Why would I need a counterweight for the HAZ46 mount?
Strain wave gear mounts like the iOptron HAZ46 operate without counterweights for many payloads. However, for optical tubes that are particularly heavy or have a long moment arm (like a large refractor), adding a counterweight improves stability, reduces load on the drive motors, and can lead to more accurate tracking for long-exposure astrophotography.
Is the HAZ46 Counterweight Shaft necessary for imaging with my 8" SCT?
It depends on your imaging train. An 8" SCT by itself may not require it, but if you add a heavy cooled camera, filter wheel, and off-axis guider, the total weight and its distribution can create an imbalance. The HAZ46 Counterweight Shaft allows you to perfectly balance this heavier configuration for optimal tracking.
Will adding the HAZ46 Counterweight Shaft make my setup less portable?
Yes, adding the shaft and one or more counterweights will increase the total weight of your setup. This is a direct trade-off for achieving better balance and stability with larger telescopes. The shaft itself is lightweight and can be easily removed for transport, but the counterweights themselves add significant mass.
What counterweights fit the HAZ46 Counterweight Shaft?
This shaft is designed to be compatible with standard iOptron counterweights. Please refer to your mount's documentation to ensure you select a counterweight with the correct bore diameter for the shaft.
I'm imaging with a 120mm f/7 refractor on my HAZ46. Would this help?
Absolutely. A 120mm refractor, especially with a dew shield and a full imaging rig, creates a long moment arm. The HAZ46 Counterweight Shaft & Adapter is highly recommended in this scenario to provide a stable, balanced platform, which is critical for achieving sharp, round stars during long exposures.
Does the HAZ46 Counterweight Shaft & Adapter include the actual counterweights?
No. This product includes only the counterweight shaft and the adapter needed to attach it to the HAZ46 mount. Counterweights must be purchased separately based on the needs of your specific telescope payload.
