Hello.
From an old post
“
Orion Internal Contrast Control
From the Orion Reflector April 3, 2006
The internal contrast needs to be set. This control is accessible through a
small hole on the bottom right of the front panel (looking from the front) with
the bottom cover removed. Set the internal contrast to 50% and adjust this
control for proper contrast.
