I did a very small tweak before imaging and here's the result. I've been giving manual guiding ago (seeing as I can't get my autoguiding to work
) but using K3 rather than look through a reticle. I like my comfort too much. Anyway...... this is a screen dump of over 2000 sec (for the mathmatically challenged over half an hour) with NO manual dec adjustment during that time. My drift error is much less in that time than the seeing condition (around 2"-3")
