Yes that guiding screen does not look correct it shows guiding there was movement and then no correction. Once i get calibration to work mine guides well i am too using a 14 inch scope a meade ACF. The only time you should get a display movement and no scope movement is if its in the dead zone area setting but i can see 5 pixels set so that should be ok, One think i do see different to mine is in the guiding rate box on mine there is no guiding rate option name just guide rates like 1x,2x,4x i normal used 1x or 2x try that.

Thanks - I think an important difference between your 14" and my 14" is that mine is Dobson Alt/Az mount and yours is a fork Alt/Az mount. My guess is you have considerably less backlash in your mount (hence the $7000 difference in retail price ). And yes, I've tried different guiding rates, it does not help. I have also tried adjusting backlash compensation in the Synscann app - also doesn't help. My thought is either need to upgrade the mount or figure out a novel mechanical solution to reducing the backlash in the gears. I do know one chap in Italy who put his SW 14" Dobson OTA on an EQ8 mount, but at that stage, I think it would make more sense just to upgrade to a Mead ACF 14 inch or similar - let me know when you are ready to sell As is think I've pushed my Dobson to its technical limits for AP and will meanwhile have to be content with guiding with ROI, better than nout!
