I am specifically looking for the older version of pier extension where the bottom plate can flipped around to create a "flat" surface to mount on a CPC 1100 tripod. They have changed the design in the newer version which doesn't allow this...
Let me know if you have one for sale. Happy to pay for shipping...
I think I might have what you are looking for. I did a test today on my EQ6R pier and yes the bottom can be flipped flat. Let me send you some photos and you can confirm.
