Questions & Answers

David G : Can I use this on an Orion Skyview Pro equatorial mount?mark a : Yes, I was successful using that motor drive on that mount. Worked great.WILLIAM R : Just looked online and I would say yes you can use motor drives. Mine are on a Cg-4 mount, they are slow moving but with good polar alignment they work good
Rick B : Can I power this unit with a remote battery & if so what voltage does it require ?JIM B : hI - THIS IS VERY VOLTAGE SENSITIVE AND IS DESIGNED ONLY FOR USE WITH THE BATTERY PACK SUPPLIED. IF U TRY TO OPERATE IT ANY OTHER WAY SUCH AS THE CELESTRON POWER TANK YOU WILL INSTANTLY FRY THE ELECTRONICS. IT'S 1990 TECHNOLOGY THAT BADLY NEEDS UPDATING. ODDLY ENOUGH THOUGH IT TRACKS VERY ACCURATELY.RANDOLPH B : The hand controller specifies 6V of DC power so if you are asking about a 12V field battery, I would say no. I use the battery pack and 4 "D" batteries that last many, many hours. I've been very pleased with this product for visual astronomy tracking.
Eric O : can this dual axis motor drive be used on a celestron omni xlt 102mm refractor?M S : Yes it can. I use mine primarily to hold my camera and telephoto lens for star tracking. I have used it with a 150mm f/8 refractor.z it was very carefully balanced prior to turning on.CRAIG C : I'm using it with a XLT 150 refractor so I'd think the 102 shouldn't be an issue..RONALD F : I believe it will work since the omni xlt mount is the cg4, ie About the Celestron MD-4 as said below This dual axis motor drive, with drive corrector capabilities, is designed for Celestron's CG-4 mount. It precisely controls 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. These precision, state-of-the-art DC motor drives operate from 4 D-cell batteries (not included). 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.DAN S : I use this drive system on a Celestron CG-4 mount that it was designed for, and it works fine. If your Celestron telescope is not on a CG-4 mount per your owners manual, then it is best to contact Celestron. I Don't own an Omni xlt telescope, so I can't answer this question.MICHAEL D : Eric , Its been awhile but I know I put this set on a new style cg4. No problem as I recall.

Does The Job

The motors work well, most of the time. Although at times they will act non responsive when attempting to make small Dec adjustments, and then they'll "take off". Some reviewers have complained about the speed being too slow when making corrections, but they're listed as having an 8X top speed, so don't expect any more than that. They do track quite well if you're properly polar aligned. The biggest complaint I have is the flimsy looking battery pack and cheap wiring. It wouldn't take much to pull the wires loose, so make sure the battery pack is mounted solidly on something. I used velcro strips on one of the tripod legs to fasten it down. As for the battery life. Celestron claims 20 hrs on a set of four D cells. I've put about that much on mine so far and the batteries haven't died. All in all I think these motors are worth the additional cost. I've been able to track planets and keep them perfectly centered and taken long exposure photos of star clusters without trailing.

Great Kit, However, Use Instructions are Lacking.

Great product, however, it could use some more in-depth instructions. The install instructions are great, however, being novices in astrophotography, there is no resource for how to effectively use this kit well. Other than that, it is a great setup!

CG -4 motor drives

Controller malfunction, Dec control only works on 2x and 4x no 8x stays at 4. RA is fine works as it should, luckily I had extra controller that I acquired awhile back. Product should be tested before being shipped as is definitely a wiring problem in controller, hence the 1 star rating.

Celestron Dual Axis Drive for CG4

Will not work even after troubleshooting. User manual worthless. Changed batteries checked voltage and ran heavier cables to the controller. Motors buzzed but would not turn. Many others on Cloudy Nites had similar problems. Why hasn't Celestron fixed this glitch when it's so common and the product has been around so long???

Accurately tracks, electronics exposed

Tracking is surprisingly good with very low battery drain (don't use rechargeable batteries though - they don't supply enough voltage). However the circuit boards are exposed to the elements and can be easily damaged or broken off even with careful use. The battery holder is especially cheap in construction with very fragile soldering connections. Despite the accurate tracking, this unit is very overpriced due to poor construction.

Excellent CG-4 tracking

Does what it's supposed to, and has a clutch release for DEC adjustments via knob. However, doesn't allow for using RA knob to do any adjustments (requires use of controller).

Works like a charm.

These motors are the best investment I made for my new Omni XLT 150. They make your viewing sessions so pleasing. When sharing the night with others such as friends and family these motors are priceless. Allows me to even use 4m with a 2x barlow (highest magnification I have) and still stays right on taget while everyone takes a peak. Not to mention when viewing at this magnification and trying to use the manual knobs you get some vibration and shakiness. I highly recommened this to anyone buying a cg-4 mount.
