Collimating the Optics
Collimation is the process of aligning the telescope's optics. Since the primary mirror does not come installed in the optical tube, we recommend
collimating the optics before your first night out. It is easiest to collimate a telescope during the day with the telescope pointed toward a blank
wall. This will provide a high-contrast view, making it easier to determine which adjustments to make. Use the supplied hex key(s) to make
adjustments.

2. Look through the small hole in the center of the collimation cap. If your
view matches the first image, your optics are collimated properly and

to adjust the mirrors' alignment. Continue to step 3.
