I've only had one day setting up my MX due to clouds etc and, hopefully, tonight will be clear for another go. The main thing I noticed was when slewing to a star and then centreing it to the cross hair on the camera image. I overshot the correction by half the width of the diffraction spikes and the MX responded immediately to the new correction. NO BACKLASH! I am still impressed. I even vacuumed some dust off the MX today!!
All in all, with my limited experience, I am happy. I also found a bug in TheSkyX (only applies to SA users) which will be fixed in the next release so the folks at Bisque are very responsive.
