3 1. Unpacking The entire telescope system will arrive in one bo x. Be careful unpacking the bo x. W e recommend k eeping the original ship- ping containers.
4 3. Assembly Assembling the telescope f or the first time should take about 30 minutes. No tools are needed other than the ones provid- ed. All bolts should be tightened securely to eliminate flexing and wobb ling, b ut be careful not to o v er-tighten or the threads ma y strip.
5 sure to loosen the R.A. and Dec. lock knobs bef ore doing this. Retighten the R.A. and Dec. loc k knobs once the equatorial mount is proper ly oriented.
6 The telescope is now balanced on the R.A. axis. It is not nec- essar y to balance the telescope on the Dec. axis, since the optical tube’ s mounting block is positioned so that the tele- scope will automatically be balanced on that axis.
7 Focusing the Finder Scope If , when looking through the finder scope, the images appear somewhat out of f ocus, you will need to ref ocus the finder scope f or your e y es. Loosen the lock ring located behind the objective lens cell on the body of the finder scope (see Figure 5).
8 The equatorial mount is now polar aligned f or casual obser v- ing. More precise polar alignment is recommended f or astrophotograph y . F rom this point on in your obser ving session, you should not make an y further adjustments in the azimuth or the latitude of the mount, nor should you mo v e the tripod.
9 Figure 7. For Northern Hemisphere obser vers, use the lower set of number s on the R.A. setting circ le. The R.A. coordinate indicator arr ow is between the “R” and the “A” on the plastic gear cover . The telescope (not shown) is pointing north of the celestial equator , so the appro ximate coordinates of the mount in the image are R.
10 Figure 8a, 8b, 8c, 8d. This illustration shows the telescope pointed in the four car dinal directions: (a) north, (b) south, (c) east, (d) west. Note that the tripod and mount have not been mo ved; only the telescope tube has been moved on the R.A.
11 an obser v er to own five or more e yepieces to access a wide range of magnifications. This allo ws the observer to choose the best ey epiece to use depending on the object being vie w ed.
12 SA TURN The ringed planet is a breathtaking sight when it is well positioned. The tilt angle of the r ings varies ov er a per iod of many y ears; sometimes they are seen edge-on, while at other times they are broadside and look lik e giant “ears” on each side of Saturn’s disk.
13 Continue using stars as guideposts in this wa y until you are at the appro ximate position of the object you are trying to find (Figure 9). Look in the telescope’ s ey epiece, and the object should be somewhere within the field of vie w . If it’s not, s weep the telescope carefully around the immediate vicinity until the object is f ound.

Collimating is the process of aligning a telescope’ s optics. Y our StarMax or Apex’ s pr imary mirror was aligned at the f actor y and should not need adjustment unless the telescope is handled roughly .
Once you are ready to collimate , look into rear opening of the tube. If your telescope is out of collimation, it will resemble Figure 2a, a properly collimated scope will resemble Figure 2b . The direction of the misalignment in your telescope ma y diff er from Figure 2a, but the diag ram will giv e you the gen- eral idea of how things will look.
If the alignment screw is a lar ge screw First, using the 3mm Allen wrench, turn t he large screw cloc k- wise a small amount, no more than a 1/4 turn. (Figure 4a) Now , with the 2mm Allen wrench tur n the two adjacent small screws (Figure 4b) countercloc kwise no more than 1/4 turn.
