Roland,

Following up on the flat surface adapters, I see three options

1. 119FSA - > https://www.astro-physics.com/119fsa
2.119FP  https://www.astro-physics.com/119fp
3. 119FSA-FP https://www.astro-physics.com/119fsa-fp

If I want an option to use my Paramount MX 10 inch permanent pier to mount the AP1100 or a Mach2, which option should I choose?
