-azimuth mount.

A heliostat at the THÉMIS experimental station in France. Filters Sort by . female 3/8" photo thread to connect to a tripod with large binoculars. Thus, altazimuth telescopes, although they can point in any direction, cannot track smoothly within a "zenith blind spot", commonly 0.5[3] or 0.75 degrees[4] from the zenith. When tracking at elevations close to 90°, the azimuth axis must rotate very quickly; if the altitude is exactly 90°, the speed is infinite. The latest technology also enables precise tracking in both Several names are given to this kind of mount, including altitude-azimuth, azimuth-elevation and various abbreviations thereof. AZT6mount. An altazimuth or alt-azimuth mount is a simple two-axis mount for supporting and rotating an instrument about two perpendicular axes – one vertical and the other horizontal. Ending Nov 25 at 7:08AM PST 4d 23h. The design also does not allow for the use of mechanical setting circles to locate astronomical objects although modern digital setting circles have removed this shortcoming. Celestron NexStar 5 SE Computerized GoTo Mount Head - Also 4SE - Head Only – NEW. Compatible with later versions of the iEQ45 that do not come with an 8406 hand controller. [6] An altazimuth mount also reduces the cost in the dome structure covering the telescope since the simplified motion of the telescope means the structure can be more compact.[7]. at elevations greater than 89.5° or 89.25° respectively.). A great grab-and-go tripod. Therefore, you can attach something like binoculars or a spotting scope on one side and a powerful telephoto lens on the other. Altazimuth mounts need to be rotated about both axes at variable rates, achieved via microprocessor based two-axis drive systems, to track equatorial motion. Rotation about the vertical axis varies the azimuth (compass bearing) of the pointing direction of the instrument. In the largest telescopes, the mass and cost of an equatorial mount is prohibitive and they have been superseded by computer-controlled altazimuth mounts. The mirror rotates on an alt-azimuth mount. The advantage of this design is that there is no need for a counterweight as a second optical system can be used as a counterweight when attaching comparatively heavy telescope tubes. [1] On smaller telescopes an equatorial platform[2] is sometimes used to add a third "polar axis" to overcome these problems, providing an hour or more of motion in the direction of right ascension to allow for astronomical tracking. These mounts are used, for example, with telescopes, cameras, radio antennas, heliostat mirrors, solar panels, and guns and similar weapons. (i.e. Rotation about the horizontal axis varies the altitude (angle of elevation) of the pointing direction. The Orion VersaGo II Altazimuth Mount is very stable yet light weight and portable at an affordable price. $39.50 ... 0 bids. instead 257,76 EUR only 180,17 EUR* * excl.Shipping costs.
