ZWO Counterweight Bar for AM3 / AM5

ZWO Counterweight Bar: balance for heavier setups

The AM3 and AM5 work up to 8 and 15 kg respectively without a counterweight, but towards those maximums, balancing pays off. You attach this stainless steel counterweight bar to the side of the mount, after which standard counterweights with a 20 mm bore slide onto it.

The result: less torsion on the axis, less load on the drive, and measurably smoother tracking. With a counterweight, the payload capacity of the AM3 increases to 13 kg and that of the AM5(N) to 20 kg.

Features

• Increases the load capacity: AM3 up to 13 kg, AM5(N) up to 20 kg
• Reduces torsion and improves tracking accuracy
• Stainless steel, direct side mounting to the mount
• Suitable for standard counterweights with a 20 mm bore

Compatibility

Exclusively for the ZWO AM3 and AM5(N) harmonic mounts. Recommended for long OTAs or heavy setups such as a filter wheel, guider, and electronic focuser.

Specifications

A small component that the harmonic mounts of ZWO whose best tracking provides under heavy load.
