Uncooled and unguided, yes. It was also full moon, so I was sacrificing SNR by taking lots of very short subs, accepting the read noise penalty.

Thanks Trevor, I think the slight star bloat comes from the camera and high gain - the focus was tight. Anything more than about 10 sec with a high gain on this CMOS and the stars explode like supergiants!
