When should I use the iOptron 2kg counterweight instead of a standard one?
The iOptron 2kg counterweight is ideal for balancing very light payloads, such as a small wide-field refractor or a DSLR with a telephoto lens. Standard 5kg+ weights can be too heavy for these setups, making it difficult to achieve precise balance. This 4.5 lbs. weight gives you the fine control needed for optimal mount function.
Will this 2kg iOptron counterweight fit a non-iOptron mount?
This counterweight is designed for a 20mm diameter shaft, as confirmed by its 20.5mm inner bore. While it may fit other brands of mounts that use a 20mm shaft, compatibility is only guaranteed with the iOptron CEM26, GEM28, and AZ Mount Pro.
How many iOptron 2kg counterweights do I need for my William Optics RedCat 51 on a GEM28 mount?
For a lightweight setup like a RedCat 51 (which weighs around 1.5kg) on a GEM28, a single iOptron 2kg counterweight is typically sufficient to achieve proper balance, depending on your camera and accessories. It provides the right amount of mass without being excessive for such a portable rig.
Can I stack the iOptron 2kg counterweight with other iOptron weights?
Yes. You can use the 2kg counterweight in combination with other iOptron weights on the same 20mm shaft. This is a common practice for precisely balancing a payload that falls between the standard weight increments.
What is the benefit of the 'locking screw with pin' on the iOptron 2kg counterweight?
The locking screw with an integrated pin provides a more secure hold than a simple thumbscrew. The pin engages with the shaft to prevent any slipping or rotation, while the screw provides the clamping force. This design also helps prevent damage or deep scratches to the surface of your counterweight shaft.
I'm imaging with a DSLR and a 200mm lens on my CEM26. Is the iOptron 2kg counterweight the right choice?
Absolutely. A DSLR and lens combination is a perfect use case for the iOptron 2kg counterweight. This payload is too light for a standard counterweight, and the 2kg (4.5 lbs.) weight will allow you to perfectly balance the load on your CEM26 for stable, accurate tracking.
