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.

1. Unpacking

The entire telescope system will arrive in one box.
Be careful unpacking the box. We recommend
keeping the original shipping container. In the
event that the telescope needs to be shipped to
another location, or returned to Orion for warranty
repair, having the proper shipping container will
help ensure that your telescope will survive the
journey intact.

Make sure all the parts in the Parts List are pres-
ent. Be sure to check the box carefully, as some
parts are small. If anything appears to be missing
or broken, immediately call Orion Customer
Support (800-676-1343) for assistance.
