7 This se ction c over s the as sem bly in structio ns for your Cele str on Adva nced Se ries T elesc ope ( AST). Your AST telescope should be set up indoor the first time so that it is easy to identify the various pa rts and familiarize yourself with the correct assem bly procedure before att empting i t outdoor.
8 1. Locate the azimuth adjustm ent screws on the equ atorial mount. 2. Retract the screws so they no longer extend into the azimuth housing on the mount. Do NOT rem ove the screws since they are needed later for polar alignm ent. 3. Hold the equ atorial moun t over the t ripod head so th at the azimu th housing is above th e metal peg.

10 place. As mentioned above, th ere are two R.A. shafts, one on either side of the mount. It makes no difference which shaft yo u use si nce bo th wor k the sa me. Use whiche ver o ne you fi nd more conve nie nt. If, aft er a fe w obser vin g sessions , you find the R.
11 Installing the F indersc ope To install the findersc ope onto the telescope y ou must first moun t the finderscope throug h the finder brack et and then attach it to the telescope. Tow ard the rear of th e telescope tube, near the focusing ass embly, there is a small bracket with a s et screw in it.
12 Eyepieces are comm only referred to by focal leng th and barrel diameter. The focal len gth of each ey epiece is printed on the ey epiece barrel. The longer th e focal length (i.e., the larger th e number) the lower the eyepiece magnification (i.e.
13 Like the R.A. balance, these a re general balance instructio ns and will reduce undue st ress on the mount. Whe n taking astrophoto graphs, this bala nce process should be done fo r the specific area at which the telescope is pointing.
14 latitude screw, first use the rear screw to raise the mount head all the way up. Then rem ove the front latitude scre w completely. Now you s hould be able to m anually move the mount head all t he way to its lo west latitude. Now, using only the rear screw, raise the mount to your desired latitude.
15 The Advanc ed Ser ies GT , comp uteri zed ve rsio n of eac h tel esco pe ha s a hand contr olle r de signed to gi ve you i nstant access to all the fun ctions that your telescope has to off er.
16 4. Catalog Keys: The Advanced Series has keys on the hand control to allow direct access to each of the catalogs in its database. The han d control contains th e following catalogs in its database: Messie r – Complete list of all Messier o bjects.
17 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 s s In order for the t elescope to accurately poi nt to objects in the sky, it mus t first be aligned to three known pos itions (stars) in the sky.
18 4. Select one of the f our alignment methods as described below. Note: If incorrect inf ormation is entered into the hand control, the UNDO button acts like a back space bu tton allowing the user to re- enter the correct data.
19 the eyepiece, press i ng ENTER when complete. NOTE: Although the telescope a llow s the user t o select the alignment stars, f o r best a ll-sky pointing accuracy it is still nece ssary to select t wo alignment st ars on one si de of the M eridian and t he third st ar on the opposi te side of the Meri dian.
20 O O b b j j e e c c t t C C a a t t a a l l o o g g Selectin g an Object Now that the telescope is prop erl y align ed, you can ch oose a n object from any of the catalogs in the telescope's extensive database. The h and control ha s a key (4) desig na ted for each of th e catalogs in its database.
21 Tour Mode The Advanced Series telescopes include a tour feature which automatically allo ws the user to choose from a list of interesting obj ects based on the date and ti me in which you are ob serving .
22 1 = .5x 6 = 64x 2 = 1x (s idereal) 7 = .5º / sec 3 = 4x 8 = 2º / sec 4 = 8x 9 = 3º / sec 5 = 16x S S e e t t u u p p P P r r o o c c e e d d u u r r e e s s The Advanced G T contains many us er defined setup funct ions design ed to give the user control over the telescope's many adv anced features.
23 that is not included in the regular database. There are sev eral ways to save an object to memory depen ding on what type of object it is: GoTo Object: To go to any of the user defined objects stored in t he database, scroll dow n to either GoTo Sky Obj or Goto Land Obj an d enter the number of the object y o u wish to select and press ENTE R.
24 Note: Some of the databases contain thousan ds o f objects, an d can therefore take several minutes to return the closest objects. Precise GoTo The Advanced Series telescopes have a precise g oto f.
25 example, if y ou are observing f rom a mountainous location where the horizon is partiall y obscured, y ou can set your minimum altitude limit to read +20º . This will make sure that the hand control only displays objects that are higher in altitude than 20º .
26 in R.A. (azimuth) until it reaches t he point that the cables a re extended to their maximu m. Then by displa ying the telescopes azimuth i n this po sition (by looking at Get A lt-Az under th e Utilities menu) you can determine the telescopes azimuth at its most extended position.
27 should be. Use the equatorial head latitude and azi muth adjustments to place Po laris in the center of the eyepiece. Do not use the direction buttons to position Po laris. Once Polaris is centered in the eyepiece press ENT ER; the polar axis should then be po inted towards the North Celestial P ole.

30 F F o o c c u u s s i i n n g g To focus y our telescope, simply turn the f o cus knob located directly belo w the f oc user. Turn i ng the knob clockwise allows you to focus on an obj ect that is f arther than the one you are currently observing .
31 Althoug h the p o we r is variable, each instrument un der average skies h as a limit to the highest u seful magnificati on. The gen eral rule is th at 60 power can be used for every inch o f aperture. For example, t he C6-R is 6 in ches in diameter.
32 Up to this poi nt, this m anual cov ered the assem bl y and ba sic operation of y our telescope. H o weve r, to understa nd your telesc ope more thoro ughly, you nee d to know a little about the night sky. This se ction deals w ith observ ational astronom y in g eneral and i ncludes information on the night sk y a nd polar alignm ent.
33 Motion of the St ars The daily motion of the Sun a cross the sky is familiar to ev en the m ost casual obser ver. T his daily trek is not t h e Su n mov ing as early as tronome rs thought, but the result of the Earth's rotation.
34 Latitude Scales The ea siest way to polar alig n a telescope is with a latitude scale. Unlike othe r methods tha t require you t o find the celes tial pole by identif ying ce rtain stars near it, this m ethod work s off of a k nown constant t o determine how high the polar ax is should be pointed.
35 Remember, w hile Polar aligning, do NOT move the telesc ope in R.A. or DEC. You do not want to move the telescope itself, but the polar ax is. The telescope is used simply to see w here the polar ax is is pointing. Lik e the pre vious m ethod, this gets you close to t he pole but not dir ectly on it.

37 With y our telescope set up, y ou are re ady to use it for observi ng. T his section cov ers visual obs erving hints for both solar sy stem and deep sky objects as w ell as general observi ng conditions w hich will aff ect your a bility to obser ve.
38 For safe solar view ing, use a solar filte r that reduces the inte nsity o f the Sun' s light, making it safe to view. W ith a filter y ou can see sunspots as the y m ove across the solar disk and faculae, whic h are bright pa tches seen ne ar the Sun's edge.
39 distu rbances vary from time-to- time and pl ace-to-place. The size of the air p arcels compared to your aperture determ ines the "seeing" quality. Under good se eing con d itions , fine detail is visi ble on the brighte r planets lik e Jupiter and Mars , and stars are pi npoint im ages.
40 Afte r looking at the night sky for a while y ou may want to try photographing it. Several form s of pho tography ar e possible w ith your tele scope, includi ng terres trial a nd celes tial photography . Both of these are discusse d in moderate detail with enough information to get you st arted.
41 5. Locate the area of the sky that you want to ph otograph and move the telescope so that it poin ts in that direction. 6. Find a suitable guide star in the teles cope eyepiece field of view. This is relatively easy since you can search a wide area w ithout affecting the area covered by y our camera lens .

The diagram below may be useful when connecting the CCD camera cable to th e telescope and calibrating the autoguider. Note th at the four outputs are acti ve-low, with internal pu ll-ups and are capable of sinking 25 mA DC.
