Towards top left of this image you can see the elongated trail of asteroid 12 Victoria. Around 50 subs at 3-minutes per sub with the Hyperstar III - bright Moon and a lot of thin high cloud but the asteroid still shone through. The bright star should be red. One thing to note, the images were dithered so that I could remove all the hot pixels with SDMask stacking - except if you use SDMask staking then it treats the asteroid trail as outliers and you lose your asteroid :( So it is necessary to average stack which means you then need to manually remove all the hot pixels which is a right pain.
