CGEM mount noise
Posted 01 July 2009 - 07:14 AM
I'm thinking of getting my hands on a CGEM mount and was wondering just how loud these mounts are? I have a CG5 at the moment and after about 11pm I don't use the high speed slew rates anymore because they're just too loud and I'm pretty sure my neighbors don't appreciate that
So is the CGEM a big improvement quiet wise or not?
BTW, I'm already assuming that the CGEM is a serious upgrade from the CG5 in every other respect.

The CGEM is a sturdy mount and I've had good success in getting nicely autoguided images with a Meade 8" Schmidt-Newtonian.

I like my CGEM a lot, I wish it was quieter, but it isn't. The good news is that when tracking it is very quiet indeed. Is there a slower slew rate command for the CGEM? If so, I will switch to it and be happy.

CG standing for coffee grinder, that makes a lot of sense Certainly how I would describe it and only mildly less annoying then the LXD-75 which I also own. But that was my first decent scope so I'm a lot more forgiving of its shortcomings for no rational reason

What kind of problems? I've heard of a few teething problems with them.

I have a problem with the power cord that came with the mount. I was getting no responce 17 error codes. Come to find out the plug on the cord is very loose when you put it in the mount. I tried spreading the prong inside the plug on the mount but that didn't help. So now I use the cord from my cg5. Tha has seemed to fix the problem.
I don't think the CGEM has a quite mode for slewing. However, I don't think it's too noisy. It is much quiter than my cg5 when slewing.

No one has mentioned a "quiet slew" mode to the CGEM and I can't find one in the manual, so I am going to assume that this feature does not exist.
That's right. Celestron did not implement the quiet mode. I believe it is an Autostar's feature only. You could get close to a quiet mode with the CGEM when you run it off a battery.

Blixx, saying that a CGEM is quieter than a CG5 or LXD 75 is like saying that a women is better looking than Rosanne Barr...not much of a standard.
Mich Al, I am not asking about the slew speed as selected for manual slew, this is about the slew rate automatically chosen by the electronics when you hit the "Enter" button to go to a chosen object.
Well, now that I know that there is no "slow slew" command on the CGEM, I will just keep it greased and get the gears adjusted and live with it.

I should add that the CGEM is not so noisey that it wakes my neighbors. I use it in the backyard late at night with no real problems. The LX200 on the other hand actually did wake the neighbors unless I set its goto speed much slower.

...and â‚¬500 cheaper then the CGEM too!!

Is this the only place it is lacking, its goto abilities or are there other major omissions?

The only other improvements to the CGEM were the new motors (which are also louder), the counterweight bar's increased size, and the CGE style saddle plate.
The old motors worked fine, the old counterweight bar was fine but could also be replaced easily, and I replaced the saddle plate with a dual plate from ADM anyway. So no real earth shattering differences. But you will probably want to replace the saddle plate on your HEQ6 as I did on my CGEM. That ADM dual plate is really sweet.

Would like the CGEM still but it's another 500. Not sure I want to spend that much more. In terms of the CGEM slewing noise, at its loudest is it as bad as the CG5 or are we talking a lot quieter then that?

I can't say much about the CG5 because no one that comes to our dark site owns one. But from what I read on cloudy nights I am guessing the CG5 is almost as noisey as the LX200 and the LX200 can wake the dead.
