I take it that you are able to calibrate OK? How much PE do you have? Guiding a 90mm refractor is going to be a lot easier than a larger scope with I assume a long focal length. In fact you may need to guide through your imaging scope with an OAG to expect a decent result and to avoid flexure between your guide scope and OT.

Calibration seems to work fine - no idea what the PE is but i suspect it will be nasty
last night I went back to using the 90mm refractor, and the results where the same - sine wave RA pattern when guiding, and poor results.
Im starting to think I may have damaged the mount..
btw, the skywatcher scope is around 1000 mm, so I thought a finder guider would work...
