It slides onto the mount's counterweight shaft and locks in place, and it is supplied singly — one weight per order — so a mount can be built up to whatever total the load on the saddle needs.\u003c\/p\u003e\n\n\u003ch3\u003e\u003cstrong\u003eWho It's For\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eAZ-EQ6 owners who have added mass to the saddle since the mount arrived: a larger tube, a heavier dovetail, a guide scope on top, or a camera, filter wheel and off-axis guider hanging off the back. When the shaft runs out of travel before the mount balances, another 11 lb of counterweight is what restores it. It is also the replacement part if a weight has been lost or damaged.\u003c\/p\u003e\n\n\u003ch3\u003e\u003cstrong\u003eKey Features \u0026amp; Design\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e11 lb of counterweight mass:\u003c\/strong\u003e the figure Sky-Watcher publishes for this weight. On a German equatorial the counterweight sits well out from the RA axis, so 11 lb placed at distance balances considerably more than 11 lb of telescope near the saddle.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt for the AZ-EQ6 shaft:\u003c\/strong\u003e Sky-Watcher lists this weight as working on AZ-EQ6 mounts, so the bore and the locking arrangement match that mount's shaft.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold individually:\u003c\/strong\u003e one weight per unit, which is how a mount gets tuned — weights are added or moved rather than swapped for a different size.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo moving parts:\u003c\/strong\u003e it slides on, it locks, and it stays put.

That is the statement they make, and it is the one we stand behind — we have not carried it across to the EQ6-R, the CQ350 or the EQ8 family, which have their own weights.\u003c\/p\u003e\n\u003cp\u003eSky-Watcher does not publish the bore diameter for this counterweight, and they do not publish a shaft diameter alongside it. Because the bore is the one dimension that decides whether a weight goes on a shaft at all, that is a gap worth closing before ordering rather than after. Send us your mount model and, if you can, a caliper reading across the counterweight shaft, and we will confirm the fit for you — or measure the shaft on a mount here and compare.\u003c\/p\u003e\n\u003cp\u003eThe weight fits over the shaft the mount already has; it does not include a shaft, a toe-saver or an extension bar.\u003c\/p\u003e\n\n\u003ch3\u003e\u003cstrong\u003eGood to Know Before You Order\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOne weight per unit:\u003c\/strong\u003e the price and the SKU cover a single 11 lb counterweight. A mount needing two takes two units.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore and shaft diameter are not published:\u003c\/strong\u003e Sky-Watcher states AZ-EQ6 compatibility and the 11 lb mass, and nothing about dimensions. Rather than quote a figure we cannot source, we will confirm the shaft fit with you directly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo published weight figures exist:\u003c\/strong\u003e the AZ-EQ6 counterweight is described by Sky-Watcher as 11 lb, while their own shipping record for the same item lists 12.0 lb (5443 g). The 11 lb figure is the counterweight's rated mass; the higher number reflects packing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft capacity is finite:\u003c\/strong\u003e a shaft holds only so many weights before running out of length. If two weights are already on the shaft and balance is still not reached, the fix is usually an extension bar rather than a third weight.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandling mass:\u003c\/strong\u003e 11 lb concentrated in a small disc is dense for its size, and it is loaded onto a shaft at chest height in the dark. Fitting the shaft's retaining bolt before the weights go on is what keeps a dropped weight off your foot.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003e\u003cstrong\u003eFrequently Asked Questions\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eIs it difficult to set up?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. It slides onto the counterweight shaft and the locking knob clamps it in position.
