Continuing the honeymoon that was first publicized at the SBIG CCD Imaging Conference held at Santa Barbara, California in July of 1996, Celestron International of Torrance, California has announced that they will offer an economical yet fully functioned version of the very popular Software Bisque astronomy program "TheSky".

is a full-featured graphical astronomy program that can show you what's up in the sky on any date, from any place on earth. Regarded as the premier program for learning about and enjoying the fascinating past time of astronomy, TheSky has features to benefit a wide range of interest levels from the beginning hobbyist to the seasoned professional.

The version licensed for exclusive distribution by Celestron will be a Level I version with all of the functions as TheSky, but with a smaller database than that furnished by Software Bisque and its distributors (including Company Seven) in TheSky Level II, II, or IV.

TheSky is distributed on one CD-ROM. It uses the Microsoft WindowsTM user interface so you can experience the power of the program instantly. Master "TheSky" with complete on-line help -- it puts the entire 150-page manual (included) at your fingertips. The on-line tutorial helps you learn terminology and understand sophisticated astronomical concepts. For example, to learn the definition of "Precession" simply type it in. The search function displays the definition instantly. The tutorial also comes with scores of illustrations. TheSky Level I includes data about the major planets, the Sun, and the Moon, and thousands of other celestial objects of interest.
