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]
- Photo-to-visual conversion [p,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.

QZ Carinae paper by David Blane
I recently participated in a mammoth international collaboration to improve our understanding of the enigmatic multi-star system, QZ Carinae. I am pleased to report that the paper has been accepted by Astronomy & Astrophysics and will be published in due course. This is the third publication on this eclipsing binary system we have published in recent years!
The pre-publication details are available on arXiv:2204.07045.
A Bit of Sky Guide History
The first edition of this Sky Guide was published in 1946 and was known as the Astronomical Handbook for Southern Africa. It consisted of 12 pages and was available for 1/6 from Juta and Co., Darling Street, Cape Town. Dr Richard Hugh Stoy of the Royal Observatory carried out most of the calculations, assisted by Mr Reginald de Kock, Dr Alan Cousins and other members of staff. In 1957 the book was redesigned and most of the calculations were performed by the Transvaal Centre’s Computing Section. In 1962 the Handbook was sold for 25 cents, and the Royal Observatory was again responsible for generating the data. In 1974, Dr Tony Fairall at the UCT Astronomy Department took over as editor. The next 13 issues were edited by Mr Rupert Hurly until Ms Pat Booth took over in 1990. During 2003, a committee consisting of Auke Slotegraaf, Maciej Soltynski and Cliff Turk, assisted by many helpers, redesigned the Handbook. After much deliberation the name was changed to the Sky Guide.
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!
