1.   Stand the tripod legs upright and spread the legs out as far  

as they will go. Keep the tripod legs at their shortest (fully 
retracted) length, for now; you can extend them to a more  
desirable length later, after the scope is fully assembled. 

2.  Place the base of the equatorial mount into the tripod head. 

Orient the equatorial mount so that the post on the tripod  
head lines up with the azimuth adjustment knobs on the  
equatorial mount (Figure 2). You may need to loosen the  
azimuth  adjustment  knobs  on  the  equatorial  mount  in 
order to fit the mount onto the tripod head.

3.   Thread the central support shaft into the equatorial mount 

until tight. This will secure the equatorial mount to the tri-
pod head.

4.   Remove the knob and washer from the bottom of the cen- 

ter support shaft. Slide the tripod support tray up the bot- 
tom of the central support shaft until the three tray arms are 
touching the legs of the tripod. The flat side of the accesso- 
ry tray should be facing up. Make sure the “V” of each tray 
arm is against a tripod leg. Place the washer back on the  
center support shaft against the tray, and thread the secur- 
ing knob all the way up the center support shaft until it is  
tight against the tray. The tripod support tray provides addi- 
tional stability for the tripod, and holds five 1.25" eyepiec-
es and two 2" eyepieces.

5.   Thread the latitude adjustment L-bolts into the equatorial  

mount  where  shown  in  Figure  1. Thread  one  L-bolt  in 
about halfway, then thread the other L-bolt in until tight. 

6.   Thread the counterweight shaft into the equatorial mount at 

the base of the declination axis until tight. Make sure the  cast-
ing at the top of the shaft is threaded counter-clockwise as far  
as it will go before attaching the shaft. Once the shaft is  
installed, turn the casting clockwise until the top of the 
casting is flush with the mount.

7.  Remove the knurled “toe saver” retaining screw on the bot-

tom of the counterweight shaft and slide the counterweight  
onto the shaft. Make sure the counterweight lock knob is  
adequately loosened to allow the counterweight shaft to  

pass through the hole. Position the counterweight about  
halfway up the shaft and tighten the lock knob. Replace the 
toe saver at the end of the bar. The toe saver prevents the  
counterweight from falling on your foot if the lock knob hap- 
pens to come loose.

8.  Attach the slow-motion control knobs to the right ascension 

and declination worm gear shafts of the equatorial mount  
by sliding them onto the shafts. Line up the flat surface 
on the shaft with the corresponding feature on the interior 
of the knob to connect them properly. The knobs can be  
attached to either end of the shafts; use whichever end is  
most convenient.

9. Attach the tube mounting rings to the tube ring mounting  

plate using the attachment screws that are on the tube  
rings. The screws should go through the holes on the outer 
ends of the mounting plate and rethread into the tube rings. 
Note that the side of the mounting plate with the central  
“groove” will be facing up. Use the small crescent wrench  
to secure the tube rings to the mounting plate.

10. Loosen the black mounting plate securing knob as well as 

the metal safety screw on the top of the equatorial mount.  
Place the tube ring mounting plate, with the tube rings  
attached, in the dovetail slot on top of the equatorial mount. 
Position the mounting plate so that it is centered on the  
dovetail slot. Re-tighten the mounting plate securing knob  
until the mounting plate is secure. Then, tighten the safety  
screw. The  safety  screw  will  ensure  that  the  mounting 
plate  (and telescope tube) will not fall off the EQ mount if the  
mounting plate securing knob should come loose.

11. Lay the telescope optical tube in the tube rings at about 

the midpoint of the tube’s length. Rotate the optical tube 
so that the focus knobs are pointed down. Close the rings 
over the tube and tighten the knurled ring clamps finger 
tight to secure the telescope in position.

installing the Finder Scope

To  place  the  finder  scope  (Figure  3a)  in  the  finder  scope 
bracket, unthread the two black nylon screws until the screw 
ends are flush with the inside diameter of the bracket. Place 
the O-ring that comes on the base of the bracket over the body 
of the finder scope until it seats into the slot on the middle of 
the finder scope. Slide the eyepiece end (narrow end) of the 
finder scope into the end of the bracket’s cylinder opposite the 
adjustment screws while pulling the chrome, spring-loaded 
tensioner on the bracket with your fingers (Figure 3b). Push 
the finder scope through the bracket until the O-ring seats just 
inside the front opening of the bracket cylinder. Release the 
tensioner and tighten the two black nylon screws a couple of 
turns each to secure the finder scope in place. Insert the base 
of the finder scope bracket into the dovetail holder on top of 
the focuser. Lock the bracket into position by tightening the 
knurled thumb screw on the dovetail holder.

Figure 2. 

Orient the equatorial mount so that the post on the 

tripod head lines up with the azimuth adjustment knobs on the 
equatorial mount.
