ZWO helical focuser travel

Recommended Posts

I recently bought the ZWO OAG and also a ZWO Helical Focuser. I tried them out last night, but had trouble adjusting the helical focuser’s outward travel. I removed it from the OAG and it was smooth as silk, movement both in and out to maximum travel.

However when added back onto the OAG the same issue repeats. Basically you can move the travel inward towards the OAG, but it seems to stick on the way out. This causes issues if you over correct, because you have to remove the helical focuser & camera to reset it. Does anyone have the same issue?
