Interesting, I am asuming that you have taken a number of Darks the same length as your light exposures, a similar number of Bias on your shortest exposure. Sounds like you may have missed a step somewhere.
Your DEC backlash is large although I would have thought that you could manually import a number of seconds to calibrate, with the G-11 I have to set my backlash compensation at 12 seconds to get the mount to move the required 9 pixels, it is nothing unusual to have this setting up around 20 - 25 seconds. Is there a way to adjust the Aggressiveness, on the ST-4, I have this set at 3-5 depending on the seeing.
And, yes, good alignment helps, if you want, send me a PM with your email address and I will send you a PDF file with Southern Hemishere Drift Aligning explained.
