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.
