Another tip for screenshots.
In addition to using F3 and F4 for external views you can use F5.
The advantage to F5 is avoiding the wide angle lens effect where anything in the center appears larger than objects further away. This is caused by the viewpoint location's effect on perspective. F5 puts the viewpoint further away.
The problem with F5 is zooming in enough. The trick to increase zoom is to start in the cockpit view and zoom in until the gunsight fills the screen. Then use F5 and you will see an increase in the zoom range. This creates the effect of telephoto compression.
