Or you can take it without hiding after creating a hot key.
IIRC:
/bind F11 screenshot_jpg (where "F11" is the key it would be bound to, and "screenshot_jpg" means it would be without HUD).
You need to do it separately for ground and space. Then you just press F11 (or whatever is the key of your choice), and you get a clean picture in your screenshot folder.
