Manufacturer's product description: Motor drive suitable for the following telescopes : Omegon 150/750 EQ-3 Teleskop Omegon 76/900 EQ-2 Teleskop Zoomion Gravity 150 EQ Omegon EQ-3 motor drive - the motor drive for your Omegon EQ-3 telescope It is clear starry night. An object is in the field of view - perhaps the planet Jupiter - you note how the planet slowly moves in the field of view. You continually have to use the manual slow motion controls of your telescope to get the object back into the centre of the field of view. But this is also possible automatically Use the simple method of employing a tracking motor with your Omegon EQ3 mount. This will save you having to constantly adjust the telescope by hand. Once attached, you will then be able to concentrate much better on your observing. The motor relieves you of this irksome burden and will track your telescope in synchronisation with the movement of the stars from now on. The object you are observing will remain permanently in the field of view when the motor is operating! Even more features You also receive a handbox for controlling your telescope with the Omegon EQ-3 motor drive. Four large keys provide 8x and 2x tracking speeds and for temporarily stopping tracking. This means you can also follow objects at higher speeds and keep them positioned in the field of view. There is also an ON/OFF switch and a switch for selecting which hemisphere you are on. This means that the Omegon RA tracking motor can be used anywhere in the whole world. The handbox is ergonomically designed so that it is easy and safe to use even when wearing gloves. The advantages in a nutshell: RA axis motor for automatic tracking drives the main axis of the telescope well suited to visual observing comfortable to use: manual adjustment is no longer necessary straightforward assembly, only taking a few minutes handbox for 2X and 8X tracking speeds switch for northern and southern hemispheres It's a clear starry night.
