Use of this kit if the camera and lens together weigh between 2.6-pounds and the mount's max payload capacity of 6.6-pounds, or if the lens is long. The kit includes the mounting plate and hardware, plus a counterweight shaft and a 3-pound (1.35kg) weight.

Documentation could be better

The counter weight itself is fine. The documentation / illustration on the iOptron website could be better. In one picture they show the threaded stud for the camera mount as coming through the flat side rather than the end of the plate. Also, tips on how to balance the counter / camera would be helpful.
iOptron Skytracker Pro Counterweight

The counterweight kit contains high-quality components. However, it lacks any instructions on how to assemble and use the counterweight. You can find information regarding the use of the counterweight online easily.

Is this compatible with the Ioptron Skyguider ...
Is this compatible with the Ioptron Skyguider Pro? I'd like the option of adding the shaft and/or counterweight onto the SGP that I currently have.
Yes this set up is compatible.

question
I own this conterweight kit. The actual 3 pound weight is too heavy for my setup. Is there any other lighter weight I can use with my kit?
One can use the iOptron 2.2 lb. Counterweight for SmartEQ Mounts,(available from "High Point Scientific"), it is the lightest counterweight iOptron offers at this point.

question
Does using this counterweight lower the 6.6-pound payload limit of the SkyTracker Pro?
I concur with Joe's response; I just spoke to Yuen in tech support at iOptron (Phone : 781-569-0200), and he assured me that the 3kg payload is independant of the 1.35kg counter weight. So do not subtract weight of the CW set from the payload capacity.The total weight of the camera, lens, ball-mount/head, and CW set should not exceed 4.35kg (3kg payload capacity + 1.35kg CW set).

question
Will this counterweight kit work with a vixen polarie?
Maybe. Tricky. When used with the iOptron, the counterweight kit requires that one remove the circular turntable to screw the dovetail plate onto the tracker. The Polarie plate appears to be similarly removable, so I would guess that this will work.The iOptron counterweight kit comes with the screw adapter that converts from 3/8 x 16 to 1/4 x 20. Clearances would be critical, but again, I feel this will work. Can you buy it with an option to return? Best of luck.
