I have my new set up going ( using TSX and all drivers up to date) and noticed I had to recalibrate my AO-8T every time my position angle changes. Now we all know this should not be the way it works. What Jeff Dickermnan and I discovered on a remote session 2 days ago at my observatory was that the initial calibration works fine, but when the position angle is changed the AO glass guide vector is ALSO being rotated so the glass actually gets confused and tips the wrong way right off the guider FOV, the mount bumps were turned off, this is an AO issue but not sure on who's part....either Bisque or Diffraction. If you want more details Jeff from Optec will be happy to provide you with screen shots of the session. I was wondering if we could get this corrected? As always thanks!
