Mick, my first attempt at guiding (by hand) was at camp last weekend, and I found that it certainly improves an image.
I hand guided about 6 images of varying lengths, then stacked them.
I think the images are supposed to be the same lengths, dunno, but I was experimenting and I finally got some better results.
Your stars look round, so you must be doing it right.
Damn hard this hand guiding caper
