Why Are Telescope Mounts Necessary?
A telescope mount is the basic structure that is able to hold or support a telescope during use or during stand-by. Aside from supporting the weight of a telescope, a telescope mount also allows for accurate movement and aiming of the telescopic instrument to the area that you are observing. Without telescope mounts, you would be required to manually carry and move the telescope around while doing your observations, which would be burdensome especially if you have a telescope that is more than five kilograms in weight.
What are the two general types of telescope mounts? The first type of telescope mount, which is also used by amateur telescope making communities, is called the Altitude-azimuth mount (which also goes by the names of Altazimuth or alt-azimuth). The Altitude-azimuth mount allows your refracting or reflecting telescope to move about, utilizing perpendicular axes. The movement allowed using the perpendicular axes can be vertical or horizontal. Why the choice for the name of Altazimuth? Well, people call the upward movement of the telescope on an Altazimuth telescope mount the “altitude” and the movement that is characterized as horizontal is called the “azimuth” movement of the telescope on the mount. What are the benefits of the Altazimuth telescope mount? First and foremost, it’s easy to make, and cheap to maintain too. Without such a mount, your telescope would be lying around in your room or on your lawn, and the elements would probably get to it first. And you wouldn’t be able to make accurate aims if you don’t have a mount.
Another type of telescopic mount is the equatorial mount. The equatorial mount has the name because, it has an axis that is able to rotate, much like the same way the Earth rotates on its own axis. Telescopes that have equatorial mounts are often equipped with small motor devices that enable the user of the telescope to track the distant objects in the sky. How are these features helpful for the aspiring astronomer? Well another feature allows your telescope to rotate on command; one may program the circling of the axis in line with coordinates in the sky. And so, if you are capable of utilizing such features, then tracking celestial objects such as stars and planets would not be difficult, since the telescope would be doing most of the moving, while you simply do your celestial stargazing.
Motorized tracking is great; but wouldn’t you know, telescope mount manufacturers have increasingly made much more significant improvements on telescope mounts, integrating object location and motorized movement to such a degree that there is a possibility that you may just set coordinates and let a hand-held computer do the rest of the work. For aspiring scientists with the right stuff, a telescope mount is vital. Other types of mounts include the German mount, the English mount, the English Fork and the Open Fork. All in all, stargazing is made possible by mounts because it assures a steady movement for your careful observations.
