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.
