1. Unpacking

The SkyView Pro 120 EQ will arrive in one box. Be careful unpacking the box. We recommend keeping the box and all original packaging. In the event that the telescope needs to be shipped to another location, or returned to Orion for warranty repair, having the proper box and packaging will help ensure that your telescope will survive the journey intact.

Make sure all the parts in the Parts List are present. Be sure to check each 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.

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.

3.Assembly

Assembling the telescope for the first time should take about 30 minutes. No tools are needed other than the ones provided. All screws should be tightened securely, but be careful not to over-tighten or the threads may strip. Refer to Figure 1 during the assembly process.

During assembly (and anytime, for that matter), do not touch the surfaces of the lenses of the telescope, finder scope or eyepieces with your fingers. The optical surfaces have delicate coatings on them that can easily be damaged if touched inap- propriately. Never remove any lens assembly from its housing for any reason, or the product warranty and return policy will be voided.
