iOptron HEM27 counterweight shaft: counterweight shaft for the HEM27
This 200 mm counterweight bar screws directly into the HEM27 with its M16 thread. The hybrid strain wave mount can also carry loads without a counterweight, but with a bar and weight, you relieve strain on the drive mechanism and improve tracking stability for heavier imaging setups.
The 20 mm diameter fits the standard iOptron counterweights; the length provides room for multiple counterweights.

Robust and directly matching
The rod is made of solid material and is firmly fixed without play after being screwed in. This keeps the setup stable, even with multiple kilograms of weights.
Included
- Counterweight rod 200 mm with M16 thread
Featured accessories
Combine the bar with the 1.35 kg counterweight with a 20 mm bore as the starting weight.
For whom yes and for whom no
- ✓ HEM27 owners who want to improve tracking accuracy with a heavier camera setup
- ✗ Other mountings: check the M16 thread and rod length first
