1. unpacking
The entire mount will arrive in two boxes, one containing the
tripod, the other containing the equatorial mount. Be care-
ful unpacking the boxes. We recommend keeping the boxes
and original packaging. In the event that the mount needs to
be shipped to another location, or returned to Orion for war-
ranty repair, having the proper packaging will ensure that your
mount will survive the journey intact.
Make sure all the parts in the Parts List are present. Be
sure to check the box carefully, as some parts are small.
If anything appears to be missing or broken, immediate-
ly call Orion Customer Support (800-676-1343) or email
support@telescope.com for assistance.

3. assembly
1. Stand the tripod legs upright and spread the legs out as
far as they will go. Make certain that the leg lock levers
are tightened. 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. Place the base of the equatorial mount onto 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.

lines up with the azimuth adjustment knobs on the equatorial mount.
3. Remove the knob and washer from the bottom of the
center support shaft. Slide the tripod support tray up the
bottom of the central support shaft until the three tray
arms are touching the legs of the tripod. The flat side of
the support tray should be facing up. Make sure the "V" of
each tray arm is against a tripod leg. Place the washer on
the center support shaft against the tray, and follow it by
threading the knob all the way up the center support shaft
until it is tight against the tray. The tripod support tray pro-
vides additional stability for the tripod, and holds up to five
1.25" eyepieces and two 2" eyepieces.
4. Loosen the counterweight shaft lock lever and fully extend
the counterweight shaft. Retighten the lock lever.
5. Remove the knurled "toe saver" retaining screw on the bot-
tom of the counterweight shaft and slide the counterweight
