ZWO Helical focuser

Solid unit, helped with focusing in the guide camera. Probably a bit of an overkill for what I use it, since you set and forget, but quite happy with it.

ZWO Helical focuser

The unit is well made. It is almost impossible to obtain focus with out when using the ZWO OAG. It is a must when using this tracking option the distance to the camera is so sensitive without the helical focuser
