Please note, ZWO have re-designed their OAG earlier in 2018. We've now updated the product description and images to reflect these changes.
What's in the box (see above image):
How to use it:
1. start with caculating the correct required distance for your imaging train.
for example: you need to attach 21mm extender to ASI071 to reach 55mm back focus distance:17.5mm+21mm+16.5mm=55mm
2. Take off the guider prism part and attach 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 the mount type
6. Mount the camera on the OAG in correct position and lock the 3 thumb screws
7. Setup is complete
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 to do it during the day to make sure that the imaging camera and guiding camera can reach focus at the same position.
