R.A. Tracking Motor System for Bresser Messier R102, R127, R52, N150 & N203. With this motor you can track celestial objects automatically by using right ascension without the need to manually correct the telescope. Increases the pleasure of observing and also allows astrophotography with your Bresser Messier R102, R127, R52, N150 & N203 telescope. Comes with hand controller and rechargeable battery (batteries not included but can be ordered on our site).
Why use a tracking motor?
Any observations you make will take place from the earth. This means that when looking through the telescope at a celestial object, the object slowly moves out of the field of view, if you don't move the telescope. Because of the earth's rotation, you must compensate this rotation by continuously adjusting the telescope so that the object is kept on screen.
You have to adjust your telescope both horizontally and vertically. You can do this automatically using a tracking motor. A tracking motor is available in two versions, one that only compensates for the horizontal axis (or right ascension) and one that compensates both the horizontal and the vertical axis (declination).
The above engine compensates both the right ascension and declination.
If you want to take pictures of objects the object ramains absolutely stationary relative to the camera and this is a big plus. If you would try this by hand, your photos would quickly look faded.
