Celestron 93514 AstroMaster/PowerSeeker Motor Drive, Black

It saves time as you don’t have to use both hands together.

A bit noisier than I expected, but does its job and was easy enough to set up. Just one thing: My telescope is a Celestron 130EQ with a CG-3 mount, and I had to flip the switch to S, even though I'm in the northern hemisphere. Also, make sure that your telescope is balanced and that the screws are not too loose.

Does what it's intended to do. If you have a equatorial mount, in alignment with Polaris, it'll keep whatever you're looking at in the view, counteracting the spin of the Earth.It comes with brackets for a Celestron CG-2 or CG-3 equatorial mount and hooks onto the opposite side of the R.A. slow motion control (you can disconnect the manual control if you want, because this device ties the manual control to the motor so you can't turn it, but I find that on a CG-2 mount, just unscrewing the connector is enough to give you back manual control without having to remove the motor entirely from the telescope).It can sometimes get in the way when moving your telescope around the sky (e.g. to look at stars in the South while in the Northern hemisphere), but on those mounts quite a lot of things get in the way anyway. It only takes a minute to disconnect it and reconnect it if you really need to.It does whir, but it's not very loud - enough to let you know it's working.Otherwise, seems to do exactly what it's supposed to.

First of all, this product will only be worthwhile if you know how to set up your telescope's mount in alignment with polaris (or the celestial south pole), AND you can reliably find the objects in the sky you are looking for.the good points:-The Celestron 93514 Astromaster Motor Drive comes with a 9v battery and I found that it attaches to the telescope's R.A Slow motion control fairly easily and reliably.-Once you are aligned with polaris and you are pointed at the object you want to look at, the motor very slowly turns the R.A to counter the rotation of Earth, keeping the object in the eyepiece.-It is VERY useful when using high magnification eyepieces as planets, stars and nebulae tend to fly out of the field of view of the eyepiece rather quickly!The bad points:-There is a manual variable speed dial that you will have to set to the correct speed depending on the declination you are at. this fairly easy to judge correctly, although sometimes it takes a bit of trial and error, moving it both ways a few times before being able to keep the object you are looking at perfectly in the middle of the field of view.-Once it is attached, you will lose the ability to turn the R.A slow motion by hand, instead relying on using the motor to bring objects into view(which can take a while if they are quite far out of view).-The Celestron 93514 Astromaster Motor Drive IS NOT an automatic finder! It will not find the objects for you, it only helps to track them once you have found them.Overall I have found it very useful for taking long exposure photographs, and viewing planets for extended periods with high power eyepieces. The bad points are fairly easy to get used to and work around.One more thing to mention, when up and running it does emit a slight whirring sound, although it is not particularly loud and will only bother the most noise sensitive of neighbours at night.

Easily fitted to my Cellestron telescope. Works well. Thought it didn't work at first but the whole reason of this item is to track the movement of planets. Forgot that the movement is so slow. Once I realised this I found it very accurate in following planets. I am more than happy with the purchase.

Good little motor drive for telescope at a very reasonable price.

Does the job. Can be a bit tricky trying to adjust the speed to keep the object in view.

Bought 127eq as gift. Got this to keep the Moon in sight. Supplied battery nearly flat - probably been in storage for some time given it was sealed. Replaced with new, branded one. Unfortunately, worked for a few minutes, then the motor stopped. Wouldn’t work again. Checked the battery - no issue there.It’s a fairly cheaply-made unit, with a motor that really is at least a little underpowered. Certainly - for my scope - wouldn’t be able to handle a phone or camera attached to the scope. If you’re inclined, rather than spend £50 or so on this, perhaps make your own. Search online for “My low-cost DIY RA drive for EQ5 mount”. Not my own tutorial, but I’ve been following it and, for a few more pounds, you could make something more robust. Tip for those doing this: perhaps look for a simple DC motor with gearbox, rather than a stepper - probably cheaper and will still do a good enough job. Steppers can also be a little noisy in use, depending on your setup.Good luck!

El motor es de mucha ayuda a la hora de hacer astrografía, es sencillo de usar y elimina las molestas vibraciones de la cámara.

This clock drive was not made for my telescope but with just a little modification I was able to get it to work without too much difficulty. It seems accurate enough for my needs. My telescope is a cheap very old 60mm refractor with an old equatorial mount. Not worth a big investment but this clock drive was inexpensive enough that I thought I'd give it a try and it works fine.

Alles sehr gut

The product was delivered and shipped in good quality by TigrisDeals. I installed it on my Orion Starblast 4.5 EQ mount telescope. I had to use the eq2 mount adapter clamp provided. It works fine and you can comfortably track objects for your viewing sessions. Even the battery supplied was sealed and in good condition. Thanks Amazon for shipping this product in time.

The motor is a little noisy; however, this is easily muffled by putting a back between the case and the mounting bracket. The overall design is compact, thoughtful and clean. On a homemade dobsonian platform it will allow you to track the star and can save you hundreds and thousands of dollars over commercial units.
