The ZWO off-axis guider allows photography and guiding with the same telescope.
Usage Guide
1. Please calculate the correct required distance for your imaging train at first
for example you need to attach 21mm extender to ASI071 to reach a 55mm back focus distance:17.5mm+21mm+16.5mm=55mm
2. Take off the guider prism part and attach the OAG body to the telescope.
3. Insert the prism part into the OAG body
4. Mount the guide camera
5. Screw the T2 or M48 adapter on the imaging camera according to your mount type.
6. Mount the camera on the OAG in the correct position and lock the 3 screws in place.
7. The final setup
Note: please make sure the prism won’t block the imaging area.
Use the guiding screw to adjust the guiding camera’s focus.
You’d better do it in the daytime to make sure the imaging camera and the guiding camera can reach focus at the same position.
