2. assembly
Carefully open all of the boxes in the shipping container.
Make sure all the parts listed in the parts list are present.
Save the boxes and packaging material. In the unlikely
event that you need to return the telescope, you must use
the original packaging.
Assembling the telescope should take only about 30 minutes.
All screws should be tightened securely to eliminate flexing
and wobbling, but be careful not to over-tighten or threads
may strip. No tools, other than the ones provided, are need-
ed. Refer to Figure 1 during assembly.
During assembly (and anytime, for that matter), do not touch
any of the lenses of the telescope, finder scope, or eye-
pieces, or the mirror of the diagonal, with your fingers. The
optical surfaces have delicate coatings on them that can be
damaged if touched inappropriately. Never remove any lens
assembly from its housing for any reason, or the product
warranty and return policy are void.
1. Lay the altazimuth mount on its side. Attach the tri-
pod legs one at a time to the mount using the screws
installed in the tops of the tripod legs. Remove the
screw from the leg, line up the holes in the top of the
leg with the holes in the base of the mount, and reinstall
the screw so it passes through the leg and the mount.
A washer goes between the screw head and the tripod
leg, and between the wingnut and tripod leg. Tighten the
wingnuts only finger-tight, for now. Note that the acces-
sory tray bracket attachment point on each leg should
face inward.
2. Tighten the leg lock knobs at the base of the tripod legs.
For now, keep the legs at their shortest (fully retracted)
length; you can extend them to a more desirable length
later, after the scope is completely assembled.
3. With the tripod legs now attached to the altazimuth
mount, stand the tripod upright (be careful!) and spread
the legs apart enough to connect each end of the acces-
sory tray bracket to the attachment point on each leg.
Use the screw that comes installed in each attachment
point to do this. First remove the screw, then line up one
of the ends of the bracket with the attachment point and
reinstall the screw. Make sure the accessory tray bracket
is oriented so the ribs in its plastic molding face down-
ward.
4. Now, with the accessory tray bracket attached, spread the
tripod legs apart as far as they will go, until the bracket is
taut. Attach the accessory tray to the accessory tray
bracket with the three wingnut-head screws already
installed in the tray. This is done by pushing the screws
up through the holes in the accessory tray bracket, and
then threading them into the holes in the accessory tray.

ongratulations on your purchase of a quality Orion telescope.
Your Explorer altazimuth refractor is an excellent
instrument for both terrestrial observation and astronomical viewing. Whether it’s a distant ship at sea, a bird across a field, or
a planet in the sky, the Explorer will bring you closer to what you wish to observe. If you have never used a telescope before,
we would like to welcome you to a new world of adventure. With a little practice and patience, you’ll find your telescope to be a
never-ending source of wonder, exploration, and relaxation.
Warning:
Never look directly at the Sun
through your telescope or its finder scope—
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.
