The installation of an eyepiece pointer is pretty straightforward. All you need is an eyepiece and an eyepiece pointer (available in 23mm or 30mm). No tools are necessary but we do recommend wearing thin gloves to avoid getting smudges or dirt into the eyepiece lens.
To make installation easier, place the eyepiece and pointer on a flat, clean surface.
Step 1. Turn eyepiece upside down so that inside of eyepiece tube is exposed
Step 2. Place pointer into the open eyepiece tube
Step 3. Squeeze aluminum clip and place in open eyepiece tube
Your eyepiece with pointer should be ready for use.
