Not entirely true - it does if it’s a SynScan handset in altaz mode, makes a huge difference to the subsequent accuracy. You may think it’s fine with shorter scopes, but with a 3m focal length the errors on GOTOs are obvious.

Not sure what algorithm SynScan uses but one thing is clear - it’s not using the “the equivalent to that used by AstroDevices Nexus DSC or SkySafari, both of which utilise the “surveyors equation” and get it right.
