It may be possible to get some work done (if you can find anyone that 'tunes' them), but also be aware that even the best 'Professional' Observatory Mounts doing world-breaking scientific research have P.E.
It may be small but it is there. Anything mechanical will have some degree of error.
But autoguiding will compensate for average PE.
