TM An All EHCOIOaSSing Astronomy Pr ogram ‘ 2 “SKY TRAVEL,’ known as the fastest, friendliest and most popular astronomy program for personal computers, was created by Deltron Ltd. and first published by Commodore in 1984. Deltron was founded by three friends, Dr. Frank Covitz, Dr. Clif Ashcraft and Dr. Fred Ancker, all chemists. With becoming modesty, they decided to model the universe as their first software product; Clif fashioned it, Frank iteezs itinto the Commodore 64, and Fred wrote the book. They describe each other as follows: Dr. Frank graduated from Harvard with a Ph.D. in Chemistry. As a student, he supported himself partly by playing pool while he entertained himself by working with the astronomers at Harvard Observatory on the development of a guider for their large telescopes. Sky Travel Developers: Dr. Fred Ancker, | In 1974, he wrote a 3-part article with Dr. Clif for Sky and Telescope Dr. Frank Covitz, and Dr. Clif Ashcraft (March/April/May) on auto-guiders and deep-sky photography. Frank also wrote an account of the early history of “SKY TRAVEL” for Toronto PET User Group magazine in May 1985. He is recognized as a pioneer in computer music, and has simply too many interests to list. Dr. Clif graduated from University of California (Berkeley) with a Ph.D. in Chemistry, while he studied astronomy on the side. Clif has been grinding lenses and built telescopes since childhood and became interested in the use of computers in astronomy when using trigono- metric ray tracing on an IBM 1130 to design a 10-inch refractor for the Sperry Observatory at Union College, N.J. Clif isan accomplished amateur actor and has a tolerable tenor voice, wh…
