Congratulations on your purchase of an AstroMaster Series telescope. The AstroMaster Series of telescopes come
in several different models and this manual covers three models mounted on the Alt-AZ Mount ((an altazimuth is
the simplest type of mount with two motions – altitude (up & down) and azimuth (side-to-side)))-- 70mm refractor,
90mm refractor, and 114mm Newtonian. The AstroMaster Series is made of the highest quality materials to ensure
stability and durability. All this adds up to a telescope that gives you a lifetime of pleasure with a minimal amount
of maintenance.
These telescopes were designed for the First Time Buyer offering exceptional value. The AstroMaster series
features a compact and portable design with ample optical performance to excite any newcomer to the world of
amateur astronomy. In addition, your AstroMaster telescope is ideal for terrestrial observations which will open
your eyes with superb high power viewing.
AstroMaster telescopes carry a two year limited warranty. For details see our website at
www.celestron.com
Some of the many standard features of the AstroMaster include:
• All coated glass optical elements for clear, crisp images.
• Smooth functioning, rigid alt-azimuth mount with a large pan handle with built-in clutch for easy targeting.
• Preassembled steel leg tripod with 1.25” legs ensures stable platform.
• Quick and easy no-tool set up.
• CD-ROM “The Sky” Level 1 --- astronomy software which provides education about the sky and printable sky
maps.
• All models can be used terrestrially as well as astronomically with the standard accessories included.
Take time to read through this manual before embarking on your journey through the Universe. It may take a few
observing sessions to become familiar with your telescope, so you should keep this manual handy until you have
fully mastered your telescope’s operation. The manual gives detailed information regarding each step as well as
needed reference material and helpful hints guaranteed to make your observing experience as simple and pleasurable
as possible.
Your telescope is designed to give you years of fun and rewarding observations. However, there are a few things to
consider before using your telescope that will ensure your safety and protect your equipment.
Warning
• Never look directly at the sun with the naked eye or with a telescope (unless you have the proper
solar filter). Permanent and irreversible eye damage may result.
• Never use your telescope to project an image of the sun onto any surface. Internal heat build-up can
damage the telescope and any accessories attached to it.
• Never use an eyepiece solar filter or a Herschel wedge. Internal heat build-up inside the telescope can
cause these devices to crack or break, allowing unfiltered sunlight to pass through to the eye.
• Do not leave the telescope unsupervised, either when children are present or adults who may not be
familiar with the correct operating procedures of your telescope.
