1.Unpacking

The entire telescope will arrive in three boxes, one contain‑ ing the tripod, one containing the equatorial mount, and the third box containing the optical tube. Be careful unpacking the boxes. We recommend keeping the boxes and original pack‑ aging. In the event that the telescope needs to be shipped to another location, or returned to Orion for warranty repair, hav‑ ing the proper packaging will 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.
