Agree Steve. After a bit of tweaking and adjucting I found my EQ3 and RA motor did a commendable job for widefield. Actually I was quite pleasantly surprised after running the RA through K3 with a ToUcam in place at how good the periodic error was. Mind you there are EQ3s and then there are EQ3s. Mines the one that comes with the Celestron HD-102eq refractor which is basically the same as the
C4-R package put together by celestron.
