Adjusting reticle in the 110?

[Flashman]

There is a command for it. In the GENERAL tab for controls look for increase and decrease gunsight illumination.

In the german planes the illumination level is gradual (in 5% steps) so to fully light up the sight keep the button down.

Whereas the british planes are on or off. (though I did recently read a BoB pilots account of fighting in a Hurri and he talks about adjusting his sight illumination)
