NOTICE: CyberSky sales have stopped!

Due to my CyberSky astronomy software generating low revenue over the last year, Digital River MyCommerce, the company that has handled online sales and fulfillment for me for many years, has terminating my account.

The software business has changed dramatically since I first released CyberSky as shareware, a term I don’t think is used any more. I took the termination of my account as a sign I should retire, and have stopped sales of the program, effective May 3, 2024.

Thank you for your support, for sending me bug reports and a lot of suggestions to help me make CyberSky better, and especially for the many kind words you’ve sent me about my software over nearly three decades.


Getting help

If you have a question about using CyberSky that isn’t answered in Frequently-asked questions, please don’t hesitate to write.


Some problems you might encounter while using CyberSky may be due to a bug in a device driver. If a problem involves how objects are drawn on the screen, you might be able to fix it by updating the driver for your video card. Similarly, you might be able to fix a problem with printed maps by updating the driver for your printer. Some problems might be due to one or more corrupted files or Windows settings, and can often be fixed by uninstalling the software and then installing it again.

If you’ve discovered a bug in CyberSky, check to see if it’s been fixed in a newer version of the program. For more information, see Program updates.
