A Planetarium and Telescope Control Program for Windows
New Items:
- 24 January 2025: ECU V6.2 has been released. This is just a minor housekeeping update.
- 6 June 2020: ECU V6.2 has been released. This is just a minor housekeeping update to V6.1F.
- 4 June 2020: ECU V6.1F has been released. There are several improvements and bug fixes. See the upgrade page for details.
- 4 March 2017: 25 years ago I released (as shareware) the first version of my Earth Centered Universe Planetarium/Telescope Control software. At the time, it was the first such program in the world available for the (new) Microsoft Windows 3.0 operating system.
- While the customer base now is small, it is still being developed when I can spare the time (a major new version came out this time last year).
- It all began about 6 months earlier when I was challenged by my "mac" astronomy friends to write something as good as the Voyager software, so I did!
- Before long, money starting arriving in the mail and I had to startup a business "quick" - and its been going every since!
