By Dr Andy McCrea Andy needs no introduction: as proprietor of North Down Telescopes, for many years he has been supplying amateur and professional astronomers throughout Ireland with all sorts of astronomical equipment from a complete observatory down to an eyepiece or filter. He’s also an accomplished astro-imager, with many excellent photos in Stardust and our exhibitions to his credit. If there’s anything he doesn’t know about telescopes, binoculars and astrophotography, it’s not worth knowing!

Abstract: Supermassive black holes, million to billion times more massive than the Sun, are now believed to lurk at the centre of every galaxy. Furthermore, it would appear that supermassive black holes "know" in which galaxy they live, as bigger galaxies contain bigger supermassive black holes and vice versa. This suggests that the formation of galaxies and the growth of supermassive black holes are tightly linked, which is surprising considering that despite their tremendous mass such black holes are still much smaller than their host galaxies, just like DNA molecules to a human body.
