Congratulations on your purchase of an Orion telescope. Your new GoScope 70 is the most portable

telescope system ever developed by Orion. Since it fits completely in its included backpack case, you
can take the GoScope on camping trips, day hikes, the beach, sporting events, vacations, and anywhere
else you want to bring it. Great for daytime spotting or nighttime stargazing, the GoScope offers the entire
family new worlds of fun.

These instructions will help you set up, properly use and care for your telescope. Please read them over
thoroughly before getting started.

WARNING: Never look directly at the Sun through
your telescope—even for an instant—without a
professionally made solar filter that completely
covers the front of the instrument, or permanent
eye damage could result. Young children should
use this telescope only with adult supervision.

Assembly

Carefully remove all of the items from the shipping box. Make
sure all the parts listed in the parts list are present. Save all
boxes and packaging material. In the unlikely event you need to
return the telescope, you should use the original packaging.

Assembling the telescope is very easy and quick to do. No
tools are required. During assembly (and anytime for that mat­ter), do not touch the any of the lenses of the telescope, eye­pieces, or finder scope with your fingers. The optical surfaces
can become dirty or damaged if touched. Never remove any
lens assembly from its housing for any reason, or the product
warranty and return policy will be voided.

Refer to Figure 1 during assembly.

1. Spread the legs of the tripod, and extend them to the
desired length. Extend the legs by disengaging the leg
clamps and pulling the leg sections out. Re-engage the
clamps when done.

2. Remove the quick-release shoe from the top of the tri­pod. To do this, you must first push the quick-release lever
(Figure 2a).

3. Attach the quick-release shoe to the mounting block on the
GoScope optical tube (Figure 2b). Thread the stud on the
shoe into the threaded hole in the mounting block. Use the
knurled edge of the screw on the underside of the shoe to

pushing the quick-release lever while simultaneously lifting the quick
release shoe with the other hand.

mounting block as shown.

secure it to the tube. You can use a small flathead screw
driver or the edge of a coin to firmly tighten the connection.

4. Attach the 45° erect-image diagonal to the optical tube.
First remove the caps from the diagonal and unthread
the cover on the rear of the GoScope. The knurled ring
on the diagonal connects to the threads on the rear of the
GoScope (Figure 3). Tighten this ring firmly. If you wish
to change the orientation of the diagonal for a more com­fortable viewing angle, you must first loosen the knurled
ring on the diagonal. Rotate the diagonal to the desired
viewing angle, and retighten the knurled ring to lock the
diagonal into place.

threads on the rear of the GoScope. To change the viewing angle,
loosen the knurled ring, rotate the diagonal, then retighten the ring.

Figure 5. The GoScope tripod moves about two axes of motion:

altitude (up-and-down) and azimuth (left-to-right).

5. Insert the 20mm eyepiece into the diagonal (remove the
caps from the eyepiece). Secure the eyepiece with the
thumbscrew on the diagonal.

6. Connect the EZ Finder II reflex sight to its bracket on the
telescope tube. Loosen the two knurled silver thumbscrews
on the reflex sight, and slide its base onto the rail on top
of the bracket. The reflex sight should be oriented on the
GoScope as shown in Figure 4. Retighten the knurled sil­ver thumbscrews so the EZ Finder II is firmly connected to
its bracket.

7. Re-connect the tripod’s quick-release shoe, now with the
GoScope attached, to the tripod. Push the quick-release
lever to allow the shoe to seat onto the tripod head.

Your telescope is now fully assembled and should resemble
Figure 1.

Using the Tripod

The tripod allows motion of the telescope either left-to-right
(azimuth) or up-and-down (altitude) (Figure 5). To move the
telescope in azimuth, first loosen the azimuth lock knob
(Figure 1). You do not need to completely loosen this knob,

as having some tension makes pointing the telescope easier.
To move the telescope in altitude, first rotate the tripod handle
(Figure 1) counterclockwise. Again, do not completely loosen
the handle, or the telescope will move too freely and become
difficult to point.

Once the telescope is pointing where you wish, you can re­tighten the azimuth lock knob and rotate the handle clockwise
to lock the tripod position into place.

For additional tripod height, you can extend the elevator shaft
of the tripod. First loosen the elevator shaft lock knob, and use
the hand crank to raise or lower the telescope to the desired
height (Figure 1). Tighten the lock knob firmly when done.

The tripod also has a third axis of motion, as the telescope
can be rotated 90° to the left about the axis parallel to the
telescope’s body. Because this is a photo tripod, this fea­ture allows you to rotate a camera from portrait to landscape
mode. This feature will rarely, if ever, be used with a tele­scope. However, if you wish to rotate the telescope in this
way, first loosen the third axis lock knob (Figure 6), make your
adjustment and retighten the knob.
