I am using a G-11 and gemini 2 and a 10" reflector.
I know I have PE. I used pempro, and I had consistent error over 8 worm cycles. I uploaded a new curve to the mount, and there was an improvment.
I took a few images of M41 las night, with Guiding on/off, PEC, and no guiding at all. To me it looks like the guider is over-corecting, however the drift direction does not correspond to the N-S E-W direction of my test image? This makes me think there may be some Coma involved also. I have a MPCC, which is spaced out roughly the correct 55mm from the sensor. The large stars appear round though?
The unguided image is the bet I think.
Should I maybe set the RA Agresivness down really low, or check the spacing of the coma corector?
