The ZWO Off-Axis Guider is highly effective and efficient. A great choice for those looking to avoid weighing down their setup too much with the additional component.

The Prism is a relatively large 8 x 8 mm, and due to how the OAG is designed you may mount it to your telescope, and then mount both your main imaging camera and your guide camera to this same OAG.

This OAG is compatible with all ZWO ASI cameras, and a variety of telescope threading options can be adapted for or attached to with great flexibility. Once connected, you will find the bonds between this OAG and your telescope to be stiff and exceptionally stable, as firm and lasting as could be desired. This generally can also be applied to the connections to your cameras.

• Seamlessly connects with any ZWO camera.
• The ZWO ASI120MM Mini is a perfect guide camera choice for this OAG.
