I'm using SkySafari Pro 5 on my MacBook Pro and can't get night vision mode to work properly. When I activate night vision, the entire screen goes to red but then everything but the main window returns to normal; the main window showing the sky remains red. I was thus unable to use the app while on our eclipse trip this past week because the glare was too much. I searched for settings that would perhaps turn the entire screen to red but found nothing. Please help.
