I do have backlash that needs adjusting on the Dec but the RA has no slop movement or backlash it's perfect....and thats where the PEC needs adjusting...I am not getting much PEC on the dec axis.....thats fine....all this has to do with the RA axis.

I did pec training manualy but with the use of the toucam so I was visualy looking at it on the monitor instead of constinently looking through a iluminated reticle eyepiece.

Pec training was easy...I could see I needed to make large corrections on just the 1 axis but this was no problem..I had the star centered very well for the entire 4 mins.....I even did the PEC training 3 times in a row again.

The star I was using was around 10-20 degreez of the meridian.

I have balanced the mount.

Here is diagram I just made up on what is happening regarding star movement on the RA axis...this is approx 2800mm focal length with a toucam.
