Depends on the brightness setting. With brightness all the way up, you cant see the bird through the image, but instead have to look above/below or from the sides. Sunlight is a NON issue with the Moverio, when you use the darkest sun shields. I was flying and looking directly into a very bright pre-sunset with no issues last weekend.t looks on YouTube videos to be kind of a hologram HUD that is very transparent? How does the sun light affect them?
