Cosmetatos

Hi, I have done pretty much the same setup, but I have a slight problem. The evoguide has a focus lock screw, which you need to have unscrewed for the auto focus routine to work. However I have found that this leaves a slight wobble on the focuser that results in tilt. So, after the auto focus I need to tighten the screw which does not allow me to refocus during the night. Have you had this problem?
