The equatorial mount allows one axis of the telescope to be parallel to the Earth's axis. This allows you to track an object by only changing one axis. This axis is Right Ascension. The other axis is Declination.
"EQ" on a telescope lens typically refers to the type of mount the telescope sits on. EQ stands for equatorial mount, which is a type of mount that can be aligned with the Earth's axis to track celestial objects as they move across the sky.
The two most common types of mount are the alt-azimuth mount, and the equatorial mount, the latter being tricky to set up at first, but much easier to use in the long run. There are other special purpose mounts, too, especially for observatory instruments.
At the Amundsen-Scott South Pole Research Station, supported by the United States of America, you'll find the South Pole Telescope (SPT), which is a 10 meter (394 in) diameter telescope. The telescope is an off-axis Gregorian type in an altazimuth mount -- effectively identical to an equatorial mount. The first camera mounted in the telescope is a 960-element bolometer array of superconducting transition edge sensors. It is one of the largest arrays ever built. The current camera also contains superconducting transition edge sensors and is more sensitive than the first camera and can measure the polarization of incoming light.
Mounts vary in complexity. A simple mount has the purpose of holding the telescope steady. Fancier mounts can have built in motor drives and even computers to find and track stars as they move across the sky.
"Optical", in this case, simply means that they work with light.

A German equatorial mount has the counterweight bar on the opposite side of the telescope, making it easier to balance. It also has a polar scope for precise alignment. A standard equatorial mount has the counterweight bar on the same side as the telescope and may not have a polar scope.
The Hale Telescope is a 200 inch (5.1m) reflecting telescope with a focal ratio of 3.3. It is mounted on a "horseshoe" equatorial mount.

My new telescope has an equatorial mounting. Opinionated articles in the newspapers of Ecuador could be described as equatorial editorials. The range of the Blue-footed Booby is not justequatorial.

all i know is 4.telescope,mount for telescope,45 foot dome,and a dividing engine.
The Hale Telescope at Mount Palomar has an aperture of 200 inches.
The Anglo-Australian Telescope (AAT) is a 3.9 m equatorially mounted telescope operated by the Anglo-Australian Observatory and situated at the Siding Spring Observatory, Australia at an altitude of a little over 1100 m. It is jointly funded by the United Kingdom and Australia,The AAT was one of the last large telescopes built with an equatorial mount. More recent large telescopes have instead adopted the more compact and mechanically stable altazimuth mount. The AAT was however one of the very first telescopes to be fully computer-controlled, and set new standards for pointing and tracking accuracy.

Since the motion of any object in the sky centers around the Celestial Poles, and the purpose of the telescope's sidereal drive is to cancel that motion so that the object being observed appears motionless, the sidereal drive's axis must point toward the Celestial Pole. In California, the one on which to align your equatorial mount is the North Celestial Pole, since that's the one that's visible from anywhere in the northern hemisphere.
It is a telescope on an equatorial drive (one axis parallel to the Earth's axis). An electric motor drives the other axis at 15 degrees per hour to follow an object as it moves across the sky.
