Well it can be done. After replacing the RA drive in my 12inch LX200ACF I had to test the scope out so I set it up next to the trusted 12inch LX200R (same optics, Mexican & USA assembled) in my 3x3 observatory. I had both imaging for supernova at the same time last night. Even with my small control room under roof of my 3x3 there was still enough room (just) to run the LX200R with a dew shield on a pier and the LX200ACF without a dew shield on its tripod & no chance of them banging into each other.
The ACF is the Leyburn weekend scope and the R is permanent in the observatory. They each have Moonlite focusers and Optec F7 & F6.2 reducers with a Starlight Xpress SXVH9 & SXVHR9.
