Recently I resolved the issues I was having with getting meridian flips to work with SGPro, TheSkyX and my Paramount MX+ Mount. I determined that the Flip Hour Angle set on TheSkyX needs to correspond with that for SGPro, otherwise the OTA can end up on a different side of the pier to what SGPro is expecting. Therefore if I set the Flip Hour Angle on TheSkyX to 0 degrees and set the minutes past the meridian to flip also to zero degrees to 0, everything works perfectly. Equally, if I want to delay the flip until 60 minutes after the meridian, I can set the Flip Hour Angle to +60 minutes on both and once again it works fine. There may also be occasions where I would like to flip before the Meridian. However, when I tried to set a negative number in the “Minutes past meridian to flip” dialogue box in SGPro I got an error message saying ‘Your mount does not allow pier flips prior to crossing the meridian and your “Degrees past the meridian to flip” has been set to 0.’
Why not? From within TheSkyX, I can flip to either side of the Meridian with the press of a button, as long as the OTA is pointing within the slew limit envolope each side of the meridian.
Is this an issue with the ASCOM Driver for The Sky or SGPro?
