CHAPTER 1 - INTRODUCTION
Congratulations on your purchase of a Celestron Ultima 2000! The Ultima 2000 ushers in a whole new generation of
computer automated technology. Simple and friendly to use, the Ultima 2000 is up and running after locating just two
alignment stars. And then the fun begins. Start off with our built-in Sky Tour package or begin to observe any of the over
10,000 objects in the standard data base. The Ultima 2000 will unfold for you and your friends the wonders of the
planets, stars and galaxies. You may even discover and track your own comet!
Many of the standard features of the Ultima 2000 have never been available previously:
•
Incredible 10°/second (or faster) slewing speed;
•
Fully enclosed optical encoders for position location - you can manually move the telescope and it will still know its
location;
•
Precision worm drive on both axes;
•
Radical and innovative new fork mount;
•
Extremely low power consumption - runs off 8 AA batteries for 20 hours under normal usage;
•
CCD compatible, auto-guider ready;
•
RS-232 port allows use of PC’s; and
•
Many other high performance features!
The Ultima 2000’s deluxe features combine with Celestron’s legendary Schmidt-Cassegrain optical system to give
amateur astronomers the most sophisticated visual and photographic telescope 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 Ultima 2000. The laminated summary sheet has a very useful diagram
that will demonstrate access to the different menus of operation. Also, you should keep this manual handy until you have
fully mastered your telescope’s operation.
Your Ultima 2000 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: Be careful with solar observing
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.
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.
Never point your telescope at the sun unless you have the proper solar filter. When using your telescope with the correct
solar filter, always cover the finderscope. Although small in aperture, the finderscope has enough light gathering power to
cause permanent and irreversible eye damage. In addition, the image projected by the finderscope is hot enough to burn
skin or clothing.
