    Default Power usage of Celestron dual-axis drive motors for CG-4 Mount?



    Hey Fellow Stargazers!

    I have just ordered the Celestron #93522 Dual-Axis Motor Drive add-on for my new Omni XLT120 on a CG-4 mount. I see it uses a (4) D-Cell battery pack to power the motors.

    I anticipate using the 'scope on my deck a lot more often than at 'remote locations', and I don't like buying tons of batteries. So I would like to know how much current will be drawn by the RA drive motor. [The Dec-motor will be used either not at all or for very short periods while an object is centered in the eyepiece, so if I add a 25% 'overhead' factor to the RA-motor power required it should be enough to handle both the RA- and Declination-drive motors].

    I would like to find a "wall-wart" type 6V power supply to use instead of the (4-battery) D-cell battery pack. I have found a source for a 6V @ .4A power supply for around $5.00; I could easily spend $5.00 on a single set of D-cells that might only last me for one or two observing sessions.

    I already have a number of 'wall-warts' in various output voltages that I have collected over the years, so I may already have the one I need, but without knowing the power requirement, I can't really tell without obtaining more information.

    Does anyone have the specifications for the motor drive including the power consumption?

    Failing that, has anyone been using the 4xD-Cell battery pack with the motor-drive package who can tell me about how long a set of batteries will last before pooping out? [I would need to know what kind of D-cells you use too, whether Alkaline, NiMH, Carbon-Zinc, or whatever so I can get an idea of the power draw]

    My new drive-kit is arriving this Friday... I'll probably buy a set of D-cells and may be able to answer my own question by Saturday morning, but I'd like to know ahead of time whether what I already have will fit the bill.

    Any feedback will be appreciated.

    Hi Glider, I don't know if you've answered your question yet, but I've got the exact same setup and those drive motors work like a champ with the battery pack. I don't really use it an awful lot, because I usually swing the scope manually over long distances and just use the motors to keep the target centered in the eyepiece, no more fumbling around in the dark for the fine tuning knobs. Just using it like that makes observing much more pleasant and efficient, and my duracells have lasted about 6 months so far.
