North Hemisphere:

1. Mount the illuminator provided to the polar scope. With the light it gives, you can see the reticle better in the dark.

Please mount it at the end of the polar scope, and shine it with a light source like a headlamp or phone light, it will glow in dark. (Please test it in a dark room or dark environment).

2. For iOS users, please download and open the app "Polar Scope Align Pro"; For  Android users, please download and open the app “Polar Finder Pro”.  Select the iOptron reticle.
