1. Assembly

1. Stand the tripod (A) upright and spread the legs apart a 

little. Keep the tripod legs at their shortest (fully retracted) 

length for now; you can extend them to a more desirable 

length later, after the mount is fully assembled.

2. To attach the accessory tray (C), place a hooked tab on one 

of the three corners of the tray over the screw in the leg col-

lar, as shown in Figure 2A. Connect the tray to the other two 

legs in the same manner (2B), then tighten all three of the 

tray lock knobs (2C) to secure the tray in place. 

3. Now you’ll install the altazimuth arm (B) onto the tripod. 

Remove the azimuth tension knob and washer from the cen-

ter shaft on the bottom of the arm. Then place the base of the 

arm on the tripod’s mounting platform, inserting the center 

shaft into the hole in the tripod’s mounting platform. (NOTE: 

The large plastic disk, which is identified in Figure 1, 

goes between the mounting arm and the tripod’s mount-

ing platform.) Then replace the washer and azimuth tension 

knob to secure the arm in place (Figure 3)

4. Attach the two micro-motion cables (D). The shorter of the two 

is usually preferred for the altitude axis and the longer one 

for the azimuth axis. Loosen the thumbscrew at the end of 

the cable, then line up the cable end so that the thumbscrew 

is over the flat side of the axle on each axis (Figure 4). Press 

the cable end over the axle, then tighten the thumbscrew to 

secure the cable in place. The thumbscrew should protrude 

down into the dimple in the axle, to insure that the cable will 

not slip off the axle. Once attached the micro-motion cables 

should appear as in Figure 5

Attaching the Telescope Optical Tube 

to the Mount

The E-Series Altazimuth Mount features a dovetail mounting 

saddle that accommodates Vixen-style mounting bars

 

(Figure 

6A). Slide the dovetail bar attached to the side of the optical 

tube into the saddle, then secure it in place by tightening the 

saddle lock knob (Figure 6B). (You may have to loosen the 

saddle lock knob a little before attempting to slide in the dovetail 

bar, to allow clearance for the bar.)

Installing the Accessories

With the tube now securely attached to the mounting arm, 

install the red dot finder scope (H) on the optical tube. Do this 

by orienting the finder scope as shown in Figure 7 and slide the 

bracket foot back into the finder scope base as far as it will go. 
Now insert the correct-image diagonal (I) into the focuser draw-

tube and tighten the thumbscrew on the drawtube collar. Then 

insert the 25mm eyepiece (F) into the diagonal and secure it by 

lightly tightening the thumbscrew on the diagonal (Figure 8)
The telescope is now completely assembled and should appear 

as in Figure 9! Before it can be effectively used, however, there 

are a couple of things to do to prepare the telescope for opera-

tion.
