Just FYI, I bought a Mach2GTO because of my frustrations with AM5. I'm selling the AM5 and cannot recommend this mount for any serious astroimaging. It cannot handle the most basic park functionality and I've wasted over 1000 hours of troubleshooting and near damage to my scope because of this. At this point the AM5 is more of a toy for people doing mobile imaging from time to time which is fine but if you want to have a dedicated setup in a shed or observatory the AM5 is not the right mount.
