How do I track Celestial Objects with an Equatorial Mount?
When you observe a celestial object through the telescope, you’ll see it drift slowly across the field of view. To keep it in the field, if your equatorial mount is polar-aligned, just turn the R.A. slow-motion control. The Dec. slow-motion control is not needed for tracking, but may be required to center the object. Objects will appear to move faster at higher magnifications, because the field of view is narrower. A DC motor drive system can be mounted on all Orion equatorial mounts to provide hands-free tracking. Motor drive systems are typically offered as an optional accessory. Objects will then remain stationary in the field of view without any manual adjustment of the R.A. slow-motion control. A dual-axis motor drive is necessary for astrophotography.
