I recently posted a thread regarding the periodic error of my IEQ45 mount and have now had chance to program the PE data into the mount and run PEMPro again to check the improvement. PEMPro has reduced the error from 31.47 arc secs peak to peak to 9.08 arc secs peak to peak. The actual PE data/curves can be viewed at the following link
