First up I have changed the image and got rid of the purple look. Looks better to my eye.
Mike, I have done some unguided but only with the TSA on board. Those images showed no elongated stars. I would need to do a really big work out on PA to do unguided on the RC. Everything has to be well balanced though or else stars are pulling all over the place. Like you I love the mount, nothing wrong with that, it is the idiot driving it that is the problem really.

Not talking about you, talking about me.
That is interesting about your min motion setting. I am going to set this now and see how it runs next time. The seeing has been good at the observatory for the last 3 weeks or so. Interestingly I had the min motion some time ago set at 0.15 pixels and the guiding was good. See what I mean about the idiot driving it theme? Now I know why I had it set like that and I have reset it. With guiding images at 2.5 seconds this seemed fine. Thanks for the reminder Mike.
Alex it should be 0.68 I think which means I can sharpen heaps by virtue of oversampling. Only down side is the stars will be a little larger than I really want.
Always learning. Hope you like the colour now.
