Thanks all
I use a Q guider camera and watch it on the laptop, keeping the star centred on a virtual recticle. I do several hours at a time, and have digital TV in a window so I can watch TV and guide at the same time. I will occasionally grab a coffee or hot milo between subs then come back and sip it while guiding.
I deliberatly put the scope slightly off balance so the worm meshes with the plastic drive wheel, and it will track surprisingly well if theres no wind about.
