Introduction

Beyond the Sun, Moon and planets lie the stars of our Galaxy. Some are grouped together in clusters, others are spread out along the plane of the Galaxy along its spiral arms, a region rich in nebulae (vast clouds of gas and dust). Far beyond our Galaxy we encounter other galaxies, clusters of galaxies and quasars. These objects – galaxies, star clusters and nebulae – are what deep-sky observers study. (Historically, no distinction was made between what we today call nebulae, and galaxies – these “faint fuzzies” were lumped together as ‘nebulae’.) To find out more about these objects, visit the “Observing deep-sky objects” page.

Current projects

Some of the projects currently being worked on, include:

  • An Observer’s Atlas of the Large and Small Magellanic Clouds [o,p]
  • Documentary Film: Into the Deep
  • Dark Nebula Atlas [o,p]
  • Digital Archive of Historical Deep-Sky Texts [r]
  • Historical Archive of the Visual Deep-Sky [r]
  • Biographical Notes: Who’s Who of the Deep-Sky [r]
  • Deep-Sky Nick-names [r]

  • Telescopes in movies: The good and the bad [r]
  • Deep-sky marathons [o]
  • Big 5 of the African Sky / Groot 5 van die Afrika Nag [o]

Key:
[o] = observing project
[p] = has a significant astrophotography component
[r] = lots of reading/research/desk work involved

If you’d like to get involved in any of these projects, or initiate one of your own, please get hold of me.

Big 5 of the African Sky

The “Big 5 of the African Sky” is an invitation to witness the most spectacular deep-sky treasures of the southern hemisphere: five objects that represent the best of the best!
