Celestron AstroMaster/PowerSeeker Motor Drive

This motor drive is designed exclusively for Celestron telescopes that use a CG-2 or CG-3 equatorial mount. This includes most models in the AstroMaster and PowerSeeker series. It is not compatible with alt-azimuth (AZ) mounts or other manufacturers' equatorial mounts.

When observing a planet like Jupiter at high magnification with a PowerSeeker 127EQ, it will drift out of the eyepiece in under a minute. The motor drive corrects for this by tracking Jupiter's movement, keeping it centered. You can use the speed regulator to precisely match Jupiter's specific rate of motion across the sky, allowing for much longer, more detailed views of its cloud bands and moons.

Yes. Proper polar alignment is essential for the motor drive to work correctly. The drive only moves the telescope in Right Ascension. If the mount is not accurately aligned with the celestial pole, the object will still drift out of the eyepiece in declination.

This drive is excellent for keeping objects in the field for visual observation and can enable short-exposure planetary or lunar imaging with a webcam-style camera. However, for long-exposure deep-sky astrophotography, a more robust mount with dual-axis drives and autoguiding capabilities is recommended for higher precision.

Battery life can vary based on temperature and the quality of the battery used. A fresh, high-quality 9V alkaline battery will typically provide several nights of observing. It's always a good practice to carry a spare battery with you.

The Moon moves at a different rate than distant stars. To adjust, simply turn the "Speed Rate Regulator" knob located on the motor drive. You can slightly speed up or slow down the motor until the Moon remains centered in your eyepiece without drifting.
