So visiting Dave one evening as we have not met for a while whilst I was updating software Dave processed the QHY268C data we took of M45.
So I’m disappointed that although the image is a good first start I forgot to change the change setting on the gain which in SGPro is in the event settings and not in the top level sequence display 🙁
Dave ran the image through the annotate function of PixInsight. The galaxy PGC13696 near the bottom of the image is actually 232 million light years away.
