Professor E. J. Hartung first produced a comprehensive and highly respected guide for southern observers in 1968.

This book was then revised in 1995 by David Malin, who was previously the astrophotographer at the Anglo Australian Telescope, and by David Frew, an astronomer at Macquarie University here in Sydney.

This book is cherished by many southern observers and Peter Marples produced an Argo Navis user catalog from the list of objects described in the book.

For anyone new to southern skies, this book and catalog make for a wonderful starting point.

David Moorhouse in New Zealand kindly produced these lists of Hartung objects in Excel and CSV formats which was published on the Argo Navis Users' Group.

This Excel Spreadsheet was created by "cozens3" and contains a list of all NGC & IC objects that appear in Hartungs. They have been ranked in order of magnitude.
This list originally appeared on the Argo Navis Users' Group.
