With joy I noticed that the Artificial Horizon now properly updates also in the Ra-Dec mode silly.png
However, it now has a drawing error (both in Ra-Dec and Alt-Az modes) if features of the map "go backwards in azimuth" - see the attached image.  It's a tower with a larger platform on top, so there are points where Az decreases compared to the preceeding ones.  Here's an part of the Az,Alt values in that area:

     237.900      14.0500
      249.600      12.8500
      256.700      12.1000
      256.300      32.0500
      248.550      33.7000
      248.300      37.1000
      263.650      48.2000
      279.450      38.8500
      279.750      0.00000
      270.000      0.00000
It was rendered properly in the old version.
