The bright supernova is visible adjacent to the bright core of galaxy NGC7331 40,000,000 light-years away.
Messier 10 is a very low target from 52°N and one which I had never considered photographing. The poor visibility is made worse by the poor southern horizon here. However, the short integration time has produced a remarkably good image of this beautiful globular cluster, helped by the stable sky this evening. This was really an experiment to check the collimation of the CT8 which turned out better than expected!
