The Lx200 12" OTA (bare) weighs in at 17.1Kg....
add the cameras, minirails etc etc and you'll be up close to 20Kg+
The G11 is rated for 60 lbs (27Kg) - so it should handle it well.
( I looked at de-forking my Lx 12" for spectroscopy but couldn't find a mounting I could afford to replace the functionality (and GOTO) of the original fork..well outside the comfort zone of a NEQ6pro. Ended up selling it and replaced with a C11 on an NEQ6pro -majic!)
