Congratulations on your purchase of an AstroMaster Series telescope. The AstroMaster Series of telescopes come

in several different models and this manual covers four models mounted on the CG-3 German Equatorial Mount ---

90mm refractor and 130mm Newtonian and then both of these sizes with a motor drive. 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.

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 equatorial mount with setting circles in both axes.

• 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.
