When using the SkySafari INDI driver / interface on the StarGO2 Pro, it inverts DEC values between -1° and 0°. The values become positive and the mount slews to the opposite side of the celestial equator. E.g. -0° 27' becomes +0° 27'.
I could confirm this with three stars in Pisces: 12, 13, and 14 Piscium. For the first two, the mount goes to the opposite side of the equator, for the last one it goes to the star correctly. Even plate solving cannot fix this, obviously.
I noticed this first on the ASIAIR with Jupiter this week:
Then directly in SkySafari 6:
And in SkySafari 7, I can use the native INDI driver of the mount and everything is OK:
StarGO2 and ASIAIR still have communication issues, so only the SS INDI driver can be used and keeps showing this issue for Jupiter, M2 and a few other objects close to and just below the equator.
