mass produced. It is estimated there are only 500 Compustar 14 telescopes, a number smaller

than any other commercial model.

Fortunately, this is not at all necessary. By building the autoguider relay assembly and

connections described in this article, any Compustar can be autoguided and used to obtain

beautiful long-exposure astrophotographs.

The author has endeavored to increase awareness and appreciation for the Compstars by posting

images obtained with his Compustar 14 on several websites, including the Reader Photo

Galleries of Sky and Telescope and Astronomy magazines, as well as Celestron‟s

astrophotography website, CelestronImages.com. Some of the images have been selected as

“Editors‟ Choice” by Sky and Telescope. Celestron uses some of these images as background

astrophotographs on their main Celestron website. Celestron has also selected more of these

images for display on their website as examples for demonstrating what the optics of the C14 are

capable of than from any other astrophotographer using any other version of the C14. This has

helped, however much, to keep the Compustars in the public eye and recognized as some of the

most valuable telescopes that Celestron has ever produced. It is the author‟s hope that this article

will provide other Compustar owners with the capability of autoguiding their astrophotographs

using these amazing telescopes.

Acknowledgements

The author wishes to thank Mr. Dennis Borgman for his published wiring diagram for the relay

box connections between the RJ-11 cable and the DB-9 connector on the Compustar computer

module. Publication of his diagram has made autoguiding the Compustar possible for the author

and, hopefully, many others.

The author gratefully acknowledges the generous assistance of Mr. Tom Sorbel of StarChron

Solutions, Plymouth, MN. Tom already deserves tremendous credit for the countless hours he

has devoted to developing the Y2K chip for the Compustars and updating the Compustar

database in the Y2K+ chip. These chips are the reason that Compustar owners can continue to

use and enjoy their Compustars throughout the 21

century. Tom donated many hours of his time

helping the author produce this manuscript, providing encouragement, assistance with technical

issues, testing of electrical circuits, and editing. His extensive knowledge of the Compustar

electronics, computer module, and its programming is, in the author‟s opinion, unmatched.

Thank you, Tom.

Lastly, the author wishes to acknowledge Mr. Alan Younis, electrical engineer, for building the

relay box, relay circuits and connections for the Compustar (the very one shown in this article).

His willingness to take on this project and see it through to completion has made guiding the

author‟s Compustar a reality.
