Description

This dual axis motor drive, with drive corrector capabilities, is designed for Celestron's CG-4 mounts for tracking in RA and allows movement in DEC. They precisely control the telescope's tracking speed during long, timed exposures of celestial objects, producing the best possible image sharpness. Precision drive correctors are a must for those with a serious interest in astrophotography or CCD imaging. Four speeds are available -- 1x (sidereal), 2x for guiding, 4x, and 8x for centering.
This precision, state-of-the-art DC motor drive operates from 4 D-cell batteries (user supplied). The hand controller module is very compact and fits easily in the palm of your hand. Motors for both axes are included, along with brackets, clutches and hardware.
CHOKING HAZARD - small parts may pose a risk to children under 6 yrs.

    These motors were extremely easy to add to the mount and are very quiet. They move my 13.4 pound astrophotography setup and the two counterweights with no problem.
    I like that the hand controller light flashes when the batteries are getting low. I use rechargeable batteries and this makes sure I don't lose power in the middle of a session.
    The hand controller buttons work well and the cords are plenty long.
    Another review noted that there is a lag between pressing a button and the mount moving. That is caused by backlash in the mount. Close observation of the dec motor gears shows that they start turning immediately when the button is pushed.
    Yes, there are only 3 speeds and you can't slew the mount around the sky as previously noted but I have no problem getting the pointing close by using the clutches and hand adjusting the mount, then fine adjusting with the hand controller. Making small adjustments at 8x during astrophotography sessions works great.
    I've attached a picture (series of stacked pictures) of the Orion Nebula taken with the described setup and the motors were instrumental in getting there.

    Comments about Celestron Motor Drive Dual Axis Model (CG-4 Mount):

    Very good quality, and works well. It would be better if there was a release for both axis if a manual adjustment is needed. As it is now only one axis can be controlled manually if needed. Also the slew rate is a little slow.

    TRACKS LIKE A DREAM !

    Comments about Celestron Motor Drive Dual Axis Model (CG-4 Mount):

    My Cg4 mount is well balanced and carefully polar aligned.
    I installed the dec. and r.a motors easily.
    I used a wire loom to dress the cables and waited for dark skies. The scope at Vega tracked for one hour then rechecked at two hours found the star still centered in a 12mm eyepiece. Seamless product.

      Comments about Celestron Motor Drive Dual Axis Model (CG-4 Mount):

      I bought these drives for use with my Meade 6 inch F5 Schmidt Newtonian which I have mounted on the Celestron CG-4 mount. The instructions are clear and the installation is a breeze. The motor drives handle the 12 pound optical tube with no problems. Initially I was dissatisfied with the performance of the RA drive. With the motor running, high magnification views were blurred by vibration. With the drive off the image was steady and clear. Apparently this is fairly common with stepper motor drives that turn in tiny pulsing increments. The cause of this vibration is due to gear slop in the mount...not the drive motor. The cure is to adjust the gear mesh in the mount as tightly as possible without undue binding. The drive instructions explain how to adjust the CG-4 mount worm gears. but mention nothing about vibration being a possible result of improper adjustment. The troubleshooting section only talks about the adjustment being too tight and stalling the motors, or too loose and causing backlash. However,it is worm gear backlash in the mount adjustment that causes the RA motor to 'click" as the play between the gears is taken up and released by the pulsing on-off rotation of the drive motor. This clicking of the gears then induces vibration. The trick is to eliminate all play in the worm gears. This may require some trial and error to get right, but when dialed in properly the vibration is gone.
      The only complaint I have about this drive is that the RA motor has no de-clutching attachment as the Declination motor does. That means that the manual RA slow motion control cannot be used. Other than that small complaint the drive once dialed in works very well and tracks accurately.
