10 With the bracket fi rmly attached to t he te le scope, you are ready to attach the finder to the bracke t. 1. Slide the O-Ring over the back of the fi nderscope and position it on the tube to ward the objective end of the finderscope.
11 P P o o w w e e r r i i n n g g t t h h e e C C P P C C The CPC can be powered by the supplied 12v car ba tter y adapter or optiona l pow er supply (see Optional Accessories section in the back of this manual).
12 The CPC is controlled b y Celestron’s NexStar hand contro ller de signed to giv e you instant a ccess to all the fun ctions the CPC has to offer. With automatic slew ing to over 40,000 objects, and common se nse menu descriptions, even a beginner can master its variety of features in ju st a few observing sessions.
13 Named Stars Common name listing of the bri ghtest stars in the sk y. Named Objects Alphabetical listing of over 50 of the most popular deep sky objects. Double Stars Numeric-alphabetical listing of the most visually stunning double, triple and quadruple stars in th e sky.
14 all these calculat ions and automaticall y entering the information f or you, the user sim ply needs to aim the teles cope to any three bright celestial objects in t he sky. Since Sky Align re quires no knowledge of the night sky it is not necessary to know the name of the stars that you are aiming.
15 loosening both clutches. However the following alignmen t stars still need to found and center ed using the hand control. • Remember to sel ect alignment st ars that ar e as far apart in the sk y as possible. F or best resul ts make sure that the third alignment s tar does not lie in a st raigh t line between th e first two stars.
16 T T w w o o S S t t a a r r A A l l i i g g n n m m e e n n t t With the two-star alignment method, the CPC requires the us er to know the positions of two bright stars in order to accurately align the telescope with the sky and begin finding objects.
17 1. Select Solar System Align from the alignment options. 2. Press ENTER to accept the time/site information displa yed on the display, or wait until the telescop e has downloaded the information fro m the GPS satellites. 3. The SELECT OBJECT message will appear in the top row of th e display.
18 EQ Two-Star Align The EQ Two-Star Align follows most of the same steps as the Alt-Az Two-Star Align. This alignment method does not require the user to align the altitude i ndex markers or point towards the Meridian, but it does require the user to locate and align the telescope on two bright stars.
19 CCD Objects. Selecting an y one of these catalo gs will displa y a numeric-alphabeti cal listing of the obj ects under that list. Pressing the Up and Down keys (10) allows you to scroll through the catalog to the desired object.
20 C C o o n n s s t t e e l l l l a a t t i i o o n n T T o o u u r r In addition to the Tour Mode, th e CPC telesc ope has a Constellation Tour that allo ws th e user to take a tour of all the best objects within a parti cular constellation.
21 a flat surface or tripod without the use of an equatorial wedge. The telescope must be al igned with two stars before it can track in altazim uth (Alt-Az). EQ North Used to track the sky when the telescope is polar aligned using an equatorial wedge in th e Northern Hemisphere.
22 Enter R.A. - Dec: You can also store a specific set of coordin ates for an object just b y entering the R.A. and declination for that object . Scroll to the " Enter RA-DEC " command and press ENTER. The display will then ask you to enter first the R.
23 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 customize th e CPC displa y by changing tim e and location param eters (such as time zone and daylight s avings). Anti-backlash – All mechanical gears have a certain amount of backlash or play between the gears.
24 If you want to explore the entire objec t database, set the maximum altitude limit to 90º and the minimum limit to –90º. This will display every object in the database lists reg ardless of whether it is visible in the sky from you r location.
25 Get Alt-Az - Displays the relati ve altitude and a zimuth for the current posi tion of the telescop e. Goto Alt-Az - Allows you to enter a specific a ltitude and azim uth position and slew to it. Hibernate - Hibernate allows the CPC to be completel y powered down and still retain its al ignment when turned back on.

28 Figure 5-3 The emblem on the en d of the focus knob shows the correct rotational d irection for focusing the CPC . the primary mirror only slightly. Therefore, it will take many turns (about 30) to go from close focus (approximately 60 feet) to infinity.
29 • Never look across or over objects that ar e producing heat waves. This includes asphalt p arking lots on hot summer days or building rooftops. • Hazy skies, fog, and mist can also make it difficult to focus when viewing terrestrially. The amount of detail seen under these conditions is greatly reduced.
30 Up to this point, this manual cove red the assembly and basic operation of your CPC telescope. However, to und erstand your telescope more thoroughly, you need to know a little about th e night sky. This section deals with observational astronomy in general and includes information on th e night sky and po lar alignment.
31 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 across the sky is familiar to even the most casual observer. Th is daily trek is not the Sun moving as early astronomers thought, but the re sult of the Earth 's rotation.

33 changes during the year and throughout the course of the night (s ee Figure 6-5). When the Big Dipper is low in the sky (i.e., near the horizon), it may be difficult to locate. During th ese times, look for Ca ssiopeia (see Figure 6-6). Observer s in the southern hemisphere are not as fortunate as those in the northern hemisphere.
34 Make the appropriate adjustm ents to the polar axis to elim inate an y drift. Once you have eliminated all th e drift, move to the star near the eastern horizon. The star should be 20 d egrees above the hor izon and with in five degrees of the celestial equator.
35 With your telescope set up, you are read y to use it for observing. This section covers visual observing hints for both solar s ystem and deep sky objects as well as genera l observing conditions which will affect your ability t o observe.
36 O O b b s s e e r r v v i i n n g g t t h h e e S S u u n n Although overlooked by many amateur astronomers, solar obser vation is both rewarding and fun. However, because the Sun is so bright, special precautions must be taken when observing our st ar so as not to damage your eyes or your telescope.
37 S S e e e e i i n n g g Seeing conditions refers to the stabilit y of the atmosphere and di rectly affects the amount of fine detail seen in ext ended objects. The air in our atmosphere acts as a lens which bends and distorts inco min g light rays.
38 After looking at the night sky for a while you may want to try photographing it. Several forms of celestial photography are po ssible with your telescope, including short exposure prim e focus, eyepiece projection, long exposure deep sky, terrestrial and even CCD im aging.

Always make exposures that are longer and shorter t han the recommended time.
40 Advance the film and you are ready for your next exposure. Don't forget to take photos of varyi ng duration and keep accurate r ecords of what you have done. Record the date, te lescope, exposure duration, eyepiece, f/rati o, film, and some comments on the seeing co nditions.

43 Lunar or small planetary nebulae-- f/10 imaging is more chal lenging for long expos ure, deep-sky im aging. Guiding needs to be very accurate and the exposure times need to be much longer, about 25 times longer than f/2. There ar e only a select few objects that work well at f/10.
44 While your CPC telescope requires little m aintenance, th ere ar e a few things to remember t hat 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 ma y build up on the corrector plate of your telescope.
45 Figure 9-3 A collimated telescope should appear symmetrical w ith the central obstruction centered in the star's diffraction patte rn. To accomplish this, you need to tighten the secondary collim ati on screw(s) that move the star across the field toward the direction of the skewed light.
