9 If you wish to change the orientation of th e star diagonal, loosen the thumbscrew on the eyepiece adapter until the star diagon a l rotates freely. Rotate th e diagonal to the desired position and tighten the t humbscrew.
10 The Star Pointer comes equipped with a va riable brightnes s control, two axes al ignm ent control and mounting br ackets. Before th e Star Pointer is read y to be used, it m ust be attached to the telescope tub e and properly aligned : S S t t a a r r P P o o i i n n t t e e r r I I n n s s t t a a l l l l a a t t i i o o n n 1.
11 A A t t t t a a c c h h i i n n g g t t h h e e H H a a n n d d C C o o n n t t r r o o l l The NexStar SLT hand control has a phone jack type connector at the end of its cord. Plug the pho ne jack connector into the out let at the base of the t elescope’s fork arm .
12 T T h h e e H H a a n n d d C C o o n n t t r r o o l l The NexStar SLT's hand controller is designed to give you instan t acc ess to all the functions the NexStar has to offer.
13 5. Info : Displays coordinates and useful information about objects selected fro m the NexStar database. 6. Tour: Activates the tour mode, which se eks out all the best objects for a given month and auto matically slews the NexStar to those objects.
14 A A l l i i g g n n m m e e n n t t P P r r o o c c e e d d u u r r e e In order for the NexStar to accurately point to objects in the sk y, it must first be aligned to known positions (stars) in the sky. With this information, the tele scope can create a model of the sky, whic h it uses to locate an y object with known coordinates.
15 Time - Enter the current tim e for your area. You can enter either th e local time (i.e. 8:00 ), or you can enter m ilitary time (i.e. 20:0 0 ). Select PM or AM. If military time was en tered, the hand control will bypass this step. Choose between Standard time or Dayl ight Savings time.
16 A A u u t t o o T T w w o o - - S S t t a a r r A A l l i i g g n n As with Sky Align, Auto Two-Star Align re quires you to enter all the necessar y time/s ite informat ion as before. Once this information is entered, NexStar will prompt you to select a nd point the telescope at one known star in the sky.
17 Once the second star alignm ent is completed pro perly, the display wil l read Align Successful , and you should hear the tracking motors turn-on and begin to track. O O n n e e - - S S t t a a r r A A l l i i g g n n One-Star Align requires you to input all the same information as you would for the Two-Star Align procedure.
18 N N e e x x S S t t a a r r R R e e - - A A l l i i g g n n m m e e n n t t The NexStar has a re-a lignment feature whi ch allows you to repla ce either of th e original alignmen t stars with a n ew star or celestial object.
19 S S l l e e w w i i n n g g t t o o a a n n O O b b j j e e c c t t 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 th e selected object such as magnitude, constel lation and fascinating facts about many of the objects.
20 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 The NexStar has four direction buttons in th e center of the ha nd control which controls the telescope motion in altitude (up and down) and azimuth (lef t and right). The telescope can be control led at ni ne diffe rent spe ed rates.
21 Tracking Rate - In addition to b eing able to m ove the te l escope with the hand co ntrol buttons, the NexStar will continually track a celestial obje ct as it moves acr oss the night sk y.
22 Identify Identify Mode will search any of the NexStar database cata logs or lists and display the name and offset distances to the nearest matching objects. This feature can serve two purposes. Fi rst, it can be used to identify an unknown object in the field of view of your ey epiece.
23 Direction Buttons – The direc t ion a star move s in the eye pi ece vari es depending on the accessori es being used. This can create confusion when guidi ng on a star using an off-axis gu ider versus a straight through guid e scope. To comp ensate for this, the dire ction of the driv e control keys can be changed.
24 telescope up from hibernate mode. To wake up the telescope a fter UNDO has been pressed, select Hibernate from the Utility menu and press ENTER. Do not use the direction buttons to move th e telescope while in hibernate mode. Sun Menu For safety purpo ses the Sun will not be displayed as a database object unless it is first enabled .

26 Reversed from left to right, as viewed with a Star Diagonal Inverted image, as viewed with the eyepiece dir ectly in teles cope A telescope is an instrument that collects and fo cuses light. Th e nature of th e optical design de termines how the light is foc used.
27 Although the power is variable, each instrumen t under average skie s has a limit to the highest usef ul magnification. The gener al rule is that 60 power can be used for ever y inch of aperture. For example, the NexS tar 80 is 3.2” (80mm) in diam eter.
28 With your telescope set up, you are r eady to use it for obser ving . This section covers visual observing hin ts for both solar system and deep sky objects as well as general obser ving conditions which will affect your abili t y to observe.
29 For safe solar viewing, use a Celestron solar filter (see Optional Ac cessories section of manual) that reduces the intensity of the Sun's ligh t, making it saf e to view. With a f ilter you can se e sunspots as they move across the solar disk and faculae, which are bright patc hes seen near the Sun's edge.
30 Figure 5-1 Seeing conditions directly affect image quality. Th ese drawing represent a poin t source (i.e., star) under bad seeing conditions (left) to excellent conditions (r ight). Most often, seeing conditions produ c e images that lie some where b etween these t wo extremes.
31 While your NexStar te lescope requires little m aintenance, there ar e a few things to rem ember that will ensure your telescope performs at its best. C C a a r r e e a a n n d d C C l l e e a a n n i i n n g g o o f f t t h h e e O O p p t t i i c c s s Occasionally, dust and/or moisture may build up on the lens of your telescop e.
32 You will find that additional accessories enhance your viewi ng pleasure and exp and the usefulness of your telescope. For ease of referen ce, all the acc essories are listed in alphabe tical order. Adapter, Car Battery (#18769) - Celestron offers the Car Batter y Adapter that allows you to run the NexStar drive off an external power s ource.
33 Filter, Solar - The AstroSolar ® filter is a safe and durable filter th at covers the front op ening of the telescope. View sunspots and other solar features using this double-sided metal coated filter fo r uniform density and good color balan ce across the entire field.
