  Hi Thomas, 

  On the NJP there are buttons to reverse the N/S or E/W slew buttons.

  One other thought.  Is it possible that you have the SkySafari chart set to "Flip Horizontal".  I'm thinking that the scope is moving correctly but the motion appears backwards on the chart because you have it flipped.  Go into the Settings > Coordinates to see if they are flipped.

  Thanks!

  This was very fast - thank's ! 

  Horizon not flipped.

  Tu change N/S doesn't change the reversed movement.

  But, aligne to Polaris, and not to a star in the south appear tu be the solution - you gonna tell me why.

  I informe you after further tests.

  I am copying info from another SkySafari community forum discussion with Bill Tschumy.  I do not know why you are having this issue.

  Hello - I did other tests with an alignment on Capella: everything works great. SkyFi 3  is an absolutely essential item for mounts without GoTo. Thank you very much !

  An excellent result, Thomas!  

  Please post what your solution was, or more specifically, if you now know, why did you have the inverted SkySafari controls to begin?

  Thanks!

  Hello

  I think the solution is to calibrate with a star heading east - I don't understand why, but calibrating on a star in the south reversed the direction of movement for my mount. It's an easy solution - maybe to note in the 'Quick Start Guide SkyFi 3' who says nothing about calibration before use. Thank's for support !

  Hello Keiron

  I hope I found an explanation for Skysafari-SkyFi's movements in the opposite direction : I had to turn the telescopic fix on my mount 90 degrees, and the movements became correct. I can imagine that this may be of interest to one or the other user.

  This explanation seems logical, as the spatial referential is turned upside down in either the eastern or western hemisphere, depending on the 90 degree or 180 degree mounting error - you have to test to find the correct position. SkyFi is not smart enough to be able to make a mistake ;-)
