Congratulations on your purchase of the Celestron NexStar! The NexStar ushers in a whole new generation of computer
automated technology. Simple and friendly to use, the NexStar is up and running after locating just two alignment stars.
It’s the perfect combination of power and portability. 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 4,000 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:
• Incredible 4°/second slew speed.
• Fully enclosed motors and optical encoders for position location.

• Storage for programmable user defined objects; and
Many other high performance features!
The NexStar’s deluxe features combined with Celestron’s legendary optical standards give amateur astronomers one of 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
Never look directly at the sun with the naked eye or with a telescope (unless you are using 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.
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
