ZWO Non-rotating Helical SCT Microfocuser for all SCTs
A premium upgrade designed for astrophotographers and observers who require micro-fine focus control. This ZWO 1.25" Helical Focuser allows very fine focus of a guide camera for astrophotography. Made of anodized machined aluminum, the focuser fits on a ZWO off-axis guider and accepts a mini guide camera in its top end. With a focusing stroke of 6mm and adjustment accuracy of just 0.1mm, the focuser assures the guide camera has a perfect view of the object you're tracking. The focuser has a female M42 x 0.75 thread for attaching to the OAG and a brass locking nut to hold the mini camera securely in place, as well as a male M42 x 0.75 on the top end for using the focuser in other situations.
For use with ZWO OAG (Off-Axis Guider) and ASI Mini Series cameras. Can also be used for other applications when focusing is required.
