The counterweight matches the original. It is well made and fits perfectly.

Will also fit Meade lxd75 mount

Purchased as a smaller weight when using small scope and DSLR on a Meade LXD75. Weights smaller than 10-11 pounds are hard to find with the required 19-20mm shaft diameter for these old mounts. Can also use this weight when I replace the LXD75 with an Ioptron strain wave mount as my portable mount.

Will I need this additional counterweight to balance a 5.2lb setup on the Skyguider Pro? The tracker already comes with one, but I'm not sure if it will be enough to balance the mount.
Asked by: Pera
It will depend on the items you are mounting.

From the photo, it looks like there is a "step" inside the counter weight hole. Is the .8" diameter measurement the wider part or the narrower part of the hole?
Asked by: John
The image is the same image that is on the iOptron website. There is no step.
