I have posted a new revision with the white stars that the tone mapping process produces instead of my previous attempt at fake star colour. Next time I'll make sure to get some RGB.
Leo: thanks for the kind offer of RGB stars but unfortunately your image doesn't cover one corner of my FOV, so I'd have to do an odd crop.
