ABOUT CELESTRON TABLE OF CONTENTS C14 • Rosette Nebula • Image courtesy of Richard Hedrick Celestron. Over 40 Years Of Telescope History A B O U T C E L E S T R O N 01 The history of Celestron dates back to 1957 when it was founded and incorporated as Valor Electronics by Mr.Tom Johnson, an electrical engineer and avid amateur astronomer. Mr. Johnson’s passion for telescope making became the basis for the future of his company. The name of the company was soon changed to Celestron.
INNOVATION C8 • Whirlpool Galaxy • Image courtesy of Sebastian Voltmer TELESCOPE TECHNOLOGIES Introducing Celestron's Revolutionary SkyAlign News “Flash” — Upgradeable Hand Controls! Pick three stars, any stars… Available with NexStar SLT, CPC and C20 Astrograph Telescopes… Aligning your telescope is easier and faster than ever. Simply input the date, time and your location (GPS models obtain all this information automatically) and then point the telescope at three bright stars of your choosing.
TELESCOPE BASICS C14 • Dumbbell Nebula • Image courtesy of Ted Inoue TELESCOPE CHARACTERISTICS This section looks at the separate component parts of a telescope. This will help you in making important decisions when selecting a telescope model. This section also discusses the uses of a telescope for astronomy or terrestrial (land viewing) use. It is important to read this section if you aren't sure which Celestron telescope product is right for you.
TELESCOPE BASICS C8 • Moon • Image courtesy of Sebastian Voltmer MOUNT AND TELESCOPE TYPES Altazimuth vs. Equatorial (cont.) These type mounts are good for terrestrial observing and for scanning the sky at lower power but are not advised for deep sky photography. Both Altazimuth and Equatorial mounts can track the stars sufficiently for visual use, however, only equatorials can be used for long exposure astrophotography.
TELESCOPE BASICS C14 • Horsehead Nebula • Image courtesy of Richard Hedrick TELESCOPE TYPES Newtonian Reflector Telescope A Newtonian reflector uses a single concave mirror as its primary. Light enters the tube traveling to the mirror at the back end. Light is then “bent” forward in the tube to a single point, its focal plane. A flat mirror called a “diagonal” intercepts the light and points it out the side of the tube at right angles to the tube through the eyepiece.
