Congratulations on your purchase of the Celestron NexStar GPS telescope! The NexStar GPS ushers in the next
generation of computer automated telescopes. The NexStar GPS series, for the first time ever in a commercial
telescope, uses GPS (Global Positioning System) technology to take the guesswork and effort out of aligning and
finding celestial objects in the sky. Simple and easy to use, the NexStar with its on-board GPS, is up and running after
locating just two alignment stars. It’s so advanced that once you turn it on, the integrated GPS and digital compass
system automatically pinpoints your exact location and points to your first alignment star. No need to enter the date,
time, longitude and latitude or even know the position of north.
If you are new to astronomy, you may wish to start off by using the NexStar's built-in Sky Tour feature, which
commands the NexStar to find the most interesting objects in the sky and automatically slews to each one. Or if you
are an experienced amateur, you will appreciate the comprehensive database of over 40,000 objects, including
customized lists of all the best deep-sky objects, bright double stars and variable stars. No matter at what level you are
starting out, the NexStar will unfold for you and your friends all the wonders of the Universe.
Some of the many standard features of the NexStar include:
• Integrated Global Positioning System and electronic compass for hands free alignment.
• Fully enclosed optical encoders for position location.
• Ergonomically designed hand controller – built into the side of the fork arm.
• Database filter limits for creating custom object lists.
• Storage for programmable user defined objects; and
Many other high performance features!
The NexStar’s deluxe features combine with Celestron’s legendary Schmidt-Cassegrain optical system to give amateur
astronomers the most sophisticated and easy to use telescopes available on the market today.
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 NexStar, so you should keep this manual handy until you have fully
mastered your telescope’s operation. The NexStar hand control has built-in instructions to guide you through all the
alignment procedures needed to have the telescope up and running in minutes. Use this manual in conjunction with the
on-screen instructions provided by the hand control. 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 NexStar 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
Warning Warning
Warning
Y 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.
Y 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.
Y 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.
Y Never leave the telescope unsupervised, either when children are present or adults who may not be familiar
with the correct operating procedures of your telescope
