The only thing you forgot to do and i can't belief others didn't see this

Only the last picture shows the slider moved to the left completely.
I should be about a quarter from the left.
My guide camera gamma is normally on 95%.
The slider doesn't change the camera gamma at all.
slide the bottom slider to the left till you can see the picture appear, this is in the main PhD window.
This slider is there so humans can see stars and pick one for guiding
