Bias/Dark subtract your guider images will solve pixel anomaly concerns. Also keep in mind that wide field guider setups need a longer calibration time. i.e. it takes longer for the guide star to move and determine the X and Y directions (orientation of guide chip). When I was guiding on axis with the FSQ and STL11k (internal guide chip), I calibrated both X and Y based on 20sec elapse times. This gave a strong reading between the X and Y axis providing the typical "L" shape. Longer focal lengths, the time can be reduced.

DITTO!
Feature rich guiding tools;
Can tweak aggressiveness (on the fly if desired), min and max movements, dithering, calibration frame reduction, sub frame grabs, scope declination compensation, binning, manual calibration, X/Y correction logging and graphing (in telescope or camera axis, with RMS). MaximDL remains the data acquisition tool of choice. Its the heavy artillery to get the job done.
