2. Slide the mounting track at the bottom of th e Star Pointer over the dovetail portion of the bracket. It may be necessary to loosen the two screws on the sid e of the mounting track before sliding it over the dovetail. The end of the Star Pointer with the glass window should be facing out to wards the front of the telescope.
Attaching the NexStar to the Trip od The Celestron NexStar tripod is a sturdy, heavy duty mount on which to place your NexStar 4/5" telescope. This tripod can go anywhere, from your backyard to a remote observing site and can hold your NexStar in Alt-Az or can be polar aligned with the use of the built-i n equatorial wedge tilt pla te.
The NexStar has a removable hand controller built into the side o f the fork arm des igned to give you instan t access to all the functions the NexStar has to off er. With automat ic slewing to nearly 40,000 objects, and co mmon sense menu descriptions, ev en a beginner can master its variety of f eatures in just a few obs erving sessions.
4. Catalog Keys: The NexStar has a key on the hand control to allow direct access to each of the cata logs in its 40,000 object database. The NexStar contains the following catalogs in its database: Messier – Complete list of all Messier objects. NGC – Select list of all the deep-s ky objects in the Revised New General Catalog.
telescope. Finally, EQ North and EQ South alignments are designed to assist you in aligning the NexStar when polar aligned using the tripods built-in wedge. Each alignm ent method is discussed in d etail below. Sky Align Sky Align is the easiest way to get your NexStar aligned and r eady to observe.
4. Use the arrow buttons on the hand control to slew (move) the telescope towards an y bright celestial object in the sk y. Align the object with th e red dot of the finderscop e and press ENTER.
6. Based on this information, the NexStar will automatically display the most suitable second alignment star that is above the horizon. Press ENTER to automati cally slew the telescope to the displayed star.
Solar System Align Solar System Align is designed to pr ovide excellent tracking and GoTo perfo rmance by using solar system objects (Sun, Moon and planets) to align the telescope with th e sky. Solar System Align is a great way to align your telescope for daytime viewing as we ll as a quick way to align the tele scope for night time observing.
slew the telescope to the displayed s tar. If for some reason you do not wish to select one of these stars (perhaps it is behind a tree or building), you can either: • Press the UNDO button to display the next most suitable star for alignment.
Sync: The Sync feature can be used to improve poi nting accuracy in a s pecific region of the sky. S ync is a very useful feature especially when used in conjunction with the Con stellation tour an d Identify feature in which you will b e exploring smaller ar eas of the sky.
Slewing to an Object Once the desired object is displayed on the ha nd control screen, you have two op tions: • Press the INFO Key . This will give you useful information about the s elected object such as magnitude, constellation and fascinating facts about many of the objects .
D D i i r r e e c c t t i i o o n n B B u u t t t t o o n n s s he NexStar has four direction buttons in the cen ter of the ha nd control which control the telescope motion in altitude (up and T down) and azimuth (left and right). The telescop e can be controll ed at nine differe nt speed rates.
This rate compensates for the ro tation of the earth by moving the telescope at the same rate as th e ro tation of the earth, but in the opposite direction. When the telescope i s polar aligned, this can be accomplished by moving the telescope in Righ t As cension only.
Connecting a Camera to the NexStar Mount Your NexStar mount has a camer a control port that allows you to connect your camera using the s upplied Shutter Release Cable and a firing cable for your model of camera (not included). To connect you cam era: 1.
Repeat Count - Allows you to set the number of exposures per object. Exposure Time - Allows you to set the duratio n of each exposure in seconds. Long exposures – To take an exposure for more than 1 second, your cam era must be set to the “Bulb” setting.
S S c c o o p p e e S S e e t t u u p p F F e e a a t t u u r r e e s s Setup Time-Site - Allows the user to custom ize the Ne xStar display by changi ng ti me and loca t i on paramete rs (such a s time zone and daylight savings). Anti-backlash – All mechanical gears hav e a certain amount of backlash or play between the gears.
while polar aligned, you would want to set the azimuth approach to the dir ection that allows the sco pe to compensate for differ ent load level on the motors and g ears when pointing in different parts of the sk y.
Scrolling Menu This menus allows you to chang e the rate of speed that th e text scrolls across the h and control display. • Press the Up (number 6) button to increase the speed of the text. • Press the Down (number 9) but ton to decrease the speed of the text.

A telescope is an instrument that collects and focuses light. Th e nature of the optical design determines how the light is foc used. Some telescopes, known as refractors, use lenses.
Focusing The NexStar's focusing mechanism controls th e primary mirror which is mounted on a ring that slides back and forth on the primary ba ffle tube. The focusing knob, which moves the primary mirror, is on the rear cell of the telescop e just below the star diagonal and e yepiece.

Up to this point, this manual covered the assembly and basic operation of your NexS tar telescope. However, to understand your telescope more thoroughly , you need to know a little about th e night sky. This s ection deals with observational astronomy in general and includes information on th e night sky and polar align ment.
M M o o t t i i o o n n o o f f t t h h e e S S t t a a r r s s The daily motion of the Sun a cross the sky is familiar to even th e most casual observer. This daily trek is not the Sun m oving as early astronomers thought, but the result of the Earth's rotation.
Figure 6-3 This is how the telescope is to be se t up for polar alignment. The tube should be parallel to the fork arm which should be pointed to P olaris.
Based on your current alignment, NexStar will slew to wh ere it thinks Polaris should be. Use the tripod’s tilt plate adjustment to place Polaris in the center of the eyepiece . Do not use the hand control’s direction buttons to position Polaris .
Finding the North Celestial Pole In each hemisphere, there is a p oint in the sky around which all the other stars appear to rot ate. These points are cal led the celestial poles and are na med for the hemisphere in which they reside. For example, in the northern hemisphere all st ar s move around the north celestial pole.
With your telescope set up, you are ready to use it for observing. This section covers visual observ ing hints for both solar s ystem and deep sky objects as well as g e neral observing conditions which will affect your ability to observe.
S S o o l l a a r r O O b b s s e e r r v v i i n n g g H H i i n n t t s s o The best time to observe th e Sun is in the early mo rning or late afternoon when the air is cooler. o To center the Sun without look ing into the eyepiece, watch th e shadow of the t elescope tube until it forms a ci rcular shadow.
While your NexStar te lescope requires little m aintenance, there ar e a few things to remember that will ensure your telescope performs at its best. Care and Cleaning of the Optics Occasionally, dust and/or moisture ma y build up on the corrector plate of your telescope.
