I use my 900 GTO on a G11 pier, using a custom machined adaptor that bolts
on the 900SPA and the top of the pier.
The only thing I need when I setup my mount in my backyard is to remove the
scope and counterweight shaft.
I can easily carry the complete mount and pier outside whitout problem.
However, i am not Superman, Rolando will confirm ;-))
You can if you want remove the DEC axis in less than 5 seconds...OK, maybe
10....and the setup will be more easy to lift.
