Hi Geoff.
I can't see the manual you attached so can only go on an Orion video. There might be multiple models made over the years, not sure if it matches your OTA version.
Can you confirm please:
1. Is this 200mm/1600mm f8?
2. Is your focuser rotatable?
3. Does the 2" segment of the focuser have M48 threads to attach camera etc, or only the compression ring?
4. The photos don't show 2nd dovetail / rear radius block or screws. Are they included but not pictured?
Cheers
Rob
