Guiding error is under +/- 1 arcsec. 5 second guide exposures on a Losmandy Titan with a FSQ-106ED operating at 530mm FL. Hardly a challenge! Quadruple the FL and I'd probably be in for some edge of the seat excitement. Below is a MaximDL screen displaying the details. Such information probably doesn't help the cause, but this is what I routinely achieve. I should note, that the mount has been PEC tuned with PEMPro.

Reason: Sorry, I have an ED not N FSQ - fixed typo, not that it matters.
