Are you imaging or pure visual. I believe the 12" f5 would be ok for visual but I would not go bigger than a 10" if imaging. The General rule is to hold the imaging payload to 2/3s of the rated mount visual capacity - including the camera, guide stuff. I run a 10" f/5 ultra light imaging newt on my NEQ6 and its rock solid.
A 10" production newt, like a GSO/Bintel will weigh 15kg for the OTA once you add a camera, guidescope etc its going to be very close to the Skywatcher recommended 18kg limit for imaging. The 12" would be over the mounts recommended limit for imaging - however the visual limit is 25kg and the 12" would fit under that - but keep the tripod legs as short as possible to keep it steady.
Matt sorry fkr turning your sale thread into a discussion but he asked here. See if you can get a moderator to clean this up and delete the discussion .
