Sounds like you are seriously misaligned.

3.5.3 Modeling Parameters
Gemini models the following mount and telescope parameters:
Azimuth misalignment from the pole
Elevation misalignment from the pole
Axis non-perpendicularity at the pole
Axis non-perpendicularity at the equator
Gear play
Mirror flop
Index error in hour angle
Index error in declination
Counterweight flexure
You can examine each of these parameters immediately after an additional alignment. The azimuth and elevation misalignment (
A and E) are displayed right after the “Additional Align” is executed. You can also use the “Show Information” menu item to display the other parameters: NP = non-perpendicularity at the pole, NE = nonperpendicularity at the equator, FR = gear play (in RA), FD = mirror flop (in Dec.), IH = Hour Angle index error, ID = declination index error, and CF = counterweight flexure. All values are given in minutes of arc. These values give you valuable information about your alignment, your mount and your telescope.
