User Guide:
1. Please calculate the correct required distance for the imaging train at first
for example: you need to connect 21mm extender to ASI071 to achieve 55mm back focus distance: 17.5mm + 21mm + 16.5mm = 55mm
2. Take off the guide prism part and attach the OAG body to the telescope
3. I insert the prismatic part into the body of the MPC
4. Mount the guide camera
5. Screw the T2 or M48 adapter onto the imaging camera depending on your media type.
6. Mount the camera on the MPC in the correct position and lock the 3 screws in place.
7. The final configuration
Note: Make sure the prism does not block the imaging area
Use the guide screw to adjust the focus of the guide camera.
You'd better do it during the day to make sure the imaging camera and guide camera can achieve focus at the same position.
