Home page of Hartmut Winkler

Welcome to my home page! I have populated it with links that relate to me, my work or my hobbies. You may find some useful. Functional with no frills.

In the menu on the left you will find links to the pages of various large larger projects where I have collected a lot of data.
This includes the Z-limited AGN Catalogue (ZAC), the South African solar power station database and details related to the Eskom grid.
I have also included a special page listing my academic papers and articles and interviews that have appeared in the media.

Lower down I present useful links, which I have grouped according to the following categories:
Astronomical observation links -
Astronomical databases -
News sites -
Ancestry research -
Mythology -
Art gallery - virtual galleries, artwork discussion, famous artists
Film - streaming sites and film analysis
