Until recently I was using an 11lb counterweight that came with my CG-5 and a 7lb weight from my CG-4 to balance my AR152. With this configuration the weights were pretty much at the end of the counterweight bar. I finally ordered an extra 11lb counterweight just like the one that came with the mount so that I could put the 7lb weight back on the CG-4 and leave it. However, since going to the new configuration, with 2 11lb counterweights, I've noticed that the mount seems to be less stable and shakes more when focusing. Are the counterweights counted as part of the mounts overall capacity?

Mike,

I'm not sure what the weight of the AR152 is, but I have an AT152 which is around 24 to 25 pounds excluding the diagonal and eyepiece. I use the 2 11 pound counterweights to balance it on my CG-5 and have never experienced the vibrations or imbalance you are having.

As far as I know the CW's are not counted towards to mounts overall capacity. With the AT152 on the mount the weights are about one and a half inches from the end of the CW bar.

I assume you have checked everything on the mount to insure things are tight.

Hans,

The AR152 weighs about 25 pounds with all accessories and a 2" EP. The scope balances just fine. It just seems like there's more shake when focusing since I added the second counterweight. I also recently moved the tripod alignment peg so that it sits over a tripod leg instead of between two legs. Not sure if moving the alignment peg would have any affect on stability or not.

I didn't think the counterweight's should count toward the mount's payload capacity, but wasn't sure.

I might just go back to my original configuration and see if that helps. I can use the new 11lb weight on the CG-4.

I actually haven't checked this. Is there anything specific I should check?

First thing I would check is that the knob to tighten tripod to the mount (underneath the eyepice tray spreader)is secure and tight.

Yep, that would be a good one to check. :)

Thanks!
