7 This se ctio n cover s the a sse mbly in structi ons for your Cele str on Ad vanced Series T ele scop e (AST ). Yo ur AST telescope should be set up indoor the first time so that it is easy to identify the various p arts and familiarize yourself with the correct assem bly procedure before att empting i t outdoor.
8 A A t t t t a a c c h h i i n n g g t t h h e e E E q q u u a a t t o o r r i i a a l l M M o o u u n n t t The equatorial mount allows you to tilt t he telescope’s ax is of rotation so that you can track the stars as they move across the sky. The CG-5 m ount is a German equ atorial mount that attaches t o the tripod head.
9 I I n n s s t t a a l l l l i i n n g g t t h h e e C C o o u u n n t t e e r r w w e e i i g g h h t t Depending on which AST telescope y ou have, you will receive either one or tw o counterweights. To install the count erwe ight (s): 1. O rient t he mo unt so that t he c ounter wei ght ba r po ints to ward the ground .
10 The knob is a tension fit, so sliding it on holds it in place. As mentioned above, there are tw o R.A. shafts, on e on either side of the mount. It makes no diff erence which shaft you use since both work the same. Use whichever one you f ind more convenient.
11 3. Hold the visual back with the set scre w in a convenient position and rotate the knurled slip ring cloc kwise until tight. Once this is done, y ou are ready to attach other accessories, such as eyepieces , diagonal prisms, etc. If you want to remove the visual back, rotate the slip ring counterclockwise until it is free of the rear cell.
12 • Finders cope • Finder Bracket • Ru bber O- ring • Three Ny lon Tipped Thum bscrews (10- 24x1/2") • Two Phillips Head Screws (8-32x1/2" ) To install the finderscope: 1. Attach the bracket to the optical tube. T o do this, place the curved portion of the bracket with the slot over the tw o holes in the rear cell.
13 M M o o v v i i n n g g t t h h e e T T e e l l e e s s c c o o p p e e M M a a n n u u a a l l l l y y In order to properly balance your telescope, you will need to move your telescope manually at various portions of the sky to observ e diffe rent objects.
14 B B a a l l a a n n c c i i n n g g T T h h e e M M o o u u n n t t i i n n D D E E C C Although the telescope do es not track in declination, the telescop e should also be balanced in this axis to pr event any sudden motions when the DEC lock lever is loose.
15 For Advanced GT users, it may be helpful to remove the front latitude adj ustment screw completely. This will allo w the mount to reach lower latitudes withou t the screw coming into con tact with the R.A. motor assembly. To rem ove the latitude screw, first us e the rear screw to raise the m ount head all the way up.
16 The Advanc ed Ser ies GT , comp uteri zed ve rsi on of ea ch te lesc ope has a ha nd co ntrol ler d esigne d to gi ve you inst ant access to all the fun ctions that your telescope has to off er.
17 4. Catalog Keys: T he Advanced Series has ke ys on the hand control to allow direct access to each of the catalogs in its database. The han d control cont ains the following catalogs in its database: Messie r – Complete list of all Messier o bjects.
18 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 ele scope to accurate ly point to objects in the sky , it must first be align e d to three known posi tions (stars) in the sky.
19 4. Select one of the four alignm e nt meth ods 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- e nter the correct data.
20 4. As with the Auto Al ign procedure, y ou will be asked to cen ter the star in the cross hairs of the finderscope and th en ce nter the star in the eyepiece, pressing ENTER when complete.
21 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 Selecting an Object Now that the telescope is prop erl y align ed, you can choose an 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 catalo gs in its database.
22 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 o bserving.
23 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 io ns design ed to giv e the user control ov er the telescope's many adv a nced features.
24 GoTo Object: To go to any of the user defin ed obj ects st ored in the database, scroll down to either GoTo Sky Obj or Goto Land Obj an d enter the number of the object y ou wish to select and press ENTE R. The telescope will automatically retrieve and display the coordinates before slewing to th e obj ect.
25 Precise GoTo The Advanced Series telescopes have a precise g oto function that can assist in finding extremely faint objects and centering objects closer to th e center of the field of view for astrophotography and CCD imaging.
26 minimum altitude limit to read +20º . This will make sure that the hand control only displays objects that are higher in altitude than 20º . If you want to explore the entire object database, set the maximum altitude limit to 90º and the minimum limit to – 90º.
27 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. Enter this azi muth reading for either th e maximum or minimum azimuth slew limit to ens ure that the telescope will not slew b eyond this point.
28 Light Control – This feature allows you to turn off both the red key pad light and LCD display for daytim e use to conse rve p ower and to help pre serve your night visio n. Factory Se ttings – Returns the Advanced GT hand control to its o riginal factory settings.

31 Figure 4-3 The emblem on the end of the focus knob show s the correct rot ational dire ction for focusing your telescope . Focu si ng The Sc hmidt-Cas segrain focus ing mechanism controls the prim ary mirror w hich is mounte d on a ring that slide s back and forth on t h e prim ary baff le tube.
32 Let’s sa y, for exa mple, you are using t he 40 mm Plossl e yepiece. To deter mine the magni fication you simpl y divide t he focal length of y our teles cope (the C8-S f or exam ple has a focal le ngth of 2032m m) by the foc al length of the ey epi ece, 40mm.
33 Up to this poi nt, this m anual covered the a ssembly and ba sic oper at ion of y our telescope . However , to unders tand y our telesc ope more thoroughly , y ou need to know a little about th e night sky. This section de als w ith observational astronom y in g eneral and i n clude s informa tion on the night sk y and polar a lignm ent.
34 Motion of the Stars The daily motion of the Sun a cross the sky is fam iliar to even the m o st casua l observer. This daily trek is not the Sun mov ing as early as tronomers thoug ht, but the result of the Earth's rotation.
35 Latitude Scales The easiest way to polar align a telescope is with a latitude scale. Unlike other methods that require you to find the celestial pole by ide ntifying certain s tars near it, this meth od works off of a known constant to determine how high the polar axis should be poin ted.
36 4. Center Polaris in the field of the telescope u sing the fine adjustment controls on the mount. Remember, while Polar aligning , do NOT move the telescope in R.A. or DEC. You do not want to move the telescope its elf, but the polar axis. The telescope is us ed simply to see where the polar axis is pointing.
37 Declination Dr ift Method of P olar Alignme nt This method of polar alig nment allows you to get the most accurate alignment on the celestial pole and is required if you want t o do lon g exposure deep-s ky astrophotography through th e telesc ope.
38 With y our telescope set up, y ou are re ad y to us e it for observ ing. This section c overs visua l observing hints for both solar sy stem and deep sky objects as w ell as general observ ing conditio ns which w ill affect your a b ility to observe.
39 Never proj ect an image o f the Sun through t he telesco pe. Because of th e folded op tical d esign, tremend ous heat build- up will result inside the optic al tu be. This can dam age the telescope and/or a n y accessories a ttached to the telescope .
40 rays from the sa me object arriv e slightly disp laced creatin g an imperfect o r smeared i mage. These at mospheric distu rbances vary from time-to- time and p lace-to-pl ace. The size of the air p arcels compared to your aperture determ ines the "seeing" quality.
41 After looking at the night sky for a while you may want to try photographing it. Several forms of celestial photography are possible with your telescope, including short exposure prim e focus, eyepiece projection, long ex posure deep sky, terres trial and even CCD imaging.
42 • T-Ma x 400 • Any 100 to 400 I SO color sli de film • Fuji Supe r HG 400 • Ektar 25 or 100 2. Ce nter the Moon i n the fie ld of y our teles cope. 3. Focus the te lescope by turning th e focus knob u ntil the imag e is sharp. 4. Set the shutter speed to the appropriate setting (see ta ble below).
43 act as a sh utter. The card prevents li ght from enterin g the telesco pe while th e shutt er is released. On ce the shu tter has been re leased and the vi bration ha s diminished (a few se conds), move the bla ck card out of the w a y to expos e the film.
44 There are seve ral techniques f or this type of photog raphy, and the one chosen will dete r mine the standard accessories needed. T he best me thod for lon g exposure deep sky astrophotogr aphy is with a n off-axis guide r. This de vice allows you to phot ograph an d guide through the telescope s imulta neously .
45 There is no exposure de termination ta ble to help y ou get star ted. The best way to dete r mine exposure leng th is look at previous ly publishe d photos to see w hat film/ex posure com binations were used. Or take unguided sa mple photos of various parts of the sky while the drive is run n ing.
